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.

53 Allow virtio-mmio devices instantiation via the kernel command line
54 or module parameters. Be aware that using incorrect parameters (base
55 address in particular) can crash your system - you have been warned.
