Re: [Xen-API] XCP Feature propose - send/receive OS information using introspection

[Marco Sinhoreli <msinhore@xxxxxxxxx>]

But I explain about a functionality implemented in Xen (xentore) and
it need only be encapsulated in xenapi. The data to send will be only
string and not to transfer files between domains. To use this function
the user need to have a valid session like others resources used in
api. I don't think it be a security issue.
