Thanks for the report. To be perfectly honest, I can't see how what happened could happen :). But I'll take a closer look at it and see if I can reproduce and see what is going on with it.
I see thread locking problems in the code - qemuDomainSnapshotCreateXML() is calling monitor commands, but has not run qemuDomainObjBeginJobWithDriver() to ensure exclusive access to the monitor - qemuDomainSnapshotDiscard has same problem Daniel -- |: Red Hat, Engineering, London -o- http://people.redhat.com/berrange/ :| |: http://libvirt.org -o- http://virt-manager.org -o- http://deltacloud.org :| |: http://autobuild.org -o- http://search.cpan.org/~danberr/ :| |: GnuPG: 7D3B9505 -o- F3C9 553F A1DA 4AC2 5648 23C1 B3DF F742 7D3B 9505 :|
