Test VM - ubuntu-20-04_64 - Ubuntu 20.04 64-bit (for IOMMU testing)
===================================================================
Setup:
- Configure a VM tst-ubuntu-20_04-64 with default Ubuntu 64-bit setting,
with a default 10 GB or larger disk.
- Configure the VM with 2 GB of RAM, ICH9 chipset, I/O APIC and IOMMU (AMD or Intel).
- Make sure networking is NAT.
- Disable audio for the VM.
- Install Ubuntu 20.04 amd64.
Disallow "Install Updates During Installation"
- After installation, open "Settings" and configure as follows:
- Power:
- Set "Blank Screen" to "Never"
- Set "Automatic Suspend" to "Off"
- Displays:
- Set screen resolution to 1280x960 (4:3)
- Privacy -> Screen lock:
- Set "Automatic Screen Lock" to "Off"
- Set "Lock Screen On Suspend" to "Off"
- Set "Show notifications on Lock screen" to "Off"
- Disable VirtualBox Guest Additions that ship with Ubuntu by default:
- sudo sh -c "echo 'blacklist vboxguest' >> /etc/modprobe.d/blacklist.conf"
- sudo sh -c "echo 'blacklist vboxvideo' >> /etc/modprobe.d/blacklist.conf"
- Disable auto-mounting of the CDROM:
gsettings set org.gnome.desktop.media-handling automount false
sudo mkdir -p /media/cdrom
Add /dev/sr0 to /etc/fstab for mounting CD (see readme_first.txt for details).
- Enable address translation for Intel IOMMU:
- sudo nano /etc/default/grub
- Change GRUB_CMDLINE_LINUX_DEFAULT="intel_iommu=on"
i.e. remove "quiet splash" and replaces with "intel_iommu=on" instead.
This setting has no effect when AMD IOMMU is configured so always configure this so we can switch testing
AMD or Intel IOMMUs.
- Proceed as shown in readme_first.txt
