Xen users - Dec 2007 - Release 0.5.0 of Xen PV drivers for Windows

This message is to announce the 0.5.0 release of my GPL Xen PV drivers
for Windows. Still considered alpha software - test very carefully
before you even consider running it on a production system. Network
drivers are included but are not currently working.

The source is available at:
http://xenbits.xensource.com/ext/win-pvdrivers.hg
And a pre-compiled binary at (i386 XP & 2K3 only):
http://www.meadowcourt.org/WindowsXenPV-0.5.0.zip

Updates since last time:
. It''s now a scsi miniport driver
. CDROM works
. Works under XP as well as 2K3
. Graceful shutdown service (responds to xm shutdown/reboot)

Known issues:
. xm reboot hangs at the end of the shutdown instead of rebooting
. Network drivers don''t currently work (Andy Grover is working on
these)
. Users of the previous release reported some issues that I couldn''t
reproduce, but they all seemed to be on Intel based system and my only
test environment is AMD... any feedback on this release would be greatly
appreciated.
. 32 bit only at this point.
. When the PV drivers are responsible for the boot disk, crash dumps
don''t work.

Any and all feedback welcome.

James

Just to congratulate you for your job which is, in my opinion, a really
good initiative : it pushes things in a good direction for *free*,
efficient and reliable use of virtualization for HVM windows machines.

Only words as feedback for now but, sure, I''ll help by contributing at
the first opportunity.

Really good work!

Btw how did you solve the problem you had earlier with the scsi miniport stuff? 

Any comments about expected performance at this point? Is it already
optimized or still in the "features first, optimization later"-mode?

Can''t test atm, but will do that later.

Hello James,


Thank you for you work, 
it''r really interesting and really useful.

No about my experiments and problems.


I have tried to install your drivers into Windows XP.
I have downloaded the drivers from [1], 
unzipped it and installed it as describe in 
the INSTALL.txt.

The installation process was exactly as you have described
in the INSTALL.txt file. No any errors.

After that I have modified boot.ini (added new boot variant
with the /gplpv key) and rebooted the system.

I have tried to boot using the second boot option in the boot menu
(/gplpv) and have got blue screen of death
(it appeared just after a second as a I have pressed enter in
the boot menu).

I have tried to boot using the first boot option in the boot menu
(without /gplpv). The system have booted without any problem.
After that I have tried to make hot block-attach to
the domain.

sudo lvcreate -n winpv -L 2G /dev/MAIN
sudo xm block-attach 13 phy:/dev/MAIN/winpv /dev/hdd w

(where 13 is the id of the windows domain)


Just after I issue the command Windows goes into blue screen of
death. There are the message on th screen:

DRIVER_IRQL_NOT_LESS_OR_EQUAL
....
Technical information:
*** STOP: .....

***    xenvbd.sys  - Address FC769C787 base at ....


You can take a look at the shot of the screen with the error here [2].


I have tried to change the domain configuration.
I played with acpi, apic and pae parameters.
Domain didn''t want to boot in any combination except 

apic=1
acpi=1
pae=1

This one was used before I''ve started to change apic/acpi/pae
parameters. At least I''ve reverted back to it.

Also I have tried to disable CDROM in the pv domain.
Without success.



Thank you for your any ideas.
And once again thank you for you work

Hello, once again, 

I have tried to install PV drivers

I have got exactly the error [1].

Hi James, thanks a lot for the great work. One question:

- Are these drivers tied to a specific version of Xen Hypervisor? i.e. shall
we use it with released 3.1.0, or can I use it with any hypervisor version
including 3.2 unstable?

Thanks,

Emre

I''ve only really tested it with 3.1.x (worked), and one accidental
attempt with 3.0.x (didn''t work).

Are you using Intel or AMD? What version of Xen?

Can you use debugview from sysinternals to get the output of the crash
dump? The procedure is basically:

1. Don''t boot with /GPLPV
2. Make sure your system is set to write out a crash dump
3. Start DebugView
4. Do a block-attach to make it crash
5. Let the crash dump do it''s thing
6. Boot the system again without /GPLPV
7. Start DebugView
8. Analyse the crash dump (C:\Windows\Memory.dmp probably)
9. Email the output to me

Thanks

James

Hello,
thank you for the answer.


There was information
about my system (xm info, xm dmesg and the windows 
domain config) at the previous letter
(at the and of the letter).

I use AMD, 
host system is Debian (32bit).
Hypervisor is 3.1.1 and Dom0 kernel is 2.6.18 from 
the Debian repo (PAE).

Thank you,

I''m sorry, I don''t know much about windows, so:

How can I be sure that system 
is set to write out crash dump?
Where should I look at to be sure?
It this boot.ini key or something alike
that make a system write dump?

Sorry. Must have missed it. My setup is the same except that my Dom0 is
64 bit. I can''t think that that would make any difference though.

Right click on ''My Computer'' and select
''Properties''. Go to the
''Advanced'' Tab and click the ''Settings''
button inside the ''Startup and
Recovery'' box. In ''Write Debugging Information'', your
options are ''Small
memory dump (64 KB)'', ''Kernel Memory Dump'', and
''Complete Memory Dump''.
You might be able to get away with ''Kernel Memory Dump'', but I
always
choose ''Complete Memory Dump''.

Good Luck!

James
