Hi Jon,
It might be that your qemu-kvm version/build doesn't support lib{rados,rbd}.
Which Ganeti version are you using?

Hi,
I have a 3 node Ceph cluster to test, it's fully operationaly now.
I am now moving toward a virtual platform, and am first looking toward
Ganeti with KVM.
I have the Ganeti node and KVM configured, and from the node I can query
the Ceph cluster; ceph osd tree, ceph health, etc.
When attempting to create a VM though, I get the No such file or
directory error.

I have noticed this file.
root@hype-1:~# cat /sys/devices/rbd/1/name
2dde8ec6-f46c-40e9-b1b7-f5f8a653c42c.rbd.disk0
Which seems to fit the UUID, so just need to piece these bits together..
Thanks,
Jon
