Po-Hsu Lin (cypressyew) wrote : vmx_controls test in kvm-unit-test will crash E4v3 node with azure kernel

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

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

The cr3 is the last thing that I could see from the terminal.
