Bug Description

== SRU Justification ==
The brd module (Rados block device) is essential for Ceph. But it's
not available in any of our KVM kernels for the moment.

== Fix ==
Change CONFIG_BLK_DEV_RBD from not set to "m" to solve this issue.

== Test ==
Test kernel for G-kvm could be found here:
https://people.canonical.com/~phlin/kernel/lp-1902434-rbd/

The rbd module can be loaded without any issue with this kernel:
$ sudo modprobe rbd
$ echo $?
0

[ 42.853540] Key type ceph registered
[ 42.853663] libceph: loaded (mon/osd proto 15/24)
[ 42.857811] rbd: loaded (major 252)

== Regression Potential ==
Low, this just make the rbd module available in our KVM kernels.
We might be receiving some rbd related issues in the future.

== Original Bug Report ==
The rbd module is missing from the linux-modules-*-kvm package

ubuntu@ubuntu:~$ modprobe rbd
modprobe: FATAL: Module rbd not found in directory /lib/modules/5.8.0-1008-kvm

I don't believe I can get this module from any of the other extra packages ie: linux-image-extra-virtual as it is the wrong kernel version and there is currently no extra's package for kvm.

As a work around I am using the generic image but it would be great to get this added to the kvm optimized image as well!

Hello,
Can you give this Groovy KVM kernel a try?
