  • Thread-topic: Windows PV driver live-migration support

Is anyone working on live-migration support for Windows PV domains?  I
am a developer, and I am evaluating the possibility of improving upon
the Windows drivers.

I installed a recent copy of the PV drivers (0.10.0.130) from the
installation packages pointed at in the wiki
(http://wiki.xensource.com/xenwiki/XenWindowsGplPv) and was not able to
get a Windows 2003 domain to properly restore after a migration.  There
were numerous popup boxes on the console about not being able to remove
devices, etc.  I also found some verbiage in
win-pvdrivers.hg/doc/TODO.txt (cloned from the repository) which
indicated that this support wasn't completed (yet).  I am not quite sure
what my expectations should be.

Is there any documentation for this code or a project-plan which I can
consult?  I didn't find anything on the wiki that would help me answer
my questions about what is or isn't supported and what is being actively
worked on (and by whom).

Apologies in advance if I'm asking newbie questions that have already
been asked and answered.  If you can point me to any useful threads on
this subject, please do so.

Thanks in advance.
