I'm not sure about your deployment, but i noticed that when i try to resize
a vm nova also tries to move the vm to another compute-node, so if you
don't have a shared storage for the VMs this is not possible (unless your
compute-node can ssh to the other compute-node ofcourse). I found in my
logs thigs like "*ssh root at node2 mkdir -p
/var/lib/nova/instances/instances_dir"* when trying to resize a VM.
Tomorrow i'll trying resizing with shared storage and i'll let you know.
