Hello Florian,

 In /etc/one/oned.conf at the "  KVM Information Driver Manager
Configuration " section:
IM_MAD = [
      name       = "im_kvm",
      executable = "one_im_ssh",
      arguments  = "-r 0 -t 15 kvm" ]

The executable one_im_ssh is located in /usr/lib/one/mads
or $ONE_LOCATION/lib/mads, depends if you installed OpenNebula self
contained on in root (/).
The one_im_ssh script sets $MAD_LOCATION and
executes $MAD_LOCATION/one_im_exec $*. Maybe you can find out what happens
following the logic found in those scripts.

The monitoring part works for me. I have ONE3.0 on Debian Squeeze (6.0.2) as
frontend. The nodes are also Debian 6.0.2 with qemu-kvm 0.12.5 and libvirt
0.8.3-5.

Have a great day,
v
