> When VM is live migrated to a different host , stopped and started , It starts on the original host where it was before live migration
> Steps to reproduce the problem:
> Deploy a Vm.
> Say it gets deployed on host1 ( in my case host id 9)
> Live migrate the Vm to a different host say host2 in the same cluster ( in my case host id 7).
> After live migration , stop this VM.
> Start this VM.
> We expect the Vm to be started on 7.
> Actual Behavior:
> Vm is started on 9 , since the "last_host_id" for the Vm still point to "9". last_host_id did not change when the Vm was migrated and also when the Vm was stopped.
> After deployment succeeds:
> mysql> select id, uuid,host_id,last_host_id,state,name from vm_instance where id in (56) and state not in ("Expunging");
