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?

I thought xend has a limited XenAPI support aswell.. 
obviously only xapi has the complete support.

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.

Yes, a kind of v0.1 XenAPI, which differs even from the first version of
XenAPI support by xapi AFAIK, and cxapi has moved on considerably since
then.

This list deals with the development of the core Xen hypervisor. For
questions about xapi/XenServer/XCP/XenAPI etc you will most likely have
better luck and be on topic with the lists at www.xenserver.org or the
xen-api@lists.xen.org one.
