Re: vif not being created for domU - [Solved]

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



After some reading, it appears the problem is that the bridge device gets named differently than expected by the xenguest-install.py script.

The bridge interface created by the network-bridge script was called "xenbr2", as it was bridging device eth2.

Changing my xend-config.sxp to force the name of the bridge device to be "xenbr0" enabled the domU to access the bridge device and get an address via dhcp. The change made was to alter the line that calls the bridge script in xend-config.sxp to be:

(network-script 'network-bridge netdev=eth2 bridge=xenbr0')

Looks like the xenguest-install.py is hardcoded with the bridge device on line 174:

vif = [ 'type=ioemu,bridge=xenbr0,mac=%(mac)s' ]

Hi,

I'm running with fc5, kernel-xen0-2.6.17-1.2174.

Yesterday I had a working Xen installation with a domU also running FC5, same kernel, udev, xen, libvirt, and same hardware.

Following a rebuild of the host and reinstall/update of FC5 to same update levels, I'm now hitting a problem installing a domU, where it appears its not setting up a bridged interface for the domU. I think it might be hotplug related?

I've got the same udev, and its running, and I can see the rules files in /etc/udev/rules.d.

Below is the output of several logs and commands.. as far as I can see, the network-bridge script is good, and its set up my interfaces correctly. One minor complication is that my bridged ethernet card is on device eth2, but I've got the amendment in xend-config.sxp to call "(network-script 'network-bridge netdev=eth2')".

I checked the kernel-xen list in bugzilla but couldn't find anything there on hotplug problems.

Any help in figuring out the root cause would be much appreciated! Having gone from working to not-working in a reinstall of the same setup has me very confused.
