It also seems likely that the perf hit from x86_64 -> ARM64 emulation, even if the emulation is really excellent, might very well eat up any battery savings from the more efficient ARM chip.
My understanding is that ARM chips work fine for gaming when games are built for ARM, but that is far from the norm at the moment.
Oh that’s cool! I thought virtio and such were KVM-specific things. I have never been super clear on the relationship between QEMU and the hypervisor itself, like where one ends and the other begins.
