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 -----Original Message----- From: Gnan Kumar, Yalla Sent: Wednesday, February 19, 2014 11:15 AM To: 'Alfredo Deza'; ceph-users@xxxxxxxxxxxxxx Cc: ceph-users@xxxxxxxxxxxxxx Subject: RE: Unable to add monitor nodes 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 ?
