[one-users] Libvirt ruby binding integration

[Javier Fontan]

Hello Marco,

Your proposal is interesting and we are thinking in doing that for the  
next release. It will probably be a generic libvirt driver  
configurable to use various protocols and hypervisors. Until we do  
this you can modify the driver to do what you want. In this method (http://trac.opennebula.org/browser/one/branches/one-1.2/src/vmm_mad/kvm/one_vmm_kvm.rb#L158 
) is the code that calls virsh to perform actions:

--8<------
     def exec_kvm_command(host, command)
         Open3.popen3(
             "ssh -n #{host} virsh #{command} ;"+
             " echo ExitCode: $? 1>&2")
     end
------>8--

I think you can change it to something similar to:

--8<------
     def exec_kvm_command(host, command)
         Open3.popen3(
             "virsh -c qemu://#{host}/ #{command} ;"+
             " echo ExitCode: $? 1>&2")
     end
------>8--

I have not tried this change but it can not be very different to that.

Bye
