Warning Review limit reachedYou’ve reached a temporary PR review limit under our Fair Usage Limits Policy. Next review available in: 12 minutes Limit details: You’ve used all 1 included review currently available under your plan. You completed 89 included PR reviews in the past 7 days; at that activity level, included reviews refill at 1 review per hour. Enable usage-based reviews in Billing to review now. Otherwise, wait until the next included review is available. How can I continue?After more reviews become available, a review can be triggered using the To avoid repeated limits, reduce automatic review volume by pausing incremental auto-reviews earlier, using label-based review opt-in, excluding WIP or generated PR titles, or requesting reviews manually when the PR is ready. If your team needs uninterrupted high-volume reviews, an organization admin can enable usage-based reviews. How do review limits work?CodeRabbit enforces per-developer PR review limits for each organization. Most developers receive the normal plan review availability. For paid Pro and Pro+ PR reviews, CodeRabbit uses adaptive limits for sustained high-volume activity. When a developer's recent PR review activity reaches the 95th percentile or higher among CodeRabbit users, additional reviews become available more gradually as earlier reviews age out of the rolling window.

Merge Risk: 🟠 High · up to 90c47
This change introduces vTPM, secure-boot, host-file, key-management, and snapshot lifecycle behavior, but the current head still contains concrete failure paths that can time out requests, mis-handle or leak sensitive data, leave inconsistent storage metadata, or lose TPM encryption state during rollback. It is not safe to merge until the high-impact correctness, security, and rollback issues are fixed or explicitly accepted.

In previous versions, the global config "enable.uefi.secure.boot" had no practical effect, as its default value was "true". In the current version, since it affects numerous configurations, its default value has been changed to "false" to maintain consistency with VM startup settings from previous versions and minimize the risk of VM configuration changes.

VmTpmExtensions so the value returned by getResourceConfigValue is compared with
Boolean.TRUE.equals(...), preserving NvRam registration whenever the
configuration value is logically true.
Apply the same fix in
`@plugin/kvm/src/main/java/org/zstack/kvm/efi/KvmSecureBootExtensions.java` around
lines 161 - 167: The same boxed-Boolean comparison affects the secure-boot
migration path.
In `@compute/src/main/java/org/zstack/compute/vm/devices/VmTpmManager.java`:
- Around line 53-62: 更新 needRegisterNvRam：无 TPM 时先通过
VmTpmManager.isUefiBootMode(...) 判断 UEFI 启动模式，仅在 UEFI 模式下检查
ENABLE_UEFI_SECURE_BOOT 配置，并使用 Boolean.TRUE.equals(...) 处理资源级或全局配置为 null
的情况；保持已有 TPM 存在时直接返回 true 的行为。
In `@conf/db/upgrade/V5.5.38__schema.sql`:
- Around line 3-10: Enforce the one-TPM-per-VM constraint at both sites: in
conf/db/upgrade/V5.5.38__schema.sql lines 3-10, add the unique key
ukTpmVOVmInstanceUuid on vmInstanceUuid; in

27-39, update persistTpmVO to check for an existing TpmVO for the vmUuid and
return a clear error instead of inserting a duplicate.
In
`@header/src/main/java/org/zstack/header/storage/snapshot/CreateVolumesSnapshotMsg.java`:
- Around line 19-20: 补全创建卷快照消息链路：在处理 CreateVolumesSnapshotMsg 的逻辑中，将
backupHostFileIfNeeded 传递到 CreateVolumesSnapshotOverlayInnerMsg；完成内部调用后，再将
CreateVolumesSnapshotOverlayInnerReply.hostBackupFileUuidList 复制到

In `@plugin/kvm/src/main/java/org/zstack/kvm/BootKvmStartVmExtension.java`:
- Around line 43-46: 更新 afterReceiveVmDeviceInfoResponse：获取 UUID 时兼容两条调用路径，spec
非空时使用 spec.getVmInventory().getUuid()，否则使用 vm.getUuid()，再传入
saveVmEdkStatesFromCommand，避免任一合法路径因另一参数为 null 触发 NullPointerException。
In `@plugin/kvm/src/main/java/org/zstack/kvm/efi/KvmSecureBootManager.java`:
- Around line 446-449: Update the query in the backup-file collection flow to
use VmHostBackupFileVO_.type instead of VmHostFileVO_.type when filtering
missingTypes, while preserving the existing resourceUuid condition and result
handling.
- Around line 455-468: Update the flow around the run method to avoid executing
the Q.New query with an empty uuidList when context.files is empty; use an empty
filesAfterSyncing result in that case, then still call backupVmHostFile with
context.backupFiles and continue via trigger.next().
- Around line 280-296: 在处理文件内容的回调中，围绕 Base64 解码和格式转换增加对 to.getContentBase64() 与
to.getFileFormat() 的非空校验；任一字段缺失时记录该文件路径的错误并跳过当前文件，继续处理其余文件。确保校验发生在创建或持久化

