[one-users] Opennebula and Xen 4.1.0

[Ruben Diez]

Hi:

we are have problems with Opennebula and a Xen 4.1.0....

When we attempt to deploy a machine, the oned.log file says:
[.....]
Mon May  2 13:01:24 2011 [LCM][I]: New VM state is BOOT

The oned version is:

$ oned -v

OpenNebula 2.1.80 is distributed and licensed for use under the terms of the

and the physical node have CentOS 5.6 with Xen 4.1.0

The problem seems to be a error in the libvirt configuration:

virsh # version
Compiled against library: libvir 0.8.2
Using library: libvir 0.8.2
Using API: Xen 3.0.1
Running hypervisor: Xen 4.1.0


As you can see, the libvirt is connected to the Xen 4.1.0 hypervisor, 
but it is using the API of the Xen 3.0.1

Anyone know about how we can change the libvirt API to the  Xen 4.1.0 one??
