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.

Thanks for information! We will wait for master upgrade to update our test binary.

This reminds me, are we still planning on creating "stable" branches for
kvm-unit-tests[*]? This topic of came up in a discussion at KVM Forum as
well, though I can't remember any of the details.
