[libvirt] [PATCH 0/4] Add HAP to domain features

[Jim Fehlig]

Hardware features such as Extended Page Table and Nested Page
Table augment hypervisor software techniques such as shadow
page table.  Adding HAP (hardware assisted paging) to the
virDomainFeature enumeration allows users to select between
hardware and software memory management mechanisms for their
guests.  I've seen reports [1] of users asking for this
capability in the past.

Patch 3 is an attempt to advertise the feature in hvm guest
capabilities for the Xen hypervisor.  I have not found a way
to discover the presence of HAP support through the xen tools.
Instead, the feature is only advertised on Xen >= 3.3, which
sadly won't accommodate distro backports to older Xen versions.

Thanks for your comments,
Jim
