Description
vmm
Hypervisor-related capabilities
The debugger functions are implemented on top of the 'vmm' module.
vmm : this module contains commands related to the debugger and all hypervisor-related capabilities. Currently, vmm is the only module of HyperDbg.

Examples

The following example unloads vmm module.
1
HyperDbg> unload vmm

IOCTL

This function first invokes IOCTL_TERMINATE_VMX to turn off the vmx operation and IOCTL_RETURN_IRP_PENDING_PACKETS_AND_DISALLOW_IOCTL to complete all the IRP Pending sessions so that we can call CloseHandle.
If you're using APIs, the following export in hprdbgctrl can be used.
1
HPRDBGCTRL_API int HyperdbgUnload();
Copied!

Remarks

This command will continue the debuggee for some time (in Debugger Mode). This means that you lose the current context (registers & memory) after executing this command.
If you use the remove argument, then the driver will be marked to be stopped and uninstalled. You cannot re-load that module again until the target machine is restarted.

Requirements

None
