According to: http://wiki.libvirt.org/page/Snapshots virDomainSnapshotCreateXML is only consistent if the guest is paused during the operation. The new qemu feature is called drive-backup (http://wiki.qemu.org/Features/IncrementalBackup). Unless things changed recently, it is not exposed through libvirt, so the only way to use it is by sending qemu monitor commands (http://kashyapc.com/2013/03/31/multiple-ways-to-access-qemu-monitor-protocol-qmp/). This is all pretty bleeding edge. I still think you'd be better off just ignoring snapshots that fail and moving on to the next one.
