It's not that big a deal at this stage, just to enter the devices; I
could reinstall on a MBR disk.

It is an amd64 guest. Xennet0 actually works just fine - it seems the
reset happens due to dhcpcd. I disabled it and manually set the ip
address; now I get some better values with iperf3:

 iperf3 -c 192.168.0.241

Not yet up to the speed of xn under FreeBSD, but much better than re
and wm when viridian is on.

So it is getting there.

Thanks,
