It doesn't run any ceph services, but I do use it to monitor and troubleshoot the cluster. It is connected to the ceph public network (which is a non-routable network) and to my corporate network. Most of the ceph cluster is not on the corporate network, so I use this VM as a jumpbox to get into the rest of the network. I use the same OS (Ubuntu 12.04) on the deploy VM as all my other ceph servers/VMs. This is nice so I can test new packages and kernels on this VM first. That way I don't take down the ceph cluster when a kernel upgrade goes bad. I just tested 3.18rc2 and found it made my VM unbootable. Jake
