  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.
