Re: [Xen-devel] xend with XenAPI in stackless python-2.7

[Eric Camachat <eric.camachat@xxxxxxxxx>]

I just want integrate VMs state into our management interface that written by python.

It did work before, but looks doesn't make sense as you mentioned.

Basically, I want XenAP.py can be used to get VMs information.

Hi,

I am using XEN-4.1.2 and linux-2.6.32 as dom0.

After I upgraded stackless python from 2.5 to 2.7 (and rebuilt xen).

XenAPI became unusable, I spent some time to investigate XenAPI,py, it looks fine.

So, I guess xend has problem with python 2.7, because it always returned method unknown.

Do I have to tweak xend to let it support python 2.7?

Thanks,
Eric

xend and XenAPI are two completely different things.

xend is the old deprecated Xen toolstack, written entirely in python. It has been replaced with the xenlight toolstack upstream.

Xen-API is a separate open source toolstack, written in OCaml. XenAPI.py is just a small python wrapper around the Xen-API XMLRPC interface.

Which toolstack are you expecting to be using?
