Summary: XEN PAE domU networking is not working
Product: Xen
Version: unstable
Platform: All
OS/Version: Linux
Status: NEW
Severity: critical
Priority: P2
Component: Guest-OS
AssignedTo: xen-bugs@xxxxxxxxxxxxxxxxxxx
ReportedBy: jyoung5@xxxxxxxxxx
I have an dual Opteron with 6 gig Ram running 32-bit Fedora Core 4 with Xen PAE.
When I launch a DomU with networking this is the output from "ifconfig" in dom0:
[root@xen32p32bit ~]# ifconfig
eth0 Link encap:Ethernet HWaddr 00:0D:60:53:1B:43

RX bytes:6962 (6.7 KiB) TX bytes:6962 (6.7 KiB)
None of the briding gets setup so you cannot do networking from within a DomU.
Here is output from "xm dmesg":
