Xen devel - Nov 2007 - (XEN) platform.c:994:d11 Unaligned ioport access: e15c2292, 4

Suddenly my Windows PV drivers aren''t working... I get this in
''xm
dmesg'':

"
(XEN) platform.c:994:d11 Unaligned ioport access: e15c2292, 4
(XEN) platform.c:994:d11 Unaligned ioport access: e15c1dbe, 4
(XEN) platform.c:994:d11 Unaligned ioport access: e15c1ffe, 4
(XEN) platform.c:1010:d11 Single io request in a movs crossing page

(XEN) platform.c:994:d11 Unaligned ioport access: e15c1416, 4
"

I can''t see anything that I''ve changed in the code
I''ve written, but I
have upgraded to Debian kernel 2.6.18-5 on Dom0 from 2.6.18-4.

Any suggestions? A few other strange things are happening too, like the
vnc port incrementing every time I start a new domain...

I''ll roll back the kernel and see what happens... but it just seems
strange!

Thanks

James

Bah! My bad. I still had version a 3.0.4 of the hypervisor in /boot, and
for some reason ''update-grub'' thinks that 3.0.4 is a later
version that
3.1.1 and put it first in menu.lst... Funny thing is, I think I actually
submitted some updates to the Debian ''update-grub'' xen-aware
routines,
so it probably really is my bad :)

Hi James,

I have the same problem with debian''s "update-grub". Also on
my system it
orders my xen/kernel listing wrong. I don''t think it''s your
mistake.

But as you said "2.6.18-5-xen...", this kernel is compiled against a
xen
3.0.3 patch, so it is maybe not what you want if you are using xen 3.1.x.

I patched my own kernel against a more recent xen 3.1.1 patch and this fixed 
some bugs for me. For example 32Bit-PV Guest on a 64Bit Kernel runs now 
like charm.

P.s.: I am very interessted in your PV Drivers, but I am not a windows 
developer at all. If your driver is available as binary for win xp or vista 
(32bit), I would really like to test it.

I tested the drivers from XenSource and Novell in the past (on a opensource 
xen hypervisor/kernel) and it never worked like expected. After installaing 
the novell driver my hvm-windows just stared directly into a bluescreen and 
with the xensource drivers there were actually some drivers installed, but 
the block-device didn''t seem to work and my hvm guest always had 100%
cpu
utilisation after installing the driver (observerd with xm top), so these 
both drivers doesn''t seem to work on an opensource xen installation.
