RE: [Xen-users] Very Strange network problem
Hi Chris,
Its very strange. If you manage to fine anything let me know, im sure other
people are having the same issue. I can do some off list troubleshooting, my
only issue is that the box is live in a data center so getting console access
and rebooting is limited but i will test what i can.
Thanks
Ian

I am experienced pretty much the same thing. I though it was possibly
my nic, but more likely the bridging itself. I have a spare machine
that's exhibiting the same symptoms so I will play with it a bit more
today and tomorrow and see if I can dig up anything else useful. I'd
be open to discussing off list if you want to work together
troubleshooting further.
