I can see some info here :

- https://blueprints.launchpad.net/nova/+spec/kvm-block-migration
- https://blueprints.launchpad.net/nova/+spec/migrate-volume-block-migration


For underlying mechanics:

- Upstream QEMU has some related documentation --
http://wiki.qemu.org/Features/LiveBlockMigration

- Also, libvirt has a lot of block-layer work in progress (recent things include,
blockcopy, blockpull, blockcommit)


On a related note, I wrote some notes here on some of the libvirt block
operations/snapshots -- http://kashyapc.fedorapeople.org/virt/lc-2012/snapshots-handout.html

(However, it's a couple of months old, and few things have changed. I'm trying to revisit
it after testing with newest qemu/libvirt).


Hope that's helpful.
