I do. Managing VM from libvrit works well for basic features. That beeing said, I had to manage snapshots outside of the provided features due to internal dependencies between qcow2 snapshots. I still have to test migration as it requires virtual disks shared over the network. > What is the most dynamic way of automatically setting up virtual > networks per VM? Should I use qemu-ifup? I think the best alternative is to use a dedicated virtual bridging tool but virt-manager (so, libvirt I guess) already provide a network system (based on tun/tap AFAIR). -- Nicolas Sebrecht
