RE: [Xen-API] squeezed control

[George Shuklin <george.shuklin@xxxxxxxxx>]

Thank you.

I have some questions for this document:

P.8 says: "It sits waiting for incoming requests on its toolstack
interface". Where is  interface is in installed XCP? I thought is was a
socket, but as I understood from source code it use xenstore, the
'squeezed' leaf. But I found no any trace of use 'squeezed' leaf in
working xenstore. Is squeezed clean out records from xenstore after
reading them?

And, if possible, can I see some kind of 'education' code (simple
sample) of interacting with squeezed? 

Thanks.
