问题
I want to use python and the xenserver API to live migrate locally stored VM's, within a pool.
I am using the xenapi.VM.Pool_Migrate($vm, $host, $options) call and when I run it, the icon for the VM in XenCenter turns yellow for a moment, and the script exits cleanly, but the VM does not move.
I think this is because the VM is locally stored on the host. But I can manually migrate it to another host within XenCenter, so how do I do this in the API?
回答1:
This works for me.
Get the vm_ref and new_vm_host_ref
vm_ref = xenapi.VM.get_by_uuid(vm_uuid)
Now migrate with the live migration flag set as true
xenapi.VM.pool_migrate(vm_ref, new_vm_host_ref, {"live": "true"})
Though Xenserver is now free but the previous releases supports live migration only for the enterprise edition.
