 Hi Tino,

 I have changed the line as you indicated, and it doesn't change 
 anything...

 But, I've tried to replace the line with:
 vms = VirtualMachinePool.new(client, -2)
 and the VM goes in pending state. However the VM isn't resubmitted to 
 the scheduler (Haizea)

 By the way, oned is running as oneadmin.

 Here is the /tmp/remove_me.txt file (this time, it isn't empty ;P):

 OpenNebula host has failed 31
