I have a QEMU image (qcow2) with a snapshot stored in it. Right now I'm using libvirt to start it.
However, I want to be able to run more than one instance of the same image+snapshot.
I guess I can do that by cloning the virtual-hd and installing/creating a new domain (virsh) and then running revert from snapshot. But I want to be able to do that pretty much "on-the-fly" with as little as possible latency from the time I decide I need to run another instance of image X to the time that instance is running from the stored snapshot. (I wan't to avoid writing to the hard-drive as possible)
Anyone did anything like that? I started thinking maybe libvirt is not low-level enough for this ?
