Deleting Virtual Machines

When you use Virtual Machine Manager or the xm command to delete a virtual machine, it no longer appears as a virtual machine, but its initial startup file and virtual disks are not automatically deleted.

To delete all components of a virtual machine configured with a file-backed virtual disk, you must manually delete its virtual disk image file (/var/lib/xen/images/) and its initial startup file (/etc/xen/vm).
