[Xen-users] [Xen-devel] HELP! LOSING NETWORK CONNECTION after XEND START (fwd)
Hi,
I am using the latest xen-unstable by Jul. 15th. Everything is dom0 works
fine. But as soon as I input ''xend start'', all the network
connections
just die.
I am using Broadcom NetXtreme network card, with tg3 driver.
I have collected some basic information and post it in the following part.
I remember some one seems to meet the same problem before, and I try to
find the solution is that thread, but no luck.
Could anyone give any help? Thanks.
