Hi and thanks for your answer,

I tried it but it was no use, log says:

cat /var/log/one/oned.log

Tue Dec 20 16:12:08 2011 [MAD][E]: MAD did not answer INIT command

on the front-end machine I have /etc/one/im_kvm directory empty while 
/usr/lib/one/mads is populated. On the host machine I have a directory 
/var/tmp/one where the front-end successfully copied some files and 
directories (not empty):

  * auth
  * hooks
  * im - ganglia.d kvm.d run_probes xen.d
  * image
  * scripts_common.rb
  * scripts_common.sh
  * vmm - kvm xen

Furthermore "virsh -c qemu+ssh://host/system list" works as well as 
qemu+tcp so I guess the two machines are able to find and communicate 
with each other.

On the front-end machine if I try "/usr/lib/one/mads/one_im_ssh 
im_kvm_/im_kvm.conf" and then I type "INIT" I see "INIT SUCCESS--". On 
the host machine there is no such file.

I'm at a loss here..
