It's unclear to me what the delta is, but I do see that the 'vmx'
suite has failed. That is to be expected if you're getting your
kvm-unit-tests from the 'master' branch of the kvm-unit-tests repo.
You will need commit 591b5b54bba1 ("x86: Skip APIC-access address
tests beyond mapped RAM"), which is in the 'next' branch of the
kvm-unit-tests repo, but which has not yet made it to the 'master'
branch.
