Ceph with foreman VMs?

Support
1

Hi,

I usually create VMs with foreman, but until now I was using a "standard" kvm/libvirt installation : I'd now like to try to deploy VMs which use ceph as a storage backend… can I do that with foreman (provided I define the correct pool in the libvirt hosts) ?

Thanks

Frederic

AFAIK I was using LVM pools for some time, there was a bug which was
fixed: Bug #2374: Libvirt host creation fails with LVM storage pool - Foreman

You might get another one, or not. Try it out and report.

Hi,

Almost one year later… I started using ceph yesterday with foreman.

For this to work, I had to tweak the fog library as explained here :
https://github.com/fog/fog/issues/3285

I hoped I could avoid having to deploy a ceph config on the foreman server and that I could tell foreman to create vms using something like this:
<source pool='blk-pool0' volume='blk-pool0-vol0'/>
instead of a " <source file=…" for the disks
(having defined a libvirt ceph pool)

But unfortunately, libvirt (on CentOS 7.2) does not support starting VMs with a "pool=… volume=…" using a rbd pool … that's just unimplemented, what a pitty.
VMs are correctly started/provisioned :]

Regards
