OpenStack Compute (nova)

Live Snapshot VMs

Registered by Vish Ishaya

The snapshot command takes a cold snapshot of the instance disk. There are some use cases where it is useful to be able to snapshot the memory and processor state as well to be able to do a quick-launch of the instance. Note that booting from this
special type of snapshot can be tricky, as the guest will need to reconfigure some things like its ip.
