xen4 on Debian and xmlrpc over ssl

[Alexandre Chapellon <a.chapellon@horoa.net>]

Hello,

I am using xen for quite a while. To ensure better feeling for everybody 
here I use convirt as a VM life cycle manager.

Convirt uses XMLRPC api of xen to talk to the hypervisor, and I 
configured convirt to use it over SSL for peace of mind. It all worked 
nicely with Xen3.2 but I have recently discovered some issues, i assume 
comes from xen4.

My xend-debug.log are full of error messages like this:

Some fonctionnality of convirt that used to work with xen3 do not work. 
As the error message seemed to involve use of SLL with XMLRPC. I 
modified my configuration convirt and xend to use cleartext XMLRPC... 
The error then disappeared and functionnalty that failed works again.

Does anybody has a clue what can cause thoose messages?

regards.
