Hi Everyone,
I'm trying to start a domain that will discard all changes to its disks on
shutdown. I've tried adding <transient/> to the disk declarations in the
definition xml but this results in a "not supported" error message on
define. Is there a way to do this without creating and rolling back
snapshots?
Thanks,
Jason

Not yet - manually running snapshots or using qemu-img to create your
own wrappers is indeed your only option at the moment. But adding
<transient> support is on my list sometime in the next few months:
