This is not a regression, issue spotted after the kvm-unit-test fork update [1]
The vmx on B-azure-4.15 is not failing with "instruction intercept" test (bug 1931956) anymore, but failing with this "EPT A/D disabled" test instead.
Test log:
Test suite: EPT A/D disabled
EPT - guest level 4 page table is not mapped.
EPT - guest level 4 page table is not mapped.
PASS: EPT basic framework
PASS: EPT misconfigurations
EPT - guest level 4 page table is not mapped.
PASS: EPT violation - page permission

FAIL: EPT violation - paging structure
PASS: MMIO EPT violation - read
PASS: MMIO EPT violation - write
PASS: EPT - MMIO access
PASS: EPT - unsupported INVEPT
I haven't found a way to split this test out of vmx.
