Now that we are trying to reboot some machines, the management server is giving us this error, like it is looking for a downed host, what alternative do I have to avoid this behavior and start the machines? 2023-05-01 13:00:04,675 DEBUG [c.c.d.DeploymentPlanningManagerImpl] (API-Job-Executor-2:ctx-4a417809 job-67468 ctx-6607eb32) (logid:a8eb35d8) Adding pods to avoid lists for non-explicit VM deployment: [] 2023-05-01 13:00:04,675 DEBUG [c.c.d.DeploymentPlanningManagerImpl] (API-Job-Executor-2:ctx-4a417809 job-67468 ctx-6607eb32) (logid:a8eb35d8) Adding clusters to avoid lists for non-explicit VM deployment: [] 2023-05-01 13:00:04,675 DEBUG [c.c.d.DeploymentPlanningManagerImpl] (API-Job-Executor-2:ctx-4a417809 job-67468 ctx-6607eb32) (logid:a8eb35d8) Adding hosts to avoid lists for non-explicit VM deployment: [] 2023-05-01 13:00:04,675 DEBUG [c.c.d.DeploymentPlanningManagerImpl] (API-Job-Executor-2:ctx-4a417809 job-67468 ctx-6607eb32) (logid:a8eb35d8) DeploymentPlanner allocation algorithm: null 2023-05-01 13:00:04,675 DEBUG [c.c.d.DeploymentPlanningManagerImpl] (API-Job-Executor-2:ctx-4a417809 job-67468 ctx-6607eb32) (logid:a8eb35d8) Trying to allocate a host and storage pools from dc:1, pod:null,cluster:null, requested cpu: 4800, requested ram: (4.00 GB) 4294967296 2023-05-01 13:00:04,675 DEBUG [c.c.d.DeploymentPlanningManagerImpl] (API-Job-Executor-2:ctx-4a417809 job-67468 ctx-6607eb32) (logid:a8eb35d8) Is ROOT volume READY (pool already allocated)?: Yes 2023-05-01 13:00:04,678 DEBUG [c.c.d.DeploymentPlanningManagerImpl] (API-Job-Executor-2:ctx-4a417809 job-67468 ctx-6607eb32) (logid:a8eb35d8) Deploy avoids pods: [], clusters: [], hosts: [] 2023-05-01 13:00:04,678 DEBUG [c.c.d.DeploymentPlanningManagerImpl] (API-Job-Executor-2:ctx-4a417809 job-67468 ctx-6607eb32) (logid:a8eb35d8) Deploy hosts with priorities {} , hosts have NORMAL priority by default 2023-05-01 13:00:04,678 DEBUG [c.c.d.DeploymentPlanningManagerImpl] (API-Job-Executor-2:ctx-4a417809 job-67468 ctx-6607eb32) (logid:a8eb35d8) This VM has last host_id specified, trying to choose the same host: 9 2023-05-01 13:00:04,682 ERROR [c.c.a.ApiAsyncJobDispatcher] (API-Job-Executor-2:ctx-4a417809 job-67468) (logid:a8eb35d8) Unexpected exception while executing org.apache.cloudstack.api.command.admin.vm.StartVMCmdByAdmin
