Bug description:
With Joshua's comment in bug 1719524: "Nested KVM can only be tried on
instance sizes with nested Hypervisor support: Ev3 and Dv3.", although
the instance name is E4v3 here but I can start a KVM on it.
Test vmx_ept_access_test_paddr_read_execute_ad_disabled test will fail
on it.
Steps:
1. git clone --depth=1
https://git.kernel.org/pub/scm/virt/kvm/kvm-unit-tests.git
2. cd kvm-unit-tests; ./configure; make
3. Run the vmx_ept_access_test_paddr_read_execute_ad_disabled test as root:
