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
