Hi again,
I've had a look at the qemu-kvm SRPM and RBD is intentionally disabled
in the RHEL 7.0 release packages. There's a block in the .spec file that
reads:
%if %{rhev}
--enable-live-block-ops \
--enable-ceph-support \
%else
--disable-live-block-ops \
--disable-ceph-support \
%endif
rhev is defined 0 at the top of the file, setting this to 1 and
rebuilding after sorting the build dependencies yields some new packages
with RBD support and a -rhev suffix that install and work on RHEL 7.0
just fine. I tested with a KVM VM using RBD/cephx storage via
libvirt/qemu directly. As I was using virtio-scsi, TRIM also worked.
iasl was the only build requirement I wasn't able to satisfy so I
commented it out (the comments state that it's not a hard requirement).
This doesn't seem to have had any ill effects for me.
To avoid the -rhev suffix I ultimately made the attached changes to the
spec file before rebuilding them for myself.
Cheers,
Simon

Hi,
Is there going to be ceph-extras repos for rhel7?
Unless I'm very much mistaken I think the RHEL 7.0 release qemu-kvm
packages don't support RBD.
Cheers,
Simon.
