[Xen-devel] brctl issues...

[Brian Wolfe <brianw@xxxxxxxxxxxx>]

Ok, lets see if I can describe this well enough...

when I run brctl addif xen-bro vif1.0 it fails with the following...

vhost1:~# brctl addif xen-br0 vif56.0
can't add vif56.0 to bridge xen-br0: Cannot assign requested address

ifconfig dumps...
vhost1:~# ifconfig

The funny thing is, a little bit ago it was working just fine. Stock
network script wrappered with the following to setup the bridges...

I've rebooted, restored the original scripts, reinstalled the kernel
that was working, reinstalled xen from the same debs...

Any ideas why brctl would suddenly be unable to add the vifs to the
bridges?
