Also along the same line of recommendation - have you considered OpenVZ? 
If you have all linux guests, the OpenVZ container approach is far more 
performant. We have converted our whole hosting environment from Xen to 
OpenVZ because of poor disk and network performance with Xen. Haven't 
looked back - its been awesome.

Sorry to not actually fix your problem though :) (I think someone else 
has in this thread)

thanks
