Changes to Citrix XenServer is Trash between r0 and r1
'''Citrix XenServer is Trash -- DO NOT USE IT'''
Problems:
* Poor Linux distribution
* Poor disk support
* Doesn't support accessing specifying a local disk image
* Doesn't support specifying a local disk image
** Can't use a raw disk image, must be a VHD
** Conversion from raw disk image to VHD loses sparseness and causes XenServer to crash
This could all be avoided by using Xen with any non-crappy Linux distribution.