引用的快照组；保持现有 handle 创建并持久化 VolumeSnapshotGroupVO 的逻辑不变。
- Around line 408-426: Update the snapshot-group restore flow around the
restore-vm-host-file step to skip restoration when backupFiles is empty and the
target VM has existing NvRam or TpmState files but no VmHostBackupFileVO
records. Avoid generating Delete operations or removing the current host files
and database records for such snapshots, while preserving normal restoration
when host-file backups exist.
In
`@storage/src/main/java/org/zstack/storage/snapshot/VolumeSnapshotApiInterceptor.java`:

QCOW2 system tag. Also update the success callback to persist the actual
cmd.format instead of hardcoding VOLUME_FORMAT_RAW.
In `@plugin/kvm/src/main/java/org/zstack/kvm/KVMHost.java`:
- Around line 5532-5537: Update

the existing error-handling path to expose the failure during secret definition.
In `@plugin/kvm/src/main/java/org/zstack/kvm/tpm/KvmTpmExtensions.java`:
- Line 66: Update the host-file persistence flow in KvmTpmExtensions around
hostFileLock to handle cross-management-node unique-key conflicts: catch the
unique-constraint failure from persist, reload the existing ukVmHostFileVO by
its vmInstanceUuid, hostUuid, and type identity, then continue with the intended
update instead of failing. Follow the save-or-update conflict recovery pattern
used by HostKeyIdentityHelper.saveOrUpdateHostKeyIdentity while preserving the
existing single-node lock behavior.
In `@plugin/kvm/src/main/java/org/zstack/kvm/tpm/KvmTpmManager.java`:
- Around line 209-223: Update the check-vm-status flows in both locations to

NullPointerException.
- Around line 481-512: 在 handle(APIGetTpmCapabilityMsg) 中查询 TPM 和关联 VM 后立即判空：TPM

Use value comparison for secure-boot/NVRAM enablement. The code compares boxed Boolean values with == in two paths. Use Boolean.TRUE.equals(...) so non-cached instances and null values produce the intended result consistently.

“一台虚拟机最多一个 TPM”这一约束没有任何强制点。 读取侧（TpmMessageAutoCompleter、VmTpmExtensions.afterBuildVmSpec）用 findValue() 按 vmInstanceUuid 取单值，但数据库与写入侧都不阻止重复记录。
conf/db/upgrade/V5.5.38__schema.sql#L3-L10：在TpmVO上增加UNIQUE KEY ukTpmVOVmInstanceUuid (vmInstanceUuid)。compute/src/main/java/org/zstack/compute/vm/devices/VmTpmManager.java#L27-L39：在persistTpmVO中先校验该vmUuid是否已存在TpmVO，存在时返回明确错误而非再次插入。

同步路径传入 spec == null，启动路径传入 vm == null。使用 spec != null ? spec.getVmInventory().getUuid() : vm.getUuid() 获取 UUID，避免两条路径触发 NullPointerException。

🌐 Web query:
Search GitHub for the ZStack KVM agent implementation of the endpoint "/localstorage/volume/createempty" and determine whether its handler uses the "volumeFormat" request field, including the relevant repository and source link.
💡 Result:
The ZStack KVM agent endpoint /localstorage/volume/createempty is associated with the CreateEmptyVolumeCmd command [1]. Based on the available source code examples, the CreateEmptyVolumeCmd command does not include a volumeFormat field; its defined fields are installPath, size, name, and volumeUuid [1]. In ZStack, the volume format is generally managed as a property of the volume itself (e.g., set to VOLUME_FORMAT_QCOW2 by the management layer upon successful creation) rather than being passed as a request parameter to the KVM agent during the creation of an empty volume [1][2]. The primary ZStack repository on GitHub, zstackio/zstack, contains the relevant plugin implementations for local storage, specifically within the org.zstack.storage.primary.local package [3][4][5].

