Sorry was not precise enough with my previous email. Does not seem to be 
Koan that is crashing it just appears to be having a problem creating 
the virtual machine, i.e. if I go into virsh I have a machine there I 
can connect to via console <machine name>. Although the machine is stuck 
on boot see below:-

*_Also the tail end of the /var/log/messages log just in case this is 
useful:-

*_Interesting thing is I can create a VM fine manually with virt-install?

Would be great if you could help out with this.

Many thanks,
