[libvirt] [PATCH 1/8] RNG updates, new xml parser/formatter code for interface type=hostdev-hybrid

Fri Sep 7 16:14:51 UTC 2012
This patch introduces the new interface type='hostdev-hybrid' along with
attribute managed
Includes updates to the domain RNG and new xml parser/formatter code.
Also introduces a ephemeral tag for hybrid hostdevs.
The ephemeral tag for hybrid hostdevs will be useful for live migration
support at a later stage.

guest instead of <interface type='hostdev'/>.
</p>
+ <p>
+ Libvirt later than 0.10.0 also supports "intelligent passthrough"
+ of VF in the hybrid mode. This is done by using the <interface
+ type='hostdev-hybrid'/> functionality. Similar to <interface
+ type='hostdev'/> the device's MAC address is first optionally
+ configured and the device is optionally associated with an 802.1Qbh
+ capable switch using an optionally specified <virtualport>
+ element (see the examples of virtualport given above for
+ type='direct' network devices). The Vf is passed into the guest as
+ a PCI device and at the same time a virtual interface with
+ type='direct' mode='bridge' is created in the guest. This hybrid mode
+ of intelligent passthrough makes Live migration possible.
