Operating System Support
Note: All utility software and boot images referenced in this section can be downloaded from the following
Intel web site:

The Intel® Visual Compute Accelerator boots the operating system from the host using a technology known
as Leverage Boot. A “
vcactl
” utility is used to perform all boot operations. The utility loads the operating
system into a RAMDisk which the CPU’s boot from.
Users have the option of downloading one of several different boot images available from the Intel web site
or creating their own boot image. Refer to the
Intel® Visual Compute Accelerator Product Software Users
Guide
for instructions on how to build a boot image.
Alternatively, an option for building a guest OS with pass through graphics is available by using GVT-d
virtualization.
For the host operating system, a
virtIO
driver and a utility are required. The driver and utility are currently
tested with CentOS* 7.1 (kernel update require).
Disclaimer Note:
As these drivers are open source, the option to build them for other Linux based operating
systems is available, however Intel cannot provide support for this option without official validation being
performed by Intel. Driver validation and performance tuning will be the responsibility of those that choose
to build drivers for Linux Operating systems beyond those supported by Intel.
