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
          UP BROADCAST RUNNING SLAVE MULTICAST  MTU:1500  Metric:1
          RX packets:581 errors:0 dropped:0 overruns:0 frame:0
          TX packets:175 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:0
          RX bytes:45654 (44.5 KiB)  TX bytes:20054 (19.5 KiB)

[root@samos ~]# ethtool -i eth0
Cannot get driver information: Operation not supported


[root@samos ~]# ifconfig eth1
eth1      Link encap:Ethernet  HWaddr 00:25:90:14:D9:22
          UP BROADCAST RUNNING SLAVE MULTICAST  MTU:1500  Metric:1
          RX packets:28600 errors:0 dropped:0 overruns:0 frame:0
          TX packets:665 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:1000
          RX bytes:2470142 (2.3 MiB)  TX bytes:80655 (78.7 KiB)
          Interrupt:16 Memory:fbde0000-fbe00000

[root@samos ~]# ethtool -i eth1
driver: e1000e
version: 1.2.10-NAPI
firmware-version: 1.8-0
bus-info: 0000:07:00.0

NOTICE that only the eth1 ifconfig out put has an "Interrupt" line.


~~~~~~~~~~~~~~BOOT  2.6.18-194.26.1.el5

[root@samos ~]# ethtool -i eth1
driver: e1000e
version: 1.2.10-NAPI
firmware-version: 1.8-0
bus-info: 0000:07:00.0

[root@samos ~]# ethtool -i eth0
driver: e1000e
version: 1.2.10-NAPI
firmware-version: 1.8-0
bus-info: 0000:06:00.0


whazzup with that?