Search GitHub zstackio/kvmagent and zstackio/zstack for the exact handler of "/localstorage/volume/createempty", the CreateEmptyVolumeCmd schema, and any use of a "volumeFormat" field. Prefer current source over mirrors or old snapshots.
💡 Result:
In the ZStack architecture, the path /localstorage/volume/createempty is a REST API endpoint exposed by the KVM agent (kvmagent) to handle local storage volume creation requests [1][2]. 1. Handler for /localstorage/volume/createempty: This endpoint is handled by the Local Storage plugin within the KVM agent. While the management node sends instructions as API messages (e.g., LocalStorageCreateEmptyVolumeCmd), the kvmagent Python service maps this path to a specific handler method in its local storage plugin (typically located under kvmagent/plugins/local_storage_plugin.py). The handler receives the command, interacts with the local filesystem or LVM to create the volume, and returns a LocalStorageCreateEmptyVolumeReply [2]. 2. CreateEmptyVolumeCmd Schema: The command sent to this endpoint generally includes the following key parameters: - volumeUuid: The unique identifier for the volume to be created [3][4]. - volumePath: The target path on the host where the volume will reside. - size: The requested size of the volume in bytes [3][4]. - installPath: The full path of the volume image. - primaryStorageUuid: The UUID of the local primary storage [3][4]. 3. VolumeFormat usage: The volumeFormat field is a core concept in ZStack used to define the relationship between a volume and a hypervisor, such as qcow2 for KVM [5][6]. - It is tracked as a property of the volume inventory [3][4]. - In the context of KVM-based local storage, the volumeFormat is primarily set to qcow2 [5]. - The system uses the VolumeFormat class in Java to register and validate these types across the management node [6]. - When creating an empty volume, the format is often specified to ensure the underlying storage driver (e.g., qemu-img) initializes the volume with the correct metadata [5].

persist-before-revert-snapshot-in-db 缺少 rollback，失败时会残留空快照组。
该步骤持久化了新的 VolumeSnapshotGroupVO，其 snapshotCount 被设为 snapshots.size()。此时还没有任何 VolumeSnapshotGroupRefVO 关联到它。
Flow.of(...).handle(...).build() 没有注册 rollback。后续的 restore-vm-host-file 或 revert-every-volumes 失败时，该记录会保留在数据库中。用户会看到一个 snapshotCount 不为 0 但没有任何快照引用的快照组。
请为该步骤补充 rollback，删除已持久化的 newGroup。

vmState 可能为 null，第 123 行会抛出 NullPointerException。
第 115-118 行用 Q.findValue() 查询虚拟机状态。如果 group.getVmInstanceUuid() 对应的 VmInstanceVO 已被删除，findValue() 返回 null。
此时第 119 行的 contains(null) 返回 false，代码进入抛异常分支。第 123 行调用 vmState.toString()，抛出 NullPointerException。API 会返回内部错误，而不是可读的校验失败信息。

第一个 flow 缺少回滚，失败时会残留快照与孤儿主机备份文件记录。
handle-create-snapshot-group-message 这一步在存储上创建了卷快照，并在 VmHostBackupFileVO 中生成了主机备份文件记录（UUID 通过 r.getHostBackupFileUuidList() 返回）。该 flow 使用 .then(name, trigger -> ...) 形式，没有 rollback。
后续 persist-snapshot-group 或 persist-vm-host-backup-file 失败时，链只会回滚已注册 rollback 的步骤。已创建的快照与 VmHostBackupFileVO 记录会保留。此时 VmHostBackupFileVO.resourceUuid 还没有被赋值，这些记录成为孤儿：VolumeSnapshotGroupBase 的 ungroup 与 delete 流程都按 resourceUuid 删除记录，无法回收它们。
请为该步骤补充 rollback，删除已创建的快照并清理 hostBackupFileUuidList 中的记录。

