Description Stephen Gordon 2014-05-02 19:21:21 UTC

Description of problem:

NFV workloads require that all compute nodes have support for second-level address translation services for large pages (Intel's® Extended Page Tables or AMD's® Rapid Virtualisation Indexing) and hardware support for I/O virtualization (IOMMU/AMD-Vi).

These capabilities are common in most modern hardware but may not always be enabled in the BIOS. This functionality must be confirmed at least during deployment if not periodically.

Comment 1 Stephen Gordon 2014-05-02 19:22:18 UTC

EPT/NPT can be exposed today, depending on on host nova/libvirt configuration, and could theoretically be filtered using the capabilities filter. IOMMU is more problematic.
