xen network bridge with eth0:1 aliases, tmpbridge?

[Frank Liu]

HI there,

I am having some troubles with xen network bridge on Fedora 8.
Searching bugzilla gives me
https://bugzilla.redhat.com/show_bug.cgi?id=193322 which seems to be
old.

This is a default fedora 8 installed with default xen installation. I
assume I should see a "xenbr0" interface, but instead, I see
"tmpbridge"

ifconfig -a

xend-debug.log says:
Error: either "local" is duplicate, or "secondary" is a garbage.
Does that mean xen in Fedora 8 still can't deal with eth0:1 alias?

In my case, I only want xen to use eth0 to bridge to the domU, and
eth0:1 is for some other apps on the dom0. I tried to put a
"netdev=eth0" in the xend-config.sxp and that didn't help.

Thanks!
Frank

This is the fix:

It's not in F8, so feel free to open a bug about it if you wish.

Cheers,
