Xen users - Feb 2010 - Problem with some win3k3 domUs since crash

Yesterday all of my xen servers went down hard and also lost connection
to ocfs2. 95% of the domU''s came back up ok, but I do have problems
with
a few windows domUs. They seem to start ok, but them immediately lose
connection to the network. If I have them on DHCP they are on long
enough to get an address, then they lose connection. If I look at the
properties of the NIC it says 1GB connection. 

I''ve also tried removing the NICs and adding new ones so they get new
MAC addresses. 

I have a generic win2k3 "image" that I use. I copy it, bring up the
domU, rename it, and assign static IP, and I have a new windows domU.
This has always worked in the past but now even that is failing to stay
on the network.  

Any ideas on where the problem could be? This is happening with win2k3
domUs on both sles10SP2/xen_3.2.x and SLES11/xen_3.4.2. 

Thanks,
James

Not sure why, but somehow GPLPV drivers got hosed on these domUs. I
believe I had version 0.9.10 installed. Manually removing them seemed to
fix it. Not sure what performance implications this will have, but at
least the systems are up now.

I used to have some problems with 0.9.x, in that sometime the cloned
domU will be corrupt. The work around at that time was to boot first
disabling GPLPV, and enable it on second boot. Haven''t had a problem
since.

Anyway, since 0.9.x is pretty old, you might have better luck with
0.11.x series.
