I created a VM, and started it in stateless mode. Then I shut it down, and I can not started it again...

I got an error like this on starting it: Failed to start VM st1, because exist snapshot for stateless state. Snapshot will be deleted.

the error in the log is a bug. when the vm is shut down the snapshot should be deleted automatically and if we fail to delete it the next time you try to run the vm it should be deleted. from the thread you attached, we have an error with a NullPointerException on the restore which is a bug. what rhevm version are you using? (is it the most current one?) does it happen with every vm or just this one? is the snapshot created from template? And the stateless snapshot should be read-only so that's fine.

By the way, in the snapshot tab, the stateless snapshot was read-only. Is this correct? _______________________________________________ Users mailing list Users@ovirt.org http://lists.ovirt.org/mailman/listinfo/users

Thanks, I'm using fedora18 with latest updates and ovirt from latest source code. And I've tried five or six VMs created from the same template. Should I try making another template or what?
