It's a hypervisor level virtual machine host and you can use it to install multiple os's on the same machine with little overhead. I've been running haos like that for a few months now and I'm super satisfied.
Any PC that has virtualization features can be used. Unless it's very old, I'd say it's supported. But it may not be enabled in the bios by default. It's called VT-x for Intel and AMD-v for AMD, I think. But both are supported for at least 10 years on almost any PC.
Oh wonderful, it’s an old pc my job was throwing out last summer so it’s like a 5-8yo intel. It’s not powerful by any means, but if I can run enough on it to justify the standby power draw it would be great.
Unfortunately I still have no idea wtf I’m doing lol, but worst case I break it all and wind up buying a home assistant green. I’ve committed to ensuring my home has good air and this is a project I think we’ll appreciate me following through with
