Can you provide what this is looking for?

Does this break any tools included in EL6? I haven't noticed anything - 
but its difficult to test every possible usage case.

No backported patches are applied from RedHat. They don't have anything 
in the EL range that uses 3.x to bring any patches in from. That means 
they are more likely to cause issues than fix them.

All the compatibility stuff is enabled - you shouldn't see any problems 
here. I'm more than happy to debug issues and work towards fixing them 
if you find any issues.

I migrated the same config from my 2.6.32.x tree then altered new 
options to suit. This should mean it will be as close as possible to 
existing 2.6.32.x tree.

The main problem is that the Xen maintainers are no longer updating the 
2.6.32.x branch with Xen patches. This causes issues as ANY security or 
bug fixes will not be ported to the 2.6.32.x tree. Therefore, moving to 
a properly maintained tree is probably the best option.

The 2.6.32.x tree with Xen hasn't been touched since March this year.
