KDSnap allows you to connect to your debugged VM, and save or restore its state, using commands from within the debugger itself. KDSnap Currently supports VMware Workstation and Oracle’s VirtualBox.
Usage:
Change the virtualization platform (default is VMware).
kd> !platform<VMware / VBox>
Connecting to the virtual machine is done using the .vmx file full path when using VMware or using the machine's fullname when using VirtualBox.
kd> !virtualMachine <VMX Full Path / VM name>
Taking a snapshot is done simply by the snapshot coammnd.
kd> !snapshot <snapshot_name>
Reverting to presvious snapshot is done in the same way.
kd> !revert <snapshot_name>
