Project steamed-windows

Steamed Windows

Running Windows XP under SteamOS in a VM, with IOMMU access to a physical video card.

Hardware

• AMD 6 core CPU (AMD FX 6300)
• AMD 970 chipset motherboard (which IOMMU enabled in BIOS)
• SATA drive (500GB+)

Oracle VirtualBox [FAILED] Notes

• Log in as 'desktop', password of 'desktop'
• Execute sudo bash to become root.
• Create a /etc/apt/sources.list.d/virtualbox.list file:

# cat <<EOF >/etc/apt/sources.list.d/virtualbox.list
deb http://download.virtualbox.org/virtualbox/debian precise contrib
deb http://us.archive.ubuntu.com/ubuntu/ precise main
EOF
# apt-get update

• Install VirtualBox 4.3

# apt-get install virtualbox-4.3
# wget http://download.virtualbox.org/virtualbox/4.3.6/Oracle_VM_VirtualBox_Extension_Pack-4.3.6-91406.vbox-extpack
# VBoxManage extpack install Oracle_VM_VirtualBox_Extension_Pack-4.3.6-91406.vbox-extpack

• Run 'virtualbox' as desktop:

# exit
$ virtualbox

• In virtualbox, create a new VM:
  • Name 'steamed-windows'
  • Type 'Microsoft Windows'
  • Version 'Windows XP'
  • Assign the virtual machine some ram (minimum 2G)
  • Create a virtual hard driver
    • Hard drive type of VMDK - allows us to migrate to VMWare or QEMU later.
    • Select 'Dynamically allocated'
    • Minimum 10G - we will be using a shared filesystem for the actual Steam games
  • Adjust the VM settings:
    • System
      • Motherboard
        • Chipset: ICH9
        • Enable I/O APIC
    • Display
      • Set graphics memory to 128M
      • Enable 3D acceleration
      • Enable 2D acceleration
    • Storage
      • Controller
        • Type: ICH6
      • CDROM
        • Point to your Windows XP install CD or ISO
• Start virtualbox, and install Windows XP (do all your updates, blah blah)
  • In Windows:
    • Control Panel -> System -> Remote
      • Check: Allow users to connect remotely to this computer
  • Install the VirtualBox Guest Additions
• Exit virtualbox, and run the following from the command line:

$ lspci | grep NVIDIA | grep VGA
01:00.0 VGA compatible controller: NVIDIA Corporation GK107 [GeForce GT 640] (rev a1)
02:00.0 VGA compatible controller: NVIDIA Corporation G92 [GeForce 9800 GT] (rev a2)

• Select the higher bus number - that should be your secondary display (02:00.0 is this example)
• Verify that the display has MSI support

$ lspci -v -s 02:00.0 | grep MSI | grep Enable+
	Capabilities: [68] MSI: Enable+ Count=1/1 Maskable- 64bit+

• Attach the secondary display to the VirtualBox

$ VBoxManage modifyvm steamed-windows --pciattach 02:00.0@01:05.0
$ sudo sh -c 'echo 0000:02:00.0 >/sys/bus/pci/devices/0000\:02\:00.0/driver/unbind'

STATUS: FAILED
