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 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. Run the apic test as root:
   
  # TESTNAME=apic TIMEOUT=30 ACCEL= ./x86/run x86/apic.flat -smp 2 -cpu qemu64,+x2apic,+tsc-deadline
  timeout -k 1s --foreground 30 /usr/bin/qemu-system-x86_64 -nodefaults -device pc-testdev -device isa-debug-exit,iobase=0xf4,iosize=0x4 -vnc none -serial stdio -device pci-testdev -machine accel=kvm -kernel x86/apic.flat -smp 2 -cpu qemu64,+x2apic,+tsc-deadline # -initrd /tmp/tmp.onXtr5JVp7
