Abstract
A host information handling system (IHS) provides virtualization of host channel adapters (HCAs). A hypervisor partitions a system memory of the host IHS into multiple logical partitions (LPARs). A particular LPAR includes a single instance of an operating system. The single instance of the operating system includes a common layer that provides virtualization of physical HCAs and sharing of the physical HCAs by multiple virtual HCAs.
