Public bug reported: 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 apic will timeout 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.
