I have a Supermicro X8SSAX mother board with 2 onboard Intel 82574L
Gigabit NICs.
Stock Centos 5.5 install with the e1000e.ko driver updated to the
latest from Intel website (1.2.10-NAPI)
I am attempting to get a bonded interface working, but while mucking
around I noticed the NICs are behaving oddly in the xen kernel, but
work fine in the non-xen kernel.
When I boot dom0 into 2.6.18-194.26.1.el5xen kernel only one of the
NICs has the proper driver installed:
~~~~~~~~~~~~~~BOOT 2.6.18-194.26.1.el5xen
[root@samos ~]# ifconfig eth0
eth0 Link encap:Ethernet HWaddr 00:25:90:14:D9:22

[root@samos ~]# ethtool -i eth0
