OK, in that case I'll just run paravirtualised machines in the mean
time.  I'm sure the performance is supposed to be very similar between
paravirt + hardware virt - can anyone confirm?

Yeah, thought so, just making sure that when using Xen it was *only*
paravirtualised - hence I tried the non-xen kernel

Attached is a snip from my xend.log.  The issue is actually caused by
the following error initially I suspect:

[2007-10-04 17:05:44 2504] DEBUG (XendDomain:960) Creating new managed 
domain: vps3
[2007-10-04 17:05:48 2504] WARNING (XendDomainInfo:1114) Domain has 
crashed: name=vps3 id=19.
[2007-10-04 17:05:48 2504] DEBUG (XendDomainInfo:1709) 
XendDomainInfo.destroy: domid=19

I then get the original error i mentioned when i try to start the domain 
manually.

Excellent, thanks for that :)  Will this be rolled out to the Fedora 7 
repos, or is it probably going to be more of an 8 thing?

Are you actually on holiday and working btw Michael?  If so, even more 
thanks are in order.
