I’m using xhyve as well, but I’m having trouble getting it to boot newer kernels. 4.4 era works, (16.04) but 18.04 and 20.04 have various failures. I note that docker is built on xhyve and doesn’t seem to have this issue. So it’s not fundamental, but the fix hasn’t made it back to thx mostly abandoned xhyve.

Docker is using hyperkit [1], an xhyve fork that's still actively developed.

Ubuntu 18.04 (Linux 4.15) in xhyve works fine for me. I tried to get 20.04 set up a while ago but I gave up because its installer kept flaking out on me, something about the disk if I remember correctly.

Thanks to another commenter I found https://github.com/evansm7/vftool/issues/2#issuecomment-7354... which is exactly what I needed for Ubuntu 20.04: the idea to use cloud images which bypasses the silly installer.

If you just want to run a recent Ubuntu VM, you can use https://multipass.run/ from Canonical. (It uses hyperkit rather than xhyve as the hypervisor.)

I finally wound up with multi pass, but on the Mac it’s limited to ubuntu images, and I occasionally need to spin up arbitrary distros for testing things.
