OpenNebula

We are going to use libvirt to implement this driver, since we kind of like the XML format they propose and it's overall a good abstraction.

• The POLL action is not working:
  

  POLL 0 localhost one-5
  Exception @TypeError' at ../../bin/one_vmm_kvm.rb:163 - can't convert Fixnum into String
  ../../bin/one_vmm_kvm.rb:163:in @+': can't convert Fixnum into String (TypeError)
          from ../../bin/one_vmm_kvm.rb:163:in @parse_virsh_dominfo'
          from ../../bin/one_vmm_kvm.rb:158:in @each_line'
          from ../../bin/one_vmm_kvm.rb:158:in @parse_virsh_dominfo'
          from ../../bin/one_vmm_kvm.rb:77:in @action_poll'

          from /home/ruben/Virtual/KVM/vCluster/shared/lib/ruby/one_mad.rb:96:in @process'

          from ../../bin/one_vmm_kvm.rb:174
  

• POLL Information should return the state as in the Xen driver

Also error information is not pushed to the core. Example error when deploying a VM:
the following stderr string is available in std_action:

stderr = 
"Connecting to uri: qemu:///system\nlibvir: QEMU error : Failed to add tap interface 'tap0' to bridge 'veth0' : Device or resource busy\nerror: Failed to create domain from /home/ruben/Virtual/KVM/vCluster/shared/var/5/deployment.0\nExitCode: 1\n" 

Unknown Error

is shown in oned.log
