Re: centos6.4 + libvirt + qemu + rbd/ceph

[John Kinsella <jlk@xxxxxxxxxxxx>]

Will throw my US $0.02 in here...

We’re running CentOS 6.4[1] + modern Ceph, VMs are managed by CloudStack. We use distro packages whenever possible - most times folks suggest building something from source, I have to be dragged kicking and screaming to agreement.

Ceph support is one of the very few exceptions. We build/package/sign modern kernels (3.6.11), modern libvirt (0.9.13), modern qemu (1.2.0) and probably a few other bits. The improved functionality is easily worth the effort.

1:Due to RH Cloud agreements we’ll have to run RHEL hypervisors soon, will be happy to share thoughts on getting Ceph working with that once we do it

Wido, we were thinking along that line as well.  We're trying to figure out which path will cause the least amount of pain ;)

Is there any way to make the creation process better?  We are hoping to
be able to use a virsh pool using the rbd driver but it appears that
Redhat has not compiled libvirt with rbd support.

Thought?

Recompile libvirt? Since RedHat hasn't enabled the RBD support in libvirt that's your problem.

Might be that they'll do it in RHEL 7 where librbd is available natively?

Thanks,
