Xen users - Nov 2009 - 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.

-- Charlie

That particular problem should be fixed in 0.10.0.134. There may be
other bugs that stop it working but that one at least should be fixed.

A nice to have:

When you release a new driver version, it would be very nice to have a (short) 
list of the new features and bugs fixed in this version.

Sincerly,
Klaus

Charlie,

There are reports of recent gplpv drivers supporting live migration on
old xen versions. Some changes in xen 3.4 broke gplpv live
migration/restore functionality. There is a workaround but it has not
been applied.

Keith, James,

Thank you very much for your responses.

James, I have been testing version 0.10.0.134 today with very good results. 
Clearly, whatever was causing my live-migration problems has been fixed.

Keith, thanks for cluing me in on those other discussions.  Sounds to me like
there is some uncertainty about the expected behavior which is unresolved.  I
will stay tuned to that.

Best wishes. -- Charlie

I just put in a very crude version of that workaround... I''ll upload it
if anyone can give it a bit more testing.

James,

Thank you for working on this issue. Restore is still failing for me.
I will mail details and logs in the morning.

I have attached log files. Here are the details of my setup:
 xen 3.4.1
 dom0: official xen 2.6.18
 domU: fresh install of win2003 ent 32bit sp2 with gplpv_2003x32_0.10.0.138.msi

 a2:~# xm create win2-hvm
 Using config file "/etc/xen/win2-hvm".
 Started domain win2 (id=140)
 a2:~# xentop -d1
 a2:~# xm save win2 win2.save
 a2:~# xm restore win2.save
 Error: /usr/lib64/xen/bin/xc_restore 4 142 2 3 1 1 1 failed
 Usage: xm restore <CheckpointFile> [-p]

 Restore a domain from a saved state.
   -p, --paused                   Do not unpause domain after restoring it

 a2:~#

Let me know if you need more information or have something else for me to test.

What about just a save and restore? That''s all I''m able to
test
unfortunately, so if that works for you but live migration doesn''t then
at least I''ll know what problem I''m chasing.

No luck for me either, live migration is broken with 10.0.0.138 on my
config. Migration does complete as far as Xen is concerned but Windows
sits there without even ping for about 2 minutes, eventually ping
returns but still cannot connect on RDP and the console just shows the
desktop wallpaper and nothing else (No Error or BSOD).

My Config:
Dom 0:
Centos 5.2
Xen 3.31

Dom U:
2 NICs
2 Hard Disks
Server 2003 SP2 I386

Does anyone know what might cause this behaviour? No software at all is
installed on Windows, only SP2, updates and the 10.0.0.138 drivers.

Thanks,

Rob

What about just a save and restore? That''s all I''m able to
test
unfortunately, so if that works for you but live migration doesn''t then
at least I''ll know what problem I''m chasing.

Pings are probably working the entire time but your network gear is
slow to learn about the move. I suspect disk access is blocked which
causes your RDP and console symptoms.

I have done several live migrations now with Xen 3.4.2 and GPLPV .138.
Someone was having problems with migration with 3.4.1 and the issues
were resolved under 3.4.2...
