vmx=on with -accel hax

[Rui Prior]

Dear qemu developers,

I found a bug/limitation of qemu on windows (qemu-w64-setup-20200201.exe
from https://qemu.weilnetz.de/w64/ ) that makes qemu terminate
immediately with "VCPU shutdown request" (twice) if I try to use the
"vmx=on" CPU option while simultaneously using "-accel hax".  Without
"vmx=on", it works fine (but it prevents me from using nested
virtualization).

I am using HAXM v7.5.6.

Should you need any further information, please let me know.

Best regards,
