Good Afternoon,

I''m having a problem running Xen 3.3 on Ubuntu 8.04 X64, running 32 bit
virtual machines.
Whenever I set vcpus to be greater than 1 on any of the vms, I see
terrible instability- Multiple reboots each hour.

I''ve tried setting every combination of acpi=off  awiotlb=128
pci=noacpi
and noirqbalance

The Kernel on the Dom0 is 2.6.24-16-xen x86_64
The DomU is 2.6.24-19-xen i686

The physical hosts have 6-8GB of RAM, 80% of which I''m passing through
directly to the DomU.
Any thoughts or help would be appreciated.

-Colin
