I’m running XEN 3.2.0 on a Dell
PowerEdge with 3 NIC cards(1 broadcom and 2 intel e1000). Each NIC card has two
ports on it. To Assign 5 of the 6 NIC ports to domU, I add three lines to
the /etc/modprobe.conf :
options pciback
hide=(0c:00.1)(0c:00.0)(0a:00.1)(0a:00.0)(07:00.0)
install bnx2
/sbin/modprobe pciback ; /sbin/modprobe --first-time --ignore-install bnx2
install e1000
/sbin/modprobe pciback ; /sbin/modprobe --first-time --ignore-install e1000
This seems always work, but, some times
when I restart my server I found some of the domU failed to startup. This
is the erro log in xend.log:
Traceback (most
recent call last):

This is the output of “lspci | grep Ethernet”

It seems the pciback failed to grab the NIC
port(0a:00.1) and e1000 driver has probed the NIC port before pciback. But I cannot
find anything wrong with the modprobe.conf. Does anybody has some
suggestion on this? Thanks in advance!
