.\VBoxManage.exe list vms
...
"win1002 debugee" {5f176ebb-a0cc-4dc7-9c6f-988fcbcca867}
...
linux host
mantvydas@~: virtualbox --startvm 'yourVMName or VM UUID' --dbg
Launch the VirtualBox debug console by navigating to "Debug" menu an select "Command Line":
Once you select "Command Line", you will be presented with a console that looks like this:
memory dump will be a raw file dumped to /home/youruser directory
To create a memory dump, issue the below command (also highlighted in the above graphic):

If you want the debug options to be always available, you can:
- export
