Hypervisor support

You can use PCI functions of RoCE Express with Linux® in LPAR or DPM partition mode or as a KVM or z/VM® guest.

Working with PCI functions is similar regardless of how Linux is hosted. For example, you can configure for high availability through bonded interfaces on Linux in all environments.

Notes:

Other than OSA Express, RoCE Express does not support z/VM VSWITCH technology to provide path redundancy.
Because RoCE Express does not provide a promiscuous mode, you cannot use Open vSwitch in a KVM host to provide path redundancy for its guests.
