xennet0 not connected


NetBSD/amd64 5.1rc4 starts fine as XEN3-DOMU inside a XEN/dom0 pv_ops (slackware64, xen-4.0.1, jeremy's xen/next 2.6.32) !

But I'm missing a network link. xennet0 doesn't ping nor responds to pings. Can you help me troubbleshoot the issue ? Is it caused by the dom0 or the domU ? Network runs fine on another domU (linux 2.6.18).

On slackware64 dom0:
  - brctl shows the vifs for each running guest
  - ifconfig also shows the vifs, beside the bridge interface and peth0

On rhel domU:
  - config has vif = [ 'bridge=bridge0' ]
  - everything's fine, eth0 pings

On netbsd domU:
  - config has vif = [ 'bridge=bridge0' ]
  - xennet0 doesn't ping nor responds to pings

# dmesg | grep xennet
xennet0 at xenbus0 id 0: Xen Virtual Network Interface
xennet0: MAC address 00:16:3e:1d:66:64
xennet0: using event channel 6

# ifconfig xennet0
        address: 00:16:3e:1d:66:64
        inet netmask 0xffffff00 broadcast
        inet6 fe80::216:3eff:fe1d:6664%xennet0 prefixlen 64 scopeid 0x1

also the route:
192.168.0/24       link#1             UC          0        0      -  xennet0

everything *looks* fine (apart enabled=0 but I think that's normal anyway).

help ! sorry in advance if I missed something obvious. At least I'm annoncing our domU is still (almost?) working for pv_ops.
