This patch adds two capabilities flags to deal with various aspects
of supporting SG_IO commands on virtio-blk-pci devices:
QEMU_CAPS_VIRTIO_BLK_SCSI
set if -device virtio-blk-pci accepts the scsi="on|off" option
When present, this is on by default, but can be set to off to disable
SG_IO functions.
QEMU_CAPS_VIRTIO_BLK_SG_IO
set if SG_IO commands are supported in the virtio-blk-pci driver
(present since qemu 0.11 according to a qemu developer, if I
understood correctly)
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.
