Testing of it varies a bit; e.g. there's quite a bit of kvm-on-kvm nest testing; there's probably less testing on the various KVM under other things nesting.
Just to note then, and to add a touch of assurance, the majority of the Kata CI runs under nested mode afaik. The metrics do not (as we need the stability of bare metal for reproducible numbers in a reasonable timeframe), and a couple of the arch's run bare metal CIs. But, all the x86 CIs run nested VMs in the cloud.
