I'd report this to FreeBSD, since this looks like a bhyve issue. I tried 256MB
here using a 6.6 vmm(4) guest VM and it worked fine, so I reduced it all
the way down to 40MB about 16MB at a time and it still worked (but it was
obviously pretty slow). Even 32MB might work but I didn't go that low.
dmesg of that vm below.
