This exactly patch set probably not, no.

You can do this now already? This patchset is for migrations of VMs 
between two separate Clusters
(i.e. useful to move a VM from testing to production)

Migration between nodes in the same cluster with no shared storage can 
be already achieved,

Directly migrating in via WebUI is not yet exposed, AFAIK, but on the 
CLI you may try to use


qm migrate <vmid> <target-node> -oneline -with-local-disks

-oneline flag is needed in general for oneline live migration and 
additional the
-with-local-disks is needed to mirroring local disks over.

Should work with latest Proxmox VE 4.4

cheers,
Thomas
