[Xen-users] netbsd/amd64 5.1rc4 domU network on XEN4 and current dom0

[Pierre-Philipp Braun <pbraun@xxxxxxxxxxxx>]

Hi,

I'm running a Slackware64 dom0 on top of XEN 4.0.1.  I tryed both xen/next
and xen/master kernel repositories, same problem : the NetBSD guest sees
its network interface (xennet0) but it's unusable.  It doesn't ping nor
responds to ping.  Another guest, RHEL5 (2.6.18) network works fine.  I
tryed both -bridge and -route configurations (I would like to keep the
latter), no changes.

Although the dom0 shows fe:ff:ff:ff:ff:ff for the virtual interfaces, and
show dom0's IP instead of the guests' one, the guest (both rhel and
netbsd)
do have the right MAC addresses and IP (rhel:192.168.0.11,
netbsd:192.168.0.12).

dom0 network (ifconfig) :
