The visorbus driver is a virtualized bus for the Unisys s-Par firmware.
|
Virtualized devices allow Linux guests on a system to share disks and
|
network cards that do not have SR-IOV support, and to be accessed using
|
the partition desktop application. The visorbus driver is required to
|
discover devices on an s-Par guest, and must be present for any other
|
s-Par guest driver to function correctly.
