InvalidSharedStorage_Remote: ymy-r1-7 is not on shared storage: Live migration
can not be used without s
hared storage.
======================================================
I use only one rbd storage pool for my instances. There are shared
storage actually. But the code in nova for checking shared storage do
not make sence for rbd image backend.
