With this post I start a new series with short tips about tools and frameworks. My main motivation is to add a “safety net” to my OneNote notebook full of notes and, who knows, maybe they are useful to others as well.
Oracle VM VirtualBox
Through the command-line you can issue a number of commands that can be useful for advanced users. (For the rest of the post let’s assume you are in a command prompt where VirtualBox is installed.)
You can use command-line to start a VM in headless mode (you will need to enable remote desktop to access it, be warned!):
VBoxHeadless -startvm <vm-name>
You can also save the state of a running VM using the following command:
VBoxManage controlvm <vm-name> savestate
(Use double quotes to surround the VM name if it has spaces.)
