[one-users] Ubuntu shutdown/image save

Thu May 17 12:59:03 PDT 2012

what i meant as "catch" was just running a "ps -aux" on the host running
your vm to see what the command is doing

the qcow2 driver uses "qemu-img convert" to save the snapshot of your
running VM back to the datastore

How are you sharing the datastore?
