The Virtualbox post

Mainly to myself, my repository of tips and tricks of running Virtualbox under Linux. Feel free to use at your own risk.

Configuration location

/home/$USER/.config/VirtualBox

Connected USB devices not showing up in the usb filter
Check, and add your user to vboxusers group

sudo usermod -a -G vboxusers $USER

Running Guest OS with different date time than Host OS
This is really useful to run old software with time limitations without messing up with the Host OS date/time settings.

It’s easy to specify a time offset from the Host OS in microseconds. 

First get the vm name

VBoxManage list vms

Secondly apply the desired offset (example -1 year clock).

VBoxManage modifyvm "name in vm list" --biossystemtimeoffset -31536000000

(1y = 365d * 24h * 60m * 60s * 1000m)
