Comment 1 for bug 1036973

Thanks for submitting this bug.

I can't reproduce this. There is an oddity in the bug description, in that you
use the same name for the domain and the snapshot. When I use 'p1-clone' for
both the domain and snapshot name (as you did), then I need to revert using

 virsh snapshot-revert p1-clone --snapshotname p1-clone

If I simply try

 virsh snapshot-revert p1-clone

I get

 error: --snapshotname or --current is required

which is not the same error you show. (The .xml I used was

<domainsnapshot>
    <name>p1-clone</name>
    <description> p1 clone base snapshot </description>
</domainsnapshot>

and I defined it, for domain p1-clone, using

 virsh snapshot-create p1-clone snapshot-p1-clone2.xml
)

I've marked this bug as affecting libvirt. Please do

 apport-collect 1036973

to have apport submit some information about your libvirt installation.

I'd highly recommend working around this by using a snapshot name which
is not the same as the domain name. If that doesn't work either, please
reply and let us know.