Inline comments:
In
`@compute/src/main/java/org/zstack/compute/vm/devices/TpmCascadeExtension.java`:
- Around line 65-87: Update shouldDeferVmAssociatedDeletion to evaluate each
VmDeletionStruct independently instead of returning true for any Delay/Never
entry in the batch. Created-state VMs with effective DBOnly deletion and Direct
VMs must delete TPM during the current cascade; only the corresponding Delay or
Never VM should be deferred. Preserve the existing action-code, parent-issuer,
and context validation while applying the decision at VM granularity.
In `@header/src/main/java/org/zstack/header/vm/VmInstanceSpec.java`:
- Around line 409-410: Update VmInstanceSpec.getDevicesSpec() to lazily
initialize and return a new VmDevicesSpec when the field is null, while
preserving the existing instance for non-null values; leave osSpec unchanged.
In `@plugin/kvm/src/main/java/org/zstack/kvm/efi/KvmSecureBootExtensions.java`:
- Around line 127-131: 在获取 NVRAM 的逻辑中先保存并检查 spec.getDevicesSpec() 的结果是否为
null；仅在非空时调用 getNvRam() 并执行现有的 isNeedRegister() 与 prepareNvRamToStartVmCmd 流程，避免
devicesSpec 缺失时抛出 NullPointerException。
- Around line 607-613: 在重置 TPM 状态的清理流程中，更新删除 VmHostFileVO 的逻辑，使其同时删除对应的
VmHostFileContentVO 记录；参照 afterMigrateVm 中删除前的清理方式，确保按相同 VM UUID 清理内容记录后再删除父记录。
- Around line 197-204: 在执行 VmInstanceVO 查询的流程中，为 findTuple() 返回值增加空值判断，避免 tuple
为 null 时调用 get 导致异常；参考 beforeHaStartVmInstance 中的同类处理，并在记录不存在时保持迁移前置流程的安全返回行为。
- Around line 803-807: 在使用 getLockedVmInstanceUuids() 的第一个元素前，先处理列表为 null
或为空的情况，避免访问索引 0 抛出异常；在无锁定虚拟机时保持快照组创建成功后的扩展流程正常返回，并仅在列表包含元素时继续通过 vmUuid 查询
hostUuid。
In `@plugin/kvm/src/main/java/org/zstack/kvm/efi/KvmSecureBootManager.java`:
- Around line 490-496: Extend the validation condition in the
ReturnValueCompletion.success backup path to reject a null fileFormat alongside
contentBase64 before constructing VmHostFileContentVO. Ensure
VmHostFileContentFormat.valueOf(to.getFileFormat()) is only called after
validation, while preserving the existing error-response behavior.
- Around line 757-763: 在 backupVmHostFile 中执行 Q.New 查询前检查合并后的 uuidList；当
fileList 和 backupFiles 均为空导致 uuidList 为空时，直接返回空列表，避免调用带空集合的 Q.in
查询，并保持非空列表的现有处理流程不变。
Apply the same fix in
`@plugin/kvm/src/main/java/org/zstack/kvm/efi/KvmSecureBootManager.java` around
lines 709 - 722: 同一空 UUID 查询问题出现在同步后的备份文件处理路径。
In `@plugin/kvm/src/main/java/org/zstack/kvm/KVMHost.java`:
- Around line 5461-5471: Update the secret handlers handle(SecretHostGetMsg),
handle(SecretHostDefineMsg), and handle(SecretHostDeleteMsg) to execute requests
through Http.call(...) using its timeout overload instead of invoking
runBeforeAsyncJsonPostExts(headers) followed by restf.asyncJsonPost(...).
Preserve the existing command, headers, callback, and timeout behavior while
ensuring the standard agent parameter upgrade validation and HostVO existence
check run before successful completion.
In
`@storage/src/main/java/org/zstack/storage/snapshot/group/VolumeSnapshotGroupBase.java`:
- Around line 525-547: Implement rollback for the remove-tpm-if-needed flow:
before force-deleting the TPM, back up its encryption key using the existing
BackupTpmEncryptionKeyMsg flow, then on rollback recreate the TPM and restore
the key using the established restore-tpm logic and RestoreTpmEncryptionKeyMsg.
Reuse DeleteTpmKeyBackupMsg for cleanup and ensure rollback failures are
propagated without changing the existing success path.
- Around line 601-620: Update the delete-tpm-key-backup step in
VolumeSnapshotGroupBase so a failed DeleteTpmKeyBackupMsg is treated as
non-fatal cleanup: log a warning containing the error and continue the flow with
trigger.next() instead of calling trigger.fail(r.getError()).
In
`@storage/src/main/java/org/zstack/storage/snapshot/VolumeSnapshotTreeBase.java`:
- Around line 2124-2160: Update cleanVmHostBackupFilesForGroup to expose
completion status and wait for all asynchronous VmHostBackupFileDeletionMsg
operations before returning; do not treat failures as log-only success—preserve
a retryable state or persist a GC task. In VolumeSnapshotTreeBase.java lines
1386-1387, change the caller to delete VolumeSnapshotGroupVO only after cleanup
succeeds or retry work is durably persisted.
In `@storage/src/main/java/org/zstack/storage/volume/VolumeBase.java`:
- Around line 3440-3446: 更新 VolumeSnapshotGroupVO 的回滚删除逻辑，使用
dbf.removeByPrimaryKey(resourceUuid, VolumeSnapshotGroupVO.class) 替代直接 SQL
删除，并保留后续 trigger.rollback()，确保关联的 ResourceVO、SystemTagVO 和
VolumeSnapshotGroupRefVO 一并清理。

orphan query, while preserving the existing isManagedByUs cleanup behavior and

- Around line 507-532: Update sendDeleteCommandToHost and its cleanup callers to
avoid serial blocking across files: use bounded concurrency when issuing
deletion commands, or enforce a per-run file limit, and reduce the per-command
wait from KVM_CMD_TIMEOUT_MS as appropriate. Preserve existing host-existence
checks and deletion success handling while ensuring cleanupActiveVmHostFiles,
cleanupDeletedVmHostFiles, and cleanupExpiredVmHostFiles cannot accumulate
unbounded work.

按 VM 粒度处理 TPM 删除
VmInstanceState.Created VM 的实际删除策略始终为 DBOnly。该路径会硬删除 VM 行，但不会触发 VM_INSTANCE_EXPUNGE_CODE。当 cascade context 中的策略为 Delay 或 Never 时，当前逻辑会跳过 TPM 删除，导致 TpmVO 残留。
当前逻辑还会因批次中一个 VM 使用 Delay 或 Never 而推迟所有 VM 的 TPM 删除。请按 VM 粒度筛选：Created VM 和 Direct VM 在当前 cascade 删除 TPM，只有对应的 Delay 或 Never VM 延迟删除。

In `@compute/src/main/java/org/zstack/compute/vm/devices/TpmCascadeExtension.java`
around lines 65 - 87, Update shouldDeferVmAssociatedDeletion to evaluate each
VmDeletionStruct independently instead of returning true for any Delay/Never
entry in the batch. Created-state VMs with effective DBOnly deletion and Direct
VMs must delete TPM during the current cascade; only the corresponding Delay or
Never VM should be deferred. Preserve the existing action-code, parent-issuer,
and context validation while applying the decision at VM granularity.

为 getDevicesSpec() 增加空值初始化
当上游消息未设置 devicesSpec 时，VmInstanceBase 会将 null 写入 VmInstanceSpec。KvmSecureBootExtensions.java:127 随后直接调用 spec.getDevicesSpec().getNvRam()，会触发 NullPointerException。在 getter 中为 null 值创建 VmDevicesSpec。osSpec 未发现相同的赋值路径。

三个 secret 处理器绕过 Http.call()，丢失升级校验与主机存在性校验。
本类中所有其他 agent 调用都通过 Http.call()。该方法在第 606 行执行 upgradeChecker.checkAgentHttpParamChanges(...)，并在第 647-651 行确认 HostVO 仍然存在后才回调成功。这三个 secret 处理器构造 Http 对象后只调用 runBeforeAsyncJsonPostExts(headers)，然后直接调用 restf.asyncJsonPost(...)，因此：
- 不执行 agent HTTP 参数变更校验，灰度升级期间可能向不兼容的 kvmagent 发送命令；
- 主机在调用期间被删除时仍按成功处理。
同样的问题出现在 handle(SecretHostDefineMsg)（第 5635-5637 行）与 handle(SecretHostDeleteMsg)（第 5681-5683 行）。
建议改用 Http.call(...) 的超时重载，或把这段“构造 header + 直接 post”的逻辑抽成一个私有方法并补上上述两项校验。

remove-tpm-if-needed 缺少 rollback，会造成 TPM 不可逆丢失。
该步骤以 forceDelete=true 删除现有 TPM。代码中的 // TODO: It should has rollback 确认了这一点。
后续的 restore-vm-host-file 或 revert-every-volumes 失败时，流程会回滚。此时 TPM 已被删除，且没有 rollback 恢复它。TPM 中的加密密钥无法重建，虚拟机中依赖 vTPM 的加密卷将无法解锁。
请在删除前先备份该 TPM 的加密密钥，并在 rollback 中重建 TPM 并恢复密钥。本文件的 restore-tpm 步骤已有 BackupTpmEncryptionKeyMsg/RestoreTpmEncryptionKeyMsg 与 DeleteTpmKeyBackupMsg 可复用。
如果需要，我可以生成该 rollback 的实现草案，或创建一个 issue 跟踪该 TODO。

delete-tpm-key-backup 失败会触发整链回滚，导致 TPM 密钥与已还原的卷不一致。
该步骤只删除还原过程中产生的临时 TpmKeyBackupVO。失败时它调用 trigger.fail(r.getError())。
trigger.fail 会回滚整个链。回滚会执行 restore-tpm 的 rollback，把 TPM 加密密钥回退到还原前的版本。但此时 revert-every-volumes 已经完成，卷数据已经是快照时刻的状态。结果是 TPM 密钥与卷数据不匹配，虚拟机中的加密卷可能无法解锁。
临时备份记录删除失败属于清理问题，不应回滚已完成的还原。请记录警告并让流程继续。

修正快照组回滚的删除方式
VolumeSnapshotGroupRefVO 会通过外键级联删除。SystemTagVO 则依赖 ResourceVO 的级联删除。当前 SQL 仅删除 VolumeSnapshotGroupVO 记录，不会删除对应的 ResourceVO，因此 BackupTpmEncryptionKeyMsg 失败后，WITH_TPM 系统标签会残留。使用 dbf.removeByPrimaryKey(resourceUuid, VolumeSnapshotGroupVO.class)，确保标签与引用记录都被清理。

For vTPM live migration precheck, resolve libvirt secret UUID from source VM domain XML via agent and use that UUID to define destination host secret. Fail fast when UUID cannot be resolved, and add best-effort cleanup of destination secret on migration failure. Resolves: ZSV-11963 Change-Id: I73687962636e7871626e687761626d6661717778

Add a "sync-vm-host-files-before-migration" flow step before "prepare-nvram-folder-on-dest-host" in prepareNvRamBeforeMigration. When all VmHostFileVO.changeDate are null, skip the sync since files are already clean. Otherwise send SyncVmHostFilesFromHostMsg to ensure host files are up-to-date before migration proceeds. Resolves: ZSV-11882 Related: ZSV-11310 Change-Id: I7471676178747a7a6b79676e6e786a66646b7871 (cherry picked from commit 54d97ce)

Extract listVmHostFilesToSync() from syncVmHostFiles() to also include stopped VM host files on the last host when changeDate is set (dirty). This ensures pending host-side changes are synced back even after the VM is stopped. Resolves: ZSV-11779 Related: ZSV-11310 Change-Id: I686c726b6d756378666f63737a6965637a6c6d79 (cherry picked from commit 973ed5c)
When vmHostFile has a non-null changeDate, it indicates a pending change on the host that has not been synced back. In this case, the cached content on the management node may be stale and should not be used. Add a check to fail early with an error before using the cached content.

Add CascadeConstant.VM_INSTANCE_EXPUNGE_CODE and wire VM expunge to run TPM / VmHostFile / VmHostBackupFile cleanup via asyncCascade after volume/metadata flows, implemented as VmExpungeVmResourceCascadeFlow (VmAfterExpunge + snapshot tpm uuid + cascade). VmInstanceBase.expunge done handler now only loads tpm uuid from flow chain data and finishes DB removal. Defer TPM/host-file/backup-file cascade deletion when VmDeletionPolicy is Delay or Never so recycle-bin destroy keeps rows until APIExpungeVmInstanceMsg. Register the new flow last in expungeVmWorkFlowElements (VmInstanceManager.xml). Resolves: ZSV-12140 Change-Id: I6f736b6e647a636964636d6173626362796c6768 (cherry picked from commit 587137b)
