| ======= |
| |
| You can configure `vfio-user` devices in a `libvirt` domain configuration: |
| |
| 1. Add `xmlns:qemu='http://libvirt.org/schemas/domain/qemu/1.0'` to the `domain` |
| element. |
| |
| 2. Enable sharing of the guest's RAM: |
| |
| ```xml |
| <memoryBacking> |
| <source type='file'/> |
| <access mode='shared'/> |
| </memoryBacking> |
| ``` |
| |
| 3. Pass the vfio-user device: |
| |
| ```xml |
| <qemu:commandline> |
| <qemu:arg value='-device'/> |
| <qemu:arg value='{"driver":"vfio-user-pci","socket":{"path": "/tmp/vfio-user.sock", "type": "unix"}'/> |
| </qemu:commandline> |
| ``` |
