All,
is it possible to create a new KVM machine from an existing qcow (v3)

virt-manager 1:1.5.1-0ubuntu1.1 to create the machine.

------------------------------------------------------------
Currently we don't support so-called 'snapshots without (libvirt)
metadata'. We do support though creation of the metadata in libvirt
without actually invoking any qemu command.
You can use virsh snapshot-create --redefine flag for it. The snapshot
XML needs to have the same name as the qcow2 image's name.
Note that some stuff might not work properly if you don't add a domain
state XML which describes the hardware at the time the snapshot was
taken. (A workaround would be to create a snapshot with the desired
configuration with libvirt, then dump it and modify the name).
