And I just learned that this is Citrix-Xen specific, which would be a 
reason that it is not in any distribution, i.e. no such bindings are 
part of the code.

This would imply that there is a potential that CloudStack depends on 
APIs that are only available in the Citrix incarnation of Xen. This in 
turn would put CS into an unfortunate position as CloudStack will not be 
able to run on any distribution that supports Xen ( origin), but 
will only be able to run on distros that also get Citrix-Xen.

This newly gained insight of course makes some of the earlier comments i 
made in this thread useless. What would have to happen is that the 
generation code would have to be pushed to and CloudStack would 
have to limit itself to those APIs.

Based on the above I think there is a lot of clarification necessary 
w.r.t. the dependency list and it is necessary to sort out what the 
Citrix product will use (Citrix-Xen presumably) and what an open source 
incarnation of CloudStack depends on.
