But in the kilo release, if I do a single node devstack installation there is block and live migration. So how is that possible?
As a single-node installation has only 1 compute host so where would the VM get migrated ?

I belive this can be possible by setting the allow_resize_same_host. More details can be found here: http://www.madorn.com/resize-on-single-compute.html . I believe the issue Dave is talking about is specifically targeting the same host for resize assuming the host can support it in a milti-node setup. As getting the scheduler to choose the current host in the multihost setup is 95 percent of the battle.

No. Providing a mechanism for this is discussed from time to time, but it is not currently available.
