14 I do. Managing VM from libvrit works well for basic features. That
15 beeing said, I had to manage snapshots outside of the provided features
16 due to internal dependencies between qcow2 snapshots.
18 I still have to test migration as it requires virtual disks shared over
19 the network.

24 I think the best alternative is to use a dedicated virtual bridging
25 tool but virt-manager (so, libvirt I guess) already provide a network
26 system (based on tun/tap AFAIR).
