Using xen host on freebsd, is com1 the only way to attach to dom0?

[Steven Friedrich]

I can boot a xen kernel, but it appears it doesn't acquire a DHCP address
from my router. Someone suggested using vga=current,keep on xen_cmdline,
but I'm unsure of the valid xen_cmdline arguments.
Do I have to configure and build a FreeBSD kernel or just use what the xen
meta-port builds?
Not having an IP address prevents use of VNC viewer...

Does this mean that the box doesn't boot correctly, or just that the
network card is not working when running under Xen?

The best option would be to hook a serial cable and get the output
from the serial console.

The list of valid xen_cmdline can be found here for the 4.11 ports:

Or here if you are using the 4.7 port:

You don't have to build a specific kernel to run FreeBSD as Dom0, just
using the GENERIC one from either 11.X or HEAD should work.
