thanks for help.. I did again ,and I collected new logs: My vm_instance name is i-2-39-VM. There was some routers in KVM host 'A' (this one that I powered off now): [root@1q2 ~]# grep -i -E 'SimpleInvestigator.*false' /var/log/cloudstack/management/catalina.out INFO [c.c.h.HighAvailabilityManagerImpl] (HA-Worker-2:ctx-e2f91c9c work-3) SimpleInvestigator found VM[DomainRouter|r-4-VM]to be alive? false INFO [c.c.h.HighAvailabilityManagerImpl] (HA-Worker-1:ctx-729acf4f work-7) SimpleInvestigator found VM[User|i-23-33-VM]to be alive? false INFO [c.c.h.HighAvailabilityManagerImpl] (HA-Worker-4:ctx-a66a4941 work-8) SimpleInvestigator found VM[DomainRouter|r-36-VM]to be alive? false INFO [c.c.h.HighAvailabilityManagerImpl] (HA-Worker-1:ctx-5977245e work-10) SimpleInvestigator found VM[User|i-17-26-VM]to be alive? false INFO [c.c.h.HighAvailabilityManagerImpl] (HA-Worker-1:ctx-c7f39be0 work-9) SimpleInvestigator found VM[DomainRouter|r-32-VM]to be alive? false INFO [c.c.h.HighAvailabilityManagerImpl] (HA-Worker-3:ctx-ad4f5fda work-10) SimpleInvestigator found VM[DomainRouter|r-46-VM]to be alive? false INFO [c.c.h.HighAvailabilityManagerImpl] (HA-Worker-0:ctx-0257f5af work-11) SimpleInvestigator found VM[User|i-4-52-VM]to be alive? false INFO [c.c.h.HighAvailabilityManagerImpl] (HA-Worker-4:ctx-7ddff382 work-12) SimpleInvestigator found VM[DomainRouter|r-32-VM]to be alive? false INFO [c.c.h.HighAvailabilityManagerImpl] (HA-Worker-1:ctx-9f79917e work-13) SimpleInvestigator found VM[User|i-2-39-VM]to be alive? false KVM host 'B' agent log (where the machine would be migrate): 2015-07-16 16:58:56,537 INFO [kvm.resource.LibvirtComputingResource] (agentRequest-Handler-4:null) Live migration of instance i-2-39-VM initiated 2015-07-16 16:58:57,540 INFO [kvm.resource.LibvirtComputingResource] (agentRequest-Handler-4:null) Waiting for migration of i-2-39-VM to complete, waited 1000ms 2015-07-16 16:58:58,541 INFO [kvm.resource.LibvirtComputingResource] (agentRequest-Handler-4:null) Waiting for migration of i-2-39-VM to complete, waited 2000ms 2015-07-16 16:58:59,542 INFO [kvm.resource.LibvirtComputingResource] (agentRequest-Handler-4:null) Waiting for migration of i-2-39-VM to complete, waited 3000ms 2015-07-16 16:59:00,543 INFO [kvm.resource.LibvirtComputingResource] (agentRequest-Handler-4:null) Waiting for migration of i-2-39-VM to complete, waited 4000ms 2015-07-16 16:59:01,245 INFO [kvm.resource.LibvirtComputingResource] (agentRequest-Handler-4:null) Migration thread for i-2-39-VM is done It said done for my i-2-39-VM instance, but I canĀ“t ping this host.
