[Xen-users] N/w in FC8 - Xen 3.2

[jd <jdsw2002@xxxxxxxxx>]

Hi

  I am seeing strange behavior.... may be I am
overlooking something here. Can anyone throw some
light ?
Thanks.

--   brctl shows 2 bridges... by default the vif from
domU get connected to eth0 bridge...
--   eth0 bridge has peth0

    With this configuration the domU n/w DOES NOT
WORK.


[root@f8-dev xen-3.1]# brctl show
bridge name     bridge id               STP enabled   
 interfaces
eth0            8000.001617b9e423       no            
 peth0
                                                      
 vif58.0

virbr0          8000.000000000000       no

==   While there is another bridge that seems to have
no interfaces added... when I explicitly ask to use
virbr0 in domu config,
       brctl shows as follows... and domU networking
WORKS !!. I do not see any connection beween virbr0
and any physical interface!!

[root@f8-dev xen-3.1]# brctl show
bridge name     bridge id               STP enabled   
 interfaces
eth0            8000.001617b9e423       no            
 peth0

virbr0          8000.feffffffffff       no            
 vif61.0


== Here are interface details...
