| ====== VGA Passthrough ====== | ====== VGA Passthrough ====== | ||
| + | ===== Requirements ===== | ||
| + | ==== For intel: ==== | ||
| + | * CPU that supports Vt-d and Vt-x | ||
| + | * Motherboard that supports Vt-d | ||
| + | * Vt-d and Vt-x must be enabled in BIOS or UEFI | ||
| + | ==== For AMD ==== | ||
| + | * CPU that supports IOMMU and VMX | ||
| + | * Motherboard that supports IOMMU | ||
| + | * IOMMU and VMX must be enabled in BIOS or UEFI | ||
| + | ==== Video Card ==== | ||
| + | * Most Radeon HD cards support vga passthrough | ||
| + | * Only the Quatro Nvidia cards support vga passthrough | ||
| + | * Some Intel graphics work with vga passthrough | ||
| + | |||
| + | ==== Software Requirements ==== | ||
| + | * XEN and KVM both support VGA passthrough, but XEN apparently offers much better performance | ||
| + | |||
| + | ===== Examples ===== | ||
| + | Example XEN passthrough config | ||
| + | <file> | ||
| + | # nut sure if really needed | ||
| + | kernel="/usr/lib/xen-default/boot/hvmloader" | ||
| + | |||
| + | builder = "hvm" | ||
| + | name = "win7x64-hvm" | ||
| + | |||
| + | # RAM size in MB | ||
| + | memory = "4096" | ||
| + | |||
| + | # number CPU cores | ||
| + | vcpus = 2 | ||
| + | |||
| + | vif = ['type=ioemu'] | ||
| + | |||
| + | # boot from cd and hdd | ||
| + | disk = ['phy:/dev/virtual-machines/win7x64,hda,w','file:/home/user/images/WIN_7_PROFESSIONAL.iso,hdc:cdrom,r'] | ||
| + | boot="dc" | ||
| + | |||
| + | # boot from hdd | ||
| + | #disk = ['phy:/dev/virtual-machines/win7x64,hda,w'] | ||
| + | #boot="c" | ||
| + | |||
| + | # enable remote vnc access until video card driver is installed | ||
| + | vnc = 1 | ||
| + | |||
| + | acpi=1 | ||
| + | sdl=0 | ||
| + | serial='pty' | ||
| + | |||
| + | # list your pci devices (HD7950,HD7950,USB) | ||
| + | pci=['01:00.0','01:00.1','00:1a.0'] | ||
| + | </file> | ||
| + | |||
| + | ===== Sound and USB ===== | ||
| + | * Since the physical video output of the passed video card is used there will be no SDL/VNC screen this means that a sound card must also be passed for the vm to have sound | ||
| + | * For that same reason as above you will want to pass one USB controller for input | ||
