On NetBSD-5.0, adding a static ARP entry with arp -s will fail with a
kernel message:
# arp -s 00:16:3e:52:c1:ec
arp_rtrequest: bad gateway value

Despite the error message, a static entry is created in the routing table:
# netstat -nr|grep 15       00:16:3e:52:c1:ec  UHS        0        1      -  xennet

However, nothing appears in the ARP table:
# arp -a|grep 15 || echo nothing!

And any attempt to exchange data with the host fails with the kernel
arplookup: unable to enter address for 
    on null (could not allocate llinfo)
arpresolve: can't allocate llinfo on xennet0 for

On a NetBSD 5.0 domU:
arp -d $ip
arp -s $ip $mac
ping $ip

Unknown yet. That problem did not exist with the same setup (dom0, Xen
version) when the domU was running NetBSD-4.0
