Hello,

Following the issue #162, I have implemented the capability to handle multiple Ceph RBD Pool by using a comma-separated list on the ceph.conf file.

Regarding the Libvirt documentation, the host tag must be in the source tag and not after. I have fix them also.

I have also implemented the tests to handle the Ceph part by using a mock of the File object.

Feel free if you have questions

I'd prefer to fix this up in read_ceph_args so you don't do this in a loop. Same below for the monitor. Perhaps also add in .map(&:strip) so you can also use spaces between the values while you're at it.

Another thing is that libvirt_ceph_pools suggests it's singular while so perhaps store the result of that as libvirt_ceph_pools to indicate it's an array?

Ok ! I have updated the branch to move the split and verify keys in the read_ceph_args.

I merged this separate so it properly closed the issue. Doing 2 different things (fixing a bug and adding a new feature) in the same commit is something I prefer to avoid.

Ok, I haven't seen the fix when I have started to work on it. I will rebase the merge on it.
