Title:
qemu with whpx acceleration crashes with vmx=on
Status in QEMU:
New
Bug description:
Under Windows 10, qemu crashes when using whpx acceleration and the vmx=on
option. The reported error is
qemu-system-x86_64.exe: WHPX: Unexpected VP exit code 4
Before the error, it reports
Windows Hypervisor Platform accelerator is operational
The command line is the following:
"C:\Program Files\qemu\qemu-system-x86_64.exe" -accel whpx -cpu
qemu64,vmx=on
It crashes with any model of CPU as long as the "vmx=on" option is added.
Without this option it runs fine (but no nested virtualization).
My processor is an Intel i7-10510U, and I am running Windows 10 2004
(build 19041.572).
