Hi,
I have some existing QEMU images. Now I want to use it with
libvirt/virsh. Is there any easy way to do that?
I suppose that we need an XML file for each image, but dont want to
craft them from scratch.
Thanks,

There isn't really an official way to do this, but we will
probably add some explicit support for it to virt-install
or virt-manager down the line.
You can try something like this (obviously this is
dependent on your previous virt-install troubles being
fixed):
virt-install --name somename --ram 256 --vnc \
--hvm --accelerate \
--cdrom /some/existing/file \
--file /path/to/existing/image \
The vnc console should pop up, but if you just pointed to
some useless file for cdrom boot will fail (which is fine).
Just kill virt-install, run 'virsh destroy somename' (this
will hard poweroff the VM), and the VM should be good to
go for future runs.
