Re: Bhyve process consumes way too much CPU

Hi,

Is there any specific reason you want it to be installed under Ubuntu?
I’m asking this because I use HasOS(home assistant OS) which is based on
Linux (can’t recall the distribution) and I’m running this for three years
now. No issues at all. I do have even passed through ZigBee usb stick and
it works just fine.
