Hi Bala,

Please always post to the mailing-list address (emb...@li...) and not to individuals. It can always help others to have a view in issues of other developers.
Now regarding your particular issue with Pandaboard...

Without a more detailed problem description, it will be hard to help you. You can perhaps send a log of the build output which gives more information on the location and type of error. 
> 1. syntax mismatching with parenthesis( )
Should be rather easy to solve by analyzing where and why this happens. This kind of errors typically come with conditionnal compilation (#if/#ifdef) and it is possible that when compiling for Pandaboard you activate code that was not activated for Desire or other platforms. Have a look at the location of the error in the code. You should find quickly where there is/are problem/s with parenthesis.

> 2. Respective /vmlinz is not present.
If you have compilation issues, the binaries won't be generated... So first fix the build issues then we can tackle down the Linux (dom0/U) images problem.

How did you patch the kernel for Pandaboard ? Did you paravirtualize everything needed for Panda ? 
You can have a look at the adaptations done for HTC Desire HD in this commit for example: http://sourceforge.net/p/embeddedxen/code/ci/cb104712cccd5c7c8c07583746707e3255c28915/ 
This is the inclusion of Desire HD (2.6.32-dom0) into EmbeddedXen.

And the patch: http://sourceforge.net/p/embeddedxen/code/ci/6358dd0031e04f2a6305ac0323af7af9057452e8/tree/tools/patches/linux-2.6.32-dom0.patch
This is the patch which must be applied on top of original 2.6.32 HTC kernel. These resources should give you all necessary information you need to port EmbeddedXen on Panda.
The original Desire HD kernel can be downloaded from http://www.htcdev.com/devcenter/downloads > Filter: 
Device: HTC Desire HD
Android version: v2.2 
Kernel source code > Find files.

The kernel we took as a base is the latest one in the list
Desire HD - N/A - N/A - N/A - 2.6.32 - v2.2 - 86.6 MB --> http://dl4.htc.com/RomCode/Source_and_Binaries/ace_2.6.32_g5ed1769.tar.gz

Please note that we do not already support SMP with EmbeddedXen. It is on our roadmap but still not implemented. For the Panda, you'll have to disable SMP and use only one core for now.

Regards,
   Romain
