### Description This PR allows config drive deletion of migrated VM, on host maintenance (from it's last source location - host cache/primary/secondary storage). Fixes below issues identified during host maintenance tests, with VM using config drive on KVM host cache. 1. Old config drive location is overriden in the VM detail, while creating the new one during the migration (config drive location would change here, in case any of the location settings updated after VM is created - vm.configdrive.force.host.cache.use, vm.configdrive.primarypool.enabled, vm.configdrive.use.host.cache.on.unsupported.pool). If so, the rollback or post migration tries to delete the config drive from the new/overriden location in the source host after migration, where the file doesn't exists. 1. Delete config drive command HandleConfigDriveIsoCommand is not allowed when host is in maintenance. ``` 2024-12-04 07:36:10,315 DEBUG [c.c.n.e.ConfigDriveNetworkElement] (Work-Job-Executor-10:ctx-fabb0d27 job-58/job-60 ctx-43e67e9c) (logid:332edac0) Deleting config drive ISO for vm: i-2-6-VM on host: 1 2024-12-04 07:36:10,318 WARN [c.c.a.m.AgentManagerImpl] (Work-Job-Executor-10:ctx-fabb0d27 job-58/job-60 ctx-43e67e9c) (logid:332edac0) Resource [Host:1] is unreachable: Host 1: Unable to send class com.cloud.agent.api.HandleConfigDriveIsoCommand because agent ol8.localdomain is in maintenance mode 2024-12-04 07:36:10,319 ERROR [c.c.v.VmWorkJobHandlerProxy] (Work-Job-Executor-10:ctx-fabb0d27 job-58/job-60 ctx-43e67e9c) (logid:332edac0) Invocation exception, caused by: com.cloud.utils.exception.CloudRuntimeException: Unable to get an answer to handle config drive deletion for vm: i-2-6-VM on host: 1 2024-12-04 07:36:10,319 INFO [c.c.v.VmWorkJobHandlerProxy] (Work-Job-Executor-10:ctx-fabb0d27 job-58/job-60 ctx-43e67e9c) (logid:332edac0) Rethrow exception com.cloud.utils.exception.CloudRuntimeException: Unable to get an answer to handle config drive deletion for vm: i-2-6-VM on host: 1 2024-12-04 07:36:10,319 DEBUG [c.c.v.VmWorkJobDispatcher] (Work-Job-Executor-10:ctx-fabb0d27 job-58/job-60) (logid:332edac0) Done with run of VM work job: com.cloud.vm.VmWorkMigrateAway for VM 6, job origin: 58 2024-12-04 07:36:10,319 ERROR [c.c.v.VmWorkJobDispatcher] (Work-Job-Executor-10:ctx-fabb0d27 job-58/job-60) (logid:332edac0) Unable to complete AsyncJobVO: {id:60, userId: 1, accountId: 1, instanceType: null, instanceId: null, cmd: com.cloud.vm.VmWorkMigrateAway, cmdInfo: rO0ABXNyAB5jb20uY2xvdWQudm0uVm1Xb3JrTWlncmF0ZUF3YXmt4MX4jtcEmwIAAUoACXNyY0hvc3RJZHhyABNjb20uY2xvdWQudm0uVm1Xb3Jrn5m2VvAlZ2sCAARKAAlhY2NvdW50SWRKAAZ1c2VySWRKAAR2bUlkTAALaGFuZGxlck5hbWV0ABJMamF2YS9sYW5nL1N0cmluZzt4cAAAAAAAAAABAAAAAAAAAAEAAAAAAAAABnQAGVZpcnR1YWxNYWNoaW5lTWFuYWdlckltcGwAAAAAAAAAAQ, cmdVersion: 0, status: IN_PROGRESS, processStatus: 0, resultCode: 0, result: null, initMsid: 32986187695067, completeMsid: null, lastUpdated: null, lastPolled: null, created: Wed Dec 04 07:36:04 UTC 2024, removed: null}, job origin:58 com.cloud.utils.exception.CloudRuntimeException: Unable to get an answer to handle config drive deletion for vm: i-2-6-VM on host: 1 at com.cloud.network.element.ConfigDriveNetworkElement.deleteConfigDriveIsoOnHostCache(ConfigDriveNetworkElement.java:585) at com.cloud.network.element.ConfigDriveNetworkElement.commitMigration(ConfigDriveNetworkElement.java:379) at org.apache.cloudstack.engine.orchestration.NetworkOrchestrator.commitNicForMigration(NetworkOrchestrator.java:2264) at com.cloud.vm.VirtualMachineManagerImpl.migrate(VirtualMachineManagerImpl.java:2904) at com.cloud.vm.VirtualMachineManagerImpl.orchestrateMigrateAway(VirtualMachineManagerImpl.java:3488) at com.cloud.vm.VirtualMachineManagerImpl.orchestrateMigrateAway(VirtualMachineManagerImpl.java:5535) ``` <!--- Describe your changes in DETAIL - And how has behaviour functionally changed. --> <!-- For new features, provide link to FS, dev ML discussion etc. --> <!-- In case of bug fix, the expected and actual behaviours, steps to reproduce. --> <!-- When "Fixes: #<id>" is specified, the issue/PR will automatically be closed when this PR gets merged --> <!-- For addressing multiple issues/PRs, use multiple "Fixes: #<id>" --> <!-- Fixes: # --> <!--- ******************************************************************************* --> <!--- NOTE: AUTOMATION USES THE DESCRIPTIONS TO SET LABELS AND PRODUCE DOCUMENTATION. --> <!--- PLEASE PUT AN 'X' in only **ONE** box --> <!--- ******************************************************************************* --> ### Types of changes - [ ] Breaking change (fix or feature that would cause existing functionality to change) - [ ] New feature (non-breaking change which adds functionality) - [x] Bug fix (non-breaking change which fixes an issue) - [ ] Enhancement (improves an existing feature and functionality) - [ ] Cleanup (Code refactoring and cleanup, that may add test cases) - [ ] build/CI - [ ] test (unit or integration test code) ### Feature/Enhancement Scale or Bug Severity #### Feature/Enhancement Scale - [ ] Major - [ ] Minor #### Bug Severity - [ ] BLOCKER - [ ] Critical - [x] Major - [ ] Minor - [ ] Trivial ### Screenshots (if appropriate): ### How Has This Been Tested?
