Hmm. I am seeing

selftests: kvm: sync_regs_test
========================================
==== Test Assertion Failure ====
lib/kvm_util.c:54: kvm_fd >= 0
pid=2840 tid=2840 - Permission denied

4 0x0000564cd52058f9: ?? ??:0
open /dev/kvm failed, rc: -1 errno: 13

There are a couple of other tests that fail with EACCES
It would make sense report these tests as Skipped perhaps.
