Re: Lwt installation error

[Anil Madhavapeddy <anil@xxxxxxxxxx>]

Try getting this:
https://github.com/xapi-project/xen-api-client

(with the async_test/ example) running against your host.  There's an XML-RPC 
protocol that this talks.  If it works, then deploying the Xen PV kernels 
should be quite easy.
