I''ve been having issues with domU networking on an IBM xSeries 460. It
is running several guest domains, and most, but not all, of them are
having networking problems. These guest domains HAVE worked properly in
the past, so it is unlikely a setup problem.
HW:
IBM xSeries 460, SAS drives, 8GB of RAM
0000:0f:01.0 Ethernet controller: Broadcom Corporation NetXtreme BCM5704 Gigabit
Ethernet (rev 10)
Distro: SLES 9 SP2
changeset: 8833:39b392a22002 (and 8830 before that)

summary: Fix segment-register dumping in show_registers()
For example, when I ping one of them:
x366-xentest:/skyline/barrera/xm-test # ping x460-xentest-vm8
PING x460-xentest-vm8.ltc.austin.ibm.com (9.3.190.126) 56(84) bytes of data.

vm8 is configured properly:

The networking on the guest domain is set up properly; however, I can''t
ssh or ping any machines.
Out of roughly 10 guest domains, only a couple have functioning networking.
Again, this setup has worked in the past.
