As for why qemu is seeing an EINVAL, I have to wonder if it is a case of AppArmor blocking access to a file. But that's weird, as internal snapshots don't normally need to open any additional files. At any rate, it's more likely to be a qemu bug than a libvirt one. -- Eric Blake eblake redhat com +1-919-301-3266 Libvirt virtualization library http://libvirt.org
