| 18 | This drivers provides support for virtio based paravirtual device |
| 19 | drivers over PCI. This requires that your VMM has appropriate PCI |
| 20 | virtio backends. Most QEMU based VMMs should support these devices |
| 21 | (like KVM or Xen). |
| 22 | |
| 23 | Currently, the ABI is not considered stable so there is no guarantee |
| 24 | that this version of the driver will work with your VMM. |
