...consistent snapshotting or shall I > rely on QEMU backup new feature only? 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 ign...

Hi, Has anyone met the same problem that virsh hangs when there are some backup jobs running on the kvm host? I use dirty bitmap supported by qemu to do backups every 6 minitues. About a few hours later, I ran 'virsh list', It hung. Then I stopped the backup jobs ?nothing was getting better. I had checked the libvirt logs ?but found nothing useful . Maybe the high I/O caused the
