xm list -l output is:

    (devices
        (vif
            (idx 0)
            (vif 0)
            (mac aa:00:00:00:00:11)
            (bridge xen-br0)
            (evtchn 14 4)
            (index 0)
        )
        (vif
            (idx 1)
            (vif 1)
            (mac bb:00:00:00:00:22)
            (bridge xen-br1)
            (evtchn 15 5)
            (index 1)
        )

Seems to bee OK.

xend.log has two lines associated by nic:

[2004-11-29 15:47:43 xend] DEBUG (XendDomainInfo:1059) Creating vif 
dom=2 vif=0 mac=aa:00:00:00:00:11
[2004-11-29 15:47:43 xend] DEBUG (XendDomainInfo:1059) Creating vif 
dom=2 vif=1 mac=bb:00:00:00:00:22

no error messages on it.

sorry, I paste wrong the line o:)

domain1: brctl addif xen-br1 vif4.1
can't add vif4.1 to bridge xen-br1: Cannot assign requested address
