The computer freezes after starting hv

[LYingSiMon]

Hi, I am having a problem when I use vmware, after installing hv, the system is stuck（windbg not working either）。Soon after, vmware automatically rebooted the system, I cannot provide dump files because there is no bsod。

This is my environment：
cpu：i9 13900k
system：win10 1903

I also tested it on 1909, and it jammed the system, but the phenomenon was slightly different, the 1909 phenomenon was the system black screen and kept flashing.

this is hv's log：

行 1016: [hv] Driver loaded.
行 1018: hv!driver_entry+0x32:
行 1022: [hv] Allocated 2 VCPUs (0x16A000 bytes).

行 1050: [hv] Measured VM-exit overhead (MPERF = 0).
行 1051: [hv] Measured VM-exit overhead (CPU_CLK_UNHALTED.REF_TSC = 0).

This is all the information I can provide. I hope you can help me，thank you.

Supplement: I found a physical machine with i5 8400 win10 1909 and hv works fine.

Have you tried this? #13 (comment)

[LYingSiMon]

yes.

hv/hv/vmcs.cpp

Line 51 in 86ca9f5

exit_ctrl.flags = 0;

The latest code, it's 0 here, so I didn't change it

hv/hv/ept.h

Line 10 in 86ca9f5

inline constexpr size_t ept_pd_count = 64;

Here I changed it to 512

But problems still arise

Happened to me when I had other hypervisors running. Turn off your virtual machines and HyperV
