RE: [Xen-users] XEN - Broadcom issue: survey

["Boudreau Luc" <luc.boudreau@xxxxxxxxxxxx>]

Just to keep you informed, I'm downloading the HP firmware update CD to test 
the firmware update on my server. Maybe this will fix my "Broadcom issue". The 
problem is, 650mb at 9k/s takes a while... I'll post to the list once done.

Ivan,

I don't konw how to replicate the test on my machine (I use Xen 3.1
opensource, thus I don't think I can run a windows PV guest on it, and I
don't know if it applies also to Linux VMs), but I wouldn't be surprised if
this issue was related to non-PV guests.

I'm surprised to see that you're running the same firmware version of my
"good" machine and still have the problem: at this point, I really don't
know what else we could try.

The only other thing is that I didn't try with Xen 3.0.4 (the same running
on my XenExpress machine): maybe 3.1 has a flaw with these network card? Or
maybe there's a "hidden fix" in the XenExpress supplied kernel?
