The usual recommendations would be "try turning off all checksums,
starting from domU, and then dom0". Others have also say "Ubuntu's
version of Xen sucked, use Debian instead or compile Xen from source".
What I can say is that I'm using several RHEL5.3 dum0, with both RH's
bundled Xen and 3.3.1 from Gitco, both can run Windows domU with PV
drivers just fine, having domU <-> dom0 network performance > 1 Gbps,
and domU <-> outside world close to 100Mbps (mainly because I'm stuck
with 100Mbps Cisco switches).
