This is a PCI device that implements a transport for virtio.  It allows virtio
devices to be used by QEMU based VMMs like KVM or Xen.

+          This drivers provides support for virtio based paravirtual device
+          drivers over PCI.  This requires that your VMM has appropriate PCI
+          virtio backends.  Most QEMU based VMMs should support these devices
+          (like KVM or Xen).
+
+          Currently, the ABI is not considered stable so there is no guarantee
+          that this version of the driver will work with your VMM.
+
+          If unsure, say M.
