Enable virtualization on MSI B450 Tomahawk Motherboard

Debian in Boxes

Boxes is an easy way to quickly try out other Linux distributions, for example the current or next release of Debian (Unofficial non-free images including firmware packages). You simply download the ISO-file and spin it up virtually in Boxes, without actually installing it.

To install Boxes:
$ sudo apt install gnome-boxes

You need to enable virtualization in the BIOS, and this is how you enable virtualization on the MSI B450 Tomahawk Motherboard:

  • Reboot and press "Delete" key about once a second to enter BIOS
  • Select "OC" (”Overclocking Settings”)
  • Scroll down to "CPU Features"
  • Change "SVM Mode" to "Enabled"
  • Click ”Settings” > ”Save & Exit” > ”Save Changes & Reboot”

Check if virtualization is enabled and KVM module loaded:

$ gnome-boxes --checks
The CPU is capable of virtualization: yes
The KVM module is loaded: yes
