[XenAccess-devel] Xenaccess examples with Windows XP/Vista

[Matthew D. <ma...@at...>]

Hi,

I'm trying to get the Xenaccess examples working with Windows.  I ultimately
want to use it with Vista but for a first step I'd be happy to get it
working with XP SP2.  When I try to run the process-list and module-list
examples on Vista or XP, it fails during initialization with "failed to init
XenAccess library: Bad address".  (The full output is below.)

For Vista, I changed the constants in process-list.c to be appropriate
(determined using windbg).
For XP I just used the constants that were already there and verified they
were correct.

I talked with Jim (I've just started on the project) and he showed me a
Windows sysmap(?) file.  I included part of that just so you can tell me if
I got the format right.  I assume it's OK since there isn't an error looking
up PsInitialSystemProcess.

I'm using Xen 3.1.2 and XenAccess 0.4 on Fedora Core 8.

I'm not really sure what to try next.

Thanks for the help.
