1. issues when usign Bridged Adapter mode.

cannot get ipv4 address

set to NAT mode first, and get ip address by checking ifconfig

then switch to Bridged Adapter mode, and very importantly, choose the correct NIC (if you are using wifi, choose the wireleass NIC! in my case default is ehterent NIC, and i must change it to my wifi NIC), then check the ip address now using ifconfig. it works for me!

Extension Pack Installation

1. download and install

2. In order for VirtualBox to have access to the USB subsystem, the user running VirtualBox must belong to the vboxuser group. To do this:

% sudo usermod -aG vboxusers <your-username>

Note: if there is no vboxusers group, you need to first add it:

%sudo groupadd vboxusers

Enable USB

1. you need to first add the devices that you want the guest os to access in the hostos virtualbox settings.
