[ovirt-users] Hosted Engine not responding

I'm pretty sure that I've got a failing (to boot) kernel on my Self hosted engine, as this has happened a few times on 'regular' guest VM's I've tried getting it to boot from (several) CD Image, but there is no VNC console and hosted-engine --console just hangs at Escape character is ^] Any suggestions ? I know which LVM is the hosted engine disk but I don't know how to mount it from the physical host, If I could mount it I could probably switch the kernel back to an earlier one. All else fails I have a back up of the engine taken this morning, but I seem to recall having problems re-deploying hosted-engine when one already exists in the cluster (dead or not) Regards, Brett
