Technical white paper | Implementing SR-IOV for Red Hat Enterprise Linux on HP ProLiant Servers Abstract Single Root I/O Virtualization is defined by the PCI SIG to address the growing need for I/O devices. In many instances, virtual machines share I/O devices. However, the increasing number of virtual machines supported on platforms demands new ways of improving performance and utilization of limited I/O resources.

Technical white paper | Implementing SR-IOV for Red Hat Enterprise Linux on HP ProLiant Servers The following section provides a list of supported Host and Guest operating systems. SR-IOV compliant HP ProLiant servers The following tables list the HP ProLiant servers and minimum System ROM version that are required to implement and enable the Linux SR-IOV feature on each specific platform. Important SR-IOV requires both hardware and system ROM compliance to work.

Technical white paper | Implementing SR-IOV for Red Hat Enterprise Linux on HP ProLiant Servers A crash in the kernel package has been detected Scope: Any HP ProLiant Gen8 system with SR-IOV enabled and running Red Hat Enterprise Linux 6.x X86-64. Resolution: This problem is fixed in Red Hat Enterprise Linux 6.4 Workaround: A workaround is available by limiting the maximum number of virtual functions to less than or equal to 45.

Note SR-IOV requires both hardware and system ROM compliance to work. Your server must have the minimum system ROM version listed in the following tables to enable SR-IOV. If necessary, update the system ROM before beginning enabling SRIOV. Resource description Web address HP and Red Hat partnership website hp.
