[Xen-users] no eth device in domU although defined in configuration
Hi.
I run Xen (xen-3.0.1-4) on an Dell Poweredge 750. I use Fedora Core 5
with kernel 2.6.16-1.2096_FC5xen0 as domain0, because Debian doesn''t
work on that system. For the domainU I use the kernel
2.6.16-1.2096_FC5xenU from Fedora Core 5.
I have created my first domainU Debian sarge system using the tool
debootstrap from Debian. I configured the domainU as I did on another
working Xen installation. But on the new one I have problems with
networking.
When I create the domainU everything seems to be ok. In domain0 the
network interfaces are created and added to to the bridge etc.
But in the domainU I don''t get any ethX network interface. The only
interface I get ist lo.
I tried to define the needed interface with
vif = [ '''' ]
and something like
vif = [ ''mac=AA:00:00:00:00:C3, bridge=xenbr0'' ]
but nothing works.
When I try to setup the non existing eth0 I get
SIOCSIFADDR: No such device
eth0: ERROR while getting interface flags: No such device
SIOCSIFNETMASK: No such device
SIOCSIFBRDADDR: No such device
eth0: ERROR while getting interface flags: No such device
eth0: ERROR while getting interface flags: No such device
Failed to bring up eth0.
Although I define the vif I get no ethX in domainU.
My problem seems to be the same as described in
"Configuring network interfaces...SIOCSIFADDR: No such device
- domU - Debian - other DomU OK."

Re: [Xen-users] no eth device in domU although defined in configuration
Problem seems to be solved. At first I had to add the line "alias eth0 xennet" to /etc/modprobe.conf to tell Debian to load xennet when using eth0. Then I had to add xennet module to my domainU by copying recursivly /lib/modules/2.6.16-1.2096_FC5xenU from FC5 domain0 to Debian domainU. Last thing was enabling Debian to load the needed module. Debian sarge base config doesn''t include module-init-tools which are needed to load the 2.6.x kernel modules. I had to download the version for sarge and install it manually. After reboot domU Debian loads module xennet when configuring eth0. Serge Dubrouski wrote:> There could be at least 2 reasons for that: > > 1. bridge-utils rpm isn''t installed. > 2.
