[Xen-devel] pcnet32 device eth0 does not seem to be present, delaying initialization
Hi,
I''m trying to bring up an HVM guest with networking support, but I
cannot get the guest to recognize an ethernet interface. The guest is
rhel5, and I''m running Debian linux dom0 on top of xen-unstable-hvm
changeset 8724.
Running `/etc/init.d/networking restart` gives:
Shutting down loopback interface: [ OK ]
Setting network parameters: [ OK ]
Bringing up loopback interface: [ OK ]
Bringing up interface eth0: pcnet32 device eth0 does not seem to be
present, delaying initialization.
[FAILED]
I have tried several stock 2.4 redhat kernels, and I have built a 2.6.12
kernel and taken care to include the pcnet32 driver. The config file
for the guest domain contains the line:
vif = ['''']
`lspci` inside the guest does not show any ethernet interface.
I''m not sure what to do to enable networking.
Thanks,
-Jon

Please try replacing vif = [''''] with vif = [ ''type=ioemu, bridge=xenbr0'' ] Cheers, Aravindh> -----Original Message----- > From: xen-devel-bounces@lists.xensource.com [mailto:xen-devel- > bounces@lists.xensource.com] On Behalf Of Jonathan M.

That did the trick.

Re: [Xen-devel] pcnet32 device eth0 does not seem to be present, delaying initialization
I''m afraid I spoke too soon. vif = [''type=ioemu, bridge=xenbr0''] gives me an eth0 in the guest, but there is no corresponding vifX.0 in dom0. Looking in /etc/xen/xmexample.hvm, I see the comment: # type=ioemu specify the NIC is an ioemu device not netfront I think vifX.0 is the backend, thus there is no reason for it to exist if the guest has no frontend. However, what do I do instead? I have been looking through documentation without luck. Thanks! -Jon Jonathan M. McCune wrote:> That did the trick.
