Hi,

virsh has save/restore to do a one-time save+shutdown. But it does not expose kvm's savevm/restorevm, which let's me do incremental snapshots. Is there a specific reason why that is not exposed in libvirt, or is it just that noone has implemented it?

The save/restore API only does a memory snapshot. If you are referring to the savevm/loadvm/delvm, which take a disk+memory snapshot, then that is implemented in terms of the libvirt snapshot API.
