[Bug 442598] Re: 'qemu-img snapshot' crashed, corrupting disk image

[Dustin Kirkland]

Actually I tested savevm too, and that seems to work as well.  Here's
how, for completeness...

$ kvm-img create -f qcow2 foo.img 4G
Formatting 'foo.img', fmt=qcow2 size=4294967296 encryption=off cluster_size=0

$ kvm -m 512 -cdrom lucid-desktop-amd64.iso -hda foo.img

At some point here (even during boot), drop to monitor
ctrl-alt-2
savevm foo.img

You can watch the image grow as memory is written:
$ watch ls -alF foo.img

Once it's done, go back to the vga with ctrl-alt-1.  Change the system somehow.  Then roll back with
ctrl-alt-2
loadvm foo.img

Worked well for me.
