For SCSI and SATA devices controller and unit are used to specify drive address. For IDE devices - bus specifies IDE bus, becase usually there are 2 IDE buses on IDE controller. Parallels SDK allows to set drive position by calling PrlVmDev_SetStackIndex. Since PCS VMs have only one controller of each type, for SATA and SCSI devices it simple means position on bus, for IDE devices - 2 * bus_number + position_on_bus. This patch fixes mapping from libvirt's disk->info.addr.drive to parallels's 'StackIndex'. Signed-off-by: Dmitry Guryanov <dguryanov@parallels.com>
LibVirt : simple API for virtualization
Libvirt is a C toolkit to interact with the virtualization capabilities
of recent versions of Linux (and other OSes). It is free software
available under the GNU Lesser General Public License. Virtualization of
the Linux Operating System means the ability to run multiple instances of
Operating Systems concurrently on a single hardware system where the basic
resources are driven by a Linux instance. The library aim at providing
long term stable C API initially for the Xen paravirtualization but
should be able to integrate other virtualization mechanisms if needed.
