While I realize you want to trivially clone VMs with some state at random point in time, you might want to look into `virt-builder` about cloning VMs. It has some sensible advice: http://libguestfs.org/virt-builder.1.html#clones Using `virt-builder` to clone images, will 'sysprep' the images, which will ensure that (a) each VM copy gets a fresh pair of SSH host keys; (b) a new random seed; (c) all security/sensitive information is removed; (d) log files are cleaned (in the below URL, look up the string "logfiles *" to see what all it removes), and much more. Take a look here for what all it does: http://libguestfs.org/virt-sysprep.1.html#operations http://libguestfs.org/virt-sysprep.1.html#security > Tried with virt-manager and with virsh but so far it seems like this > case is not supported by these tools.

With 'virsh', you _can_ save the live disk and memory state: $ virsh snapshot-create-as \ --domain myvm snap1 \ --diskspec vda,file=./disk-snap.qcow2,snapshot=external \ --memspec file=./mem-snap.qcow2,snapshot=external \ --atomic -- /kashyap
