Hi! >From my Ubuntu Desktop, I can easily access my OpenStack Compute nodes and its Instances with Virt-Manager... Also, from root user at your compute node, your probably can use the command "virsh edit instance-xxxxxxx" to add the CD...
My Hypervisors (Compute nodes) are based on Ubuntu 12.04 + KVM. I do not keep changing the Instances VM configurations using virt-manager, only from OpenStack Dashboard but, it is helpful when something gets wrong with a Instance, so, when this happens, add a CD to it, attach the sysrescuecd ISO, fix it, detach, remove the virtual CD drive and restart the Instance... I think that this procedure will not hurt your OpenStack but, would be nice to hear from someone more expert... =) If someone else says that this is bad, don't do it.
