Hi Karan,
Moreover my openstack setup consist of three nodes with three services each on all the nodes.
Controller node : Keystone, Nova service, Horizon
Compute node: Nova-compute, Glance and Cinder.
Neutron node: Mysql, RabbitMQ, Neutron service.
Thanks

Hi Karan,
Thank you very much for the reply.
Unfortunately I am unable to access the blogspot link. The second link deals with KVM in general.
But I have installed Havana openstack. Could you please send me the list of steps to configure
Openstack to use the rados block device both as a volume for the VM and also as a boot volume with cirrOS image in it.
Thanks
Kumar
Hi,
I want to implement two scenarios:
-------------------
1. Store the sample cirrOS image in ceph block device and use it to boot the VMs.
2. Use the ceph block device as a volume and attach it to the VMs.
Thanks
Kumar

Hi,
Now I am integrating ceph with openstack. I have installed openstack . Now to test ceph,
how do I create a ceph block device and store the sample cirrOS image in it and use it for booting VMs ?
Thanks
Kumar

ceph-deploy is not able to add new monitors, this is a feature that is actually being worked on at the moment
See http://tracker.ceph.com/issues/6638
You will need to do this manually and specify all the things you are missing following the Ceph docs here
http://ceph.com/docs/master/rados/operations/add-or-rm-mons/

Hi,
I am new user of ceph. I have installed a three node cluster following
the ceph document. I have added OSDs and initial monitor.
But while adding additional monitors, I am receiving this error as
