Sounds like hvm without pv-drivers, so a lot of i/o-wait would be normal.
Solution => enhance yout kernel / drivers.

Can you elaborate just a bit?
I'm running the stock Debian Lenny xen install (package: xen-linux-system-2.6.26-2-xen-686); domU installed with xen-tools and debootstrap; uname -r for both dom0 and domU returns 2.6.26-2-xen-686

my hardware doesn't support HVM, so everything is PV based

so... I'm not quite sure what I'm missing, how I would deterimine if, in fact, I'm missing pv-drivers, or how I'd install them if they are missing

A few more details would be very much appreciated.

Thanks again,

Miles Fidelman
