[Xen-users] multiple interface issues

["McFadden, Gordon" <gordon_mcfadden@xxxxxxxxx>]

 

 

Hi All

 

I am struggling to get two interfaces up in a domU.

I have read lots about this, and have gotten quite far along.

 

I have two bridges

 

[root@irir301-serial5-0-518-point-to-point xen]# brctl show

bridge name     bridge id               STP enabled     interfaces

xenbr0          8000.feffffffffff       no              peth0

                                                        vif0.0

xenbr1          8000.feffffffffff       no              peth1

                                                        vif0.1

 

configured on two physical interfaces.

 

My virtual interfaces seem ok:

The virtual interface entry in my confile seems ok to me.

 

vif = [ 'mac=00:16:3e:00:00:13, bridge=xenbr0', 'mac=00:16:3e:00:01:27, bridge=xenbr1' ]

 

But when I boot my user domain, I see no interfaces.  If I shorten the vif entry to indicate only one interface, that one will work.

Ie

vif = [ 'mac=00:16:3e:00:00:13, bridge=xenbr0'] does generate aneth0 in my domU.

 

It seems like the xm create accepts but does not process correctly the vif entry with two interface spec.  But I have seen this used over and over in examples.

 

Am I missing something?

 

We are using Xen 3.0.2 on FC4 for the host if that is relavent.

 

Thanks

 

Gord
