Description
I was doing vt-x hypervisor development on Virtualbox, I have tried: https://github.com/Gbps/gbhv, https://github.com/tandasat/HyperPlatform, both failed. My latest progress is making vmlaunch successful and DriverEntry returns STATUS_SUCCESS, but windbg(on host) shows *busy* and vm keep freezed, virtualbox logs only show: VMMDev: vmmDevHeartbeatFlatlinedTimer: Guest seems to be unresponsive. Last heartbeat received 4 seconds ago
Any advice on how to troubleshoot this?
Dev enviroment:
Host machine: win10 x64 (physical)
CPU: Intel I7 10700
Virtualbox: 7.0.8 (on win10)
VM: Win7 x64 (in virtualbox)
