Debian and Virtualbox (updated for Stretch/9.3)
By Dag, on December 30th 2016, updated February 8th 2018.Dealing with guest additions on a fresh VM, and VirtualBox in general.
Installing guest additions:
# apt update; apt upgrade (reboot after this if kernel upgrade) # apt install build-essential linux-headers-$(uname -r) (Insert Guest Additions CD image...) get optical drive device name with 'blkid' if needed. # mount /dev/sr0 /media/cdrom # /media/cdrom/VBoxLinuxAdditions.run ^ May show weird screen at completion, I repeat it twice for a more intuitive result. ^ If you get permission denied, you may have success with using an interpreter: # sh ./VBoxLinuxAdditions.run # shutdown -r now
Adding Virtualbox itself to a Debian 8 installation (old info, check this now):
# nano /etc/apt/sources.list ^ deb http://download.virtualbox.org/virtualbox/debian jessie contrib # wget -q https://www.virtualbox.org/download/oracle_vbox_2016.asc -O- | sudo apt-key add - # wget -q https://www.virtualbox.org/download/oracle_vbox.asc -O- | sudo apt-key add - # apt-get update; apt-get install Virtualbox-5.1 dkms
Adjusting console resolution:
# nano /etc/default/grub ^ add 'nomodeset' to GRUB_CMDLINE_LINUX_DEFAULT add 'GRUB_GFXPAYLOAD_LINUX=1280x1024x16' (as an example) on the bottom of file. NOTE: check for compatible resolutions with 'vbeinfo' in grub at boot, push 'c'. # update-grub; shutdown -r now
Turn off login spam (goes for any installation really...):
# nano /etc/update-motd.d/10-uname ^ comment it awayyyyy. # nano /etc/motd ^ LCTRL+K(kkkkkkkkkkk4thedarkness and put something custom in issue(+.net) instead).
Since Virtualbox is a type 2 hypervisor, hardware support is not needed (VT-x, AMD-V) but supports it.
