Xen devel - Jul 2012 - How to test code changes in Xen? shared objects ?

Hello,

I am new to Xen and am just starting to look at the xen source files. I am
a graduate student and am looking to get a basic understanding of various
components and then choose one sub-system ( maybe memory, networking etc)
to work on.

I have a xen-dom0 ( Fedora 16) and dom-U ( CentOS 5) installed and working.
Xen hypervisor, I have compiled from source.

I have a couple of questions on modifying code and testing my changes.

1. How do I test my changes to the source ? I believe everytime I change
the code, the Xen hypervisor needs to be compiled and reinstalled. Do I
need to make any changes to the Dom0 and DomU after I reinstall Xen ?

2. Is there some kind of shared library ( .so files ) that I can write, so
that I can avoid recompiling/reinstalling Xen everytime ?

I could be totally off the mark here and maybe there is a completely
different way to test changes ? Please correct me if that is the case. If
someone can point me to any guides/tutorials for the same, that would help
too.

Thanks,
Ranjith

If you are just changing the hypervisor itself then there is no need to
make any change to dom0/domU, you just need to reboot to pickup the new
hypervisor.

No, Xen is statically linked and has no shared library or module
loading.
