Hello,

Recently Justin T Gibbs, Will Andrews and = myself have been working on
improving the Xen support in FreeBSD. The = main goal of this was to bring
full PVHVM support to FreeBSD, right = now FreeBSD is only using PV
interfaces for disk and network = interfaces when running as a HVM guest.
The main benefits of this = changes are that Xen virtual interrupts (event
channels) are now = delivered to the guest using a vector callback
injection, that is a = per-cpu mechanism that allows each vCPU to have
different interrupts = assigned, so for example network and disk
interrupts are delivered to = different vCPUs in order to improve
performance. With this changes = FreeBSD also uses PV timers when running
as an HVM guest, which = should provide better time keeping and reduce the
virtualization = overhead, since emulated timers are no longer used. PV
IPIs can also = be used inside a HVM guest, but this will be = implemented
later.

Right now the code is in a state where it = can be tested by users, so we
would like to encourage FreeBSD and Xen = users to test it and provide
feedback.

The code is available = in the following git repository, under the branch
pvhvm_v5:

http://xenbits.xen.org/gitweb/?p=3Dpeople/royger/freebsd.git;a=3Ds= ummary

Also, I've created a wiki page that explains how to = set up a FreeBSD
PVHVM for testing:
