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,
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?

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.
----> agent log-- libvirt: XML-RPC error : Cannot write data: Broken
pipe
03/09/2015 13:13:15 4882 jsvc.exec error: Service exit with a return
value of 143
Please let us know the exact steps to add Ceph KVM host to cloudstack.
Thanks,
Pradeep
