@ryonakano @NN708 I don't have the hardware to test and I'm struggling to find any info online. Will something like this work?

FYI this is how /proc/cpuinfo looks like on a VM of UTM Version 4.7.4 (114) on my MacBook Air (M1, 2020). As you can see neither vendor_id nor flags doesn't present here.

I read an article that says using lscpu instead of /proc/cpuinfo shows more info on arm64. This is how it looks like on the same environment. Maybe we can use this instead? I'm not sure if this works on amd64 too though because I don't have amd64 PCs.

Edit: Ah, the hypervisor flags does not seem to present here though.
