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.
