Vadim,
afaik you are right for mgmt server. As for KVM nodes - libvirt and
qemu/qemu-img in CentOS6.x does NOT have RBD support at all :) I have
not
played a lot with CentOS7, but did quick check long time ago and I
thing it
also doesnt support RBD - Red Hat wants you to buy RHEV to support RBD
- of
course, there are workarround, self-compile libvirt etc...similar for
qemu/qemu-img.
I know for sure that Ubuntu 14.x suports RBD out of the box - since we
are
running it with CEPH.

Andrija,
Are you talking about CS Management server OS? I thought it does
not really matter if it includes libvirt or not. All calls to storage
should go through hypervisor and any KVM host goes with libvirt. The
version of libvirt for old OS may not be aligned with latest Ceph
release
that is true. Cloud architect must check compatibility version matrix
for
all products Ceph/KVM/CS anyway.
Vadim.

RBD for KVM comes out of the box for Ubuntu 14.x (perhaps also 12.x) -
not with CentOS6, and not sure really about CentOS7 (probably not
also...)

Ceph
(RBD) storage type is not yet implemented. I would say it is very
hypervisor-specific and does not depend much from Cloudstack.

I have one question:
Is ceph rbd protocol supported by default on libvirt version
0.10.2-54.el6.x86_64 OR do we need to compile libvirt to support rbd
within
cloudstack.

Pradeep

Pradeep,
I have installed CS 4.2 with Ceph storage successfully around year ago.
There were no problem with configuration except the fact that you can't
configure RBD storage as primary storage during Zone set-up.
It must be NFS.
After Zone is set-up and running you may add another primary storage
and
there you have list of choices where RBD type is present.
After RBD is added you may assign this as default storage for
particular
cluster assuming that each cluster has its own primary storage.
PS. I have also used Ceph object gateway to connect secondary storage.
It
works as expected. It would be nice to know which way are you going to
integrate Ceph into CS?
Vadim.

We are well aware of the best practices/recommendations for cloudstack.

Pradeep,
From documentation :
Warning -- It is NOT recommended to run services on this host not
controlled by CloudStack.
Good practice -- KVM host must be virgin-clean.

Hello Vadim,
We have followed the same guide and using OVS version 2.3.2 .
Ceph storage cluster is running on same KVM hypervisor and it fails
when adding to cloudstack.

Hello Shetty,
It seems you agent or libvirt configuration is wrong. Please, specify
also do you use OVS or Linux bridge?
Did you follow this guide?

Hello Folks,
We are working on ceph(hammer, 0.94.3) implementation on kvm
hypervisor(centos 6.5) which will be integrated on cloudstack(4.4.2),
--- Single KVM node( OS- CentOS 6.5, libvirt-0.10.2-54.el6.x86_64,
openvswitch 2.3.2) + ceph hammer, cluster health is Ok.
We are unable to add the KVM host(new cluster) in cloudstack in an
existing zone, below is the error log.

Please let us know the exact steps to add Ceph KVM host to cloudstack.
Thanks,
