[Xen-users] Xen networking problem - OK on 3.0.2, broken on 3.0.4
I just confirmed that my methods work with Xen 3.0.2, and I'm not exactly
sure why the same methods wouldn't work with Xen 3.0.4, which is the
version I need to be looking at.
By "working", I mean that the "RUNNING" flag appears on the guest domain's
vif when I run ifconfig and that the private networking between the host
and the guests works.
I'll be investigating more into this issue; meanwhile, any input would be
appreciated.
Thx,
Jun

Installation Notes
Broadcom tg3 Linux Driver
Version 3.71b

I downloaded this from the BroadCom website
http://www.broadcom.com/support/ethernet_nic/netxtreme_desktop.php.
I believe the link you previously gave me (bnx2) is for BCM5706/BCM5708/5709,
whereas I have BCM5754 (tg3).
Any clues? I'm still very lost.
Thx,

I remember that the driver I downloaded from broadcom created a bnx2.ko
module that I then copied into the /lib/modules/2.6.18.xx/somewhere folder.
Are you sure the vorrect Broadcom driver (not the kernel driver) is loaded?

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

When you use broadcom network cards, try the Broadcom drivers instead of
the

When you have other network cards, look at this:
http://lists.xensource.com/archives/html/xen-users/2006-05/msg00817.html
or so. You have to make ethtool -K nicX tx off
while nicX is your network adapter or bridge.
Google for that a little more. You can adjust you scripts to do that
automatically on startup.

Hi,
I've been googling around for several days now, but with no luck. I'm
hoping
someone here might be able to help me out...
I've installed and run Xen 3.0.4 (I need this specific version) with no
problem, and the guests run smoothly; the only problem is that I have
never
been able to get the guests to ping the host (Dom0), or vice versa. I
cannot
access the internet from the guests, but it works fine on Dom0.
I have only one NIC on Dom0 (eth0) that connects to the internet. Right
now
I'm
just trying to get the guests and Dom0 to recognize each other, let alone
guests' internet access.
I've tried network-bridge, network-nat, network-route, and even some
custom
scripts such as network-private
(http://lists.xensource.com/archives/html/xen-users/2006-09/msg00925.html)
and
network-virtual (http://en.opensuse.org/Xen3_and_a_Virtual_Network), with
no
success. I've tried all I could, but here's one thing I believe is the
problem.
When I run ifconfig on Dom0, I see this on the guest's vif:
vif2.0 Link encap:Ethernet HWaddr FE:FF:FF:FF:FF:FF
UP BROADCAST NOARP MTU:1500 Metric:1
RX packets:0 errors:0 dropped:0 overruns:0 frame:0
TX packets:0 errors:0 dropped:0 overruns:0 carrier:0
collisions:0 txqueuelen:32
RX bytes:0 (0.0 b) TX bytes:0 (0.0 b)
As you can see, I don't see a "RUNNING" flag on guests' vifs.
Can anyone please help me out? I'm completely lost here.
If it helps, I'm running Ubuntu 7.04, and I'm experimenting with an HVM
guest (Windows XP).
Thx,
Jun
