Re: AW: [SPAM] [Xen-users] Xen networking problem

Hi Hinrich,

Thanks for your response.
I am using a BroadCom Corporation NetXtreme BCM5754 Gigabit Ethernet PCI 
Express (rev 02), and I am currently using the BroadCom driver.
I've also tried the ethtool command you gave me, but it didn't work 
either.
Rather, here's what I saw when I did ethtool on vif's:

root@perodua:~# ethtool vif0.0
Settings for vif0.0:
        Link detected: yes
root@perodua:~# ethtool vif2.0
Settings for vif2.0:
        Link detected: no
root@perodua:~#

So it seems that my HVM Windows XP guest is not "plugged in", hence no 
"RUNNING" flag on ifconfig; how should I go about fixing this?
I'm even more confused now because the following post 
(http://lists.xensource.com/archives/html/xen-devel/2005-12/msg00017.html) 
suggests that a tg3 based machine (tg3 is the name of the BroadCom driver) 
works out of the box with no hassle.
Any ideas? Any help is appreciated.

Thx,
Jun
