I'd like to be able to move a bunch of instances from a Xen cluster
to a KVM cluster.

/usr/lib/ganeti/tools/move-instance tells me
OpPrereqError: ('Selected hypervisor (xen-pvm) not enabled in the cluster (kvm)', 'wrong_state')

It would be nice if it would either do the conversion for me or just
do what it can and then let me tweak the final bits manually.

Hi,

While we don't support this natively, there is a hack/workaround:

- "gnt-backup export" the instances
- edit the config file and replace the hypervisor entry
- "gnt-backup import" with the new hypervisor

The reason we don't have this automated right now is that we don't have
a way to "map" hypervisor parameters from one hypervisor to another…

Thanks for the report, this should/will be forwarded upstream.
