# Install guide for QEMU and VFIO
|
||||
## ArchLinux
|
||||
### Install the necessary packages
|
||||
```
|
||||
# pacman -S qemu ovmf
|
||||
```
|
||||
|
||||
### Enabling IOMMU support on boot
|
||||
#### For `systemd-boot` edit `/boot/loader/entries/arch.conf` and add `intel_iommu=on` **OR** `amd_iommu=on` and `iommu=pt`.
|
||||
```
|
||||
# AMD
|
||||
options root=/dev/sda2 amd_iommu=on iommu=pt
|
||||
---------------------------------------------
|
||||
# Intel
|
||||
options root=/dev/sda2 intel_iommu=on iommu=pt
|
||||
```
|
||||
Reboot.
|
||||
|
||||
#### For `GRUB` edit `/etc/default/grub` and append your kernel options, `intel_iommu=on` **OR** `amd_iommu=on` and `iommu=pt`, to the `GRUB_CMDLINE_LINUX_DEFAULT`.
|
||||
```
|
||||
# AMD
|
||||
GRUB_CMDLINE_LINUX_DEFAULT="amd_iommu=on iommu=pt"
|
||||
---------------------------------------------------
|
||||
# Intel
|
||||
GRUB_CMDLINE_LINUX_DEFAULT="intel_iommu=on iommu=pt"
|
||||
```
|
||||
And then automatically re-generate the grub.cfg file with:
|
||||
```
|
||||
# grub-mkconfig -o /boot/grub/grub.cfg
|
||||
```
|
||||
Reboot.
|
||||
|
||||
After reboot IOMMU should be working:
|
||||
```
|
||||
$ dmesg | grep -e DMAR -e IOMMU
|
||||
--------------------------------------------
|
||||
[ 0.492684] AMD-Vi: IOMMU performance counters supported
|
||||
[ 0.494370] AMD-Vi: Found IOMMU at 0000:00:00.2 cap 0x40
|
||||
[ 0.494644] perf/amd_iommu: Detected AMD IOMMU #0 (2 banks, 4 counters/bank).
|
||||
```
|
||||
|
||||
That's everything; unlike two GPU passthrough you don't need to load kernel modules on boot.

# Troubleshooting

|

## QEMU can not allocate memory
|
||||
|
||||
```
|
||||
qemu-system-x86_64: VFIO_MAP_DMA: -12
|
||||
qemu-system-x86_64: vfio_dma_map(0x7fae44695a00, 0xc0000000, 0x40000, 0x7fab29e00000) = -12 (Cannot allocate memory)
|
||||
qemu: hardware error: vfio: DMA mapping failed, unable to continue
|
||||
```
|
||||
|
||||
Solution:
|
||||
```
|
||||
ulimit -l $(( $(echo $RAM | tr -d 'G')*1048576+10 ))
|
||||
```
|
||||
|
||||
Note: This is already addressed in the `windows.sh` script.
