Hi, all! We are using VMWareVCDriver for our grizzly deployment. Cluster within 4 ESXi nodes is managed by OpenStack.
I've found here <https://wiki.openstack.org/wiki/HypervisorSupportMatrix>that ESX/VC drivers supports live-migration, also i found related method in code, it uses vmware API "MigrateVM_Task" function. But i couldn't understand how i should use live-migration: - standalone ESXi hosts not supports any migration. Therefore VMWareESXDriver also not supports migration. Correct, if am wrong. - In case vCenter (VMWareVCDriver) i could use vMotion to migrate VMs between members of cluster. But nova sees cluster as a single "host" and thru "nova live-migration VM" scheduler raise exception "NoValidHost: No valid host was found." My question is: What is the use-case of this<https://github.com/openstack/nova/blob/stable/grizzly/nova/virt/vmwareapi/vmops.py#L1018>function ? -- Regards, Roman Sokolkov
