I rebooted a VM on my Xenserver (over ssh to the vm) and it never came back up.

Going into xencenter shows that the VM is running but at 100% CPU Usage. If I try to access the guest console it just sits there with a black screen saying looking for guest console. I've left it for a good hour which is more than enough time for it to do any HDD checks it might want to, but it never appears on the network or drops its processor usage.

If I force restart it I can see from the console that it turns on and then hands over to the HDDs but nothing happens after that.

I am running XenSever 6.0

If I attach a live CD it will boot to the live OS and let me browse the HDD no problem so I don't know whats going on at all. – Arcath Aug 8 '12 at 14:49

What OS is the VM running? I have had many problems with Ubuntu as it is not virtualized properly in XenServer. Can you ping any IP's assigned to this VM? When you force restart it, are you certain it is actually being restarted? Does the console show the console booting? If not, try using the XenServer's console to kill the VM and any processes running and restart it. Also try starting on a different XenServer. – boburob Aug 8 '12 at 16:27
I only have one xenserver at the moment so I can't move it around. I am using ubuntu and I've found an article about ubuntu when using the other install media template so I will be looking into that, if it works I will answer the question with my results. – Arcath Aug 9 '12 at 6:55
