Can anyone please tell how to take a screen shot in the Linux Server of Virtual Box?
VirtualBox provides a menu option to take screenshots of the guest, View → Take Screenshot (Host+E). Alternatively, just Host + E (that’s usually Right Ctrl + E).
If it doesn’t work try this,
A workaround would be to switch to windowed mode and take a screenshot of the VM window contents from the host OS.
Thanks a lot @vkvinay7799, your comment helped to clear my doubt.
