Deleting/Removing fully virtualised Xen Guest

Halt/shutdown the Xen Guest/Virtual Machine to be decommissioned. This should 'power' it down. On a Linux Guest console (not the host) use shutdown -h now for a Linux system or, for a Windows system, RDP and shutdown the machine.
SSH into the Dom0 (the host machine).
```
xm list | grep <DomU> 
```
where <DomU> is the short hostname of the virtual machine, e.g. yoyodyne. The DomU to be decommissioned should not be listed. If it is, execute
```
xm destroy <DomU> 
```
This command force shutdowns the VM
Remove the auto-boot symlink:
```
rm /etc/xen/auto/<DomU>.cfg 
```
Remove the Xen domain configuration:
```
rm /etc/xen/<DomU>.cfg 
```
Remove all logical volumes associated with the domU. In most cases this will consist of a single LV:
```
lvremove /dev/<Dom0>/<DomU>-<device> 
```
For example:
```
lvremove /dev/dom0server/yoyodyne.example.com-hda 
```
