[Xen-bugs] [Bug 363] New: Network on domU does not work on blades (dom0
http://bugzilla.xensource.com/bugzilla/show_bug.cgi?id=363
Summary: Network on domU does not work on blades (dom0 uses
physical nic eth1)
Product: Xen
Version: unstable
Platform: All
OS/Version: Linux
Status: NEW
Severity: major
Priority: P2
Component: Hypervisor
AssignedTo: xen-bugs@xxxxxxxxxxxxxxxxxxx
ReportedBy: lge@xxxxxxxxxx
CC: hohnbaum@xxxxxxxxxx,pl@xxxxxxxxxx
I have seen this problem on all of my blades which dom0 use physical nic eth1
instead of eth0 since yesterday (changeset: 7481). None of the domU's network
can reach anywhere.
Here are some info from Dom0 after xend starts:

I am not quite sure if this problem is caused by something in the network-bridge
script that I need to modify to make eth1 work which I did not do. I tried
change vifnum from 0 to 1 in the script. But it did not help.
