Title:
vmx_controls test in kvm-unit-test will crash E4v3 azure node with
4.13 / 4.14 kernel
Status in linux package in Ubuntu:

Bug description:
Reproduce rate: 4 out of 4
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_controls test as root:
TESTNAME=vmx_controls TIMEOUT=90s ACCEL= ./x86/run x86/vmx.flat -smp 1 -cpu
host,+vmx -m 2560 -append vmx_controls_test
A side note is that the ubuntu_kvm_smoke_test can pass on this system
(kvm is supported)
Result:
* It seems that the node will crash and reboot itself, output:
timeout -k 1s --foreground 90s /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/vmx.flat -smp
1 -cpu host,+vmx -m 2560 -append vmx_controls_test # -initrd /tmp/tmp.rn9YgIF5XM
enabling apic
paging enabled
cr0 = 80010011
cr3
The cr3 is the last thing that I could see from the terminal.
I don't think this is a regression, check the test report history the
E4v3 node didn't pass this test from the very beginning (marked as
untested, I think it's because the test crashed, so the build task was
marked as failed on jenkins).
We will need to fix our test to make it easier to spot this.
