Amen to that. I've used this extensively in NetBSD all over the world for at least 10-15 years.

I don’t use wifi for this.

The only thing that is different with this machine compared to my other DOM0s is that this one runs 10_BETA (the others are all 9.2) and that this one uses a 1000T-FDX ure(4) USB-dongle because NetBSD doesn’t yet support the 10G and 2.5G NICs that are onboard.
My suspicion is still that this is me doing something wrong (as in something has changed from 9.2 to 10_BETA, just like the “msr_relaxed=1” setting that Brian pointed out was a change from xen 4.11 to 4.15). I just haven’t found out what yet.
I’m sure there must be people using 10_BETA with Xen DOMUs that have external connectivity. After all, Xen is one of the major improvements in NetBSD 10.
