|
|
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.
