This error does not update the status of the VMs if there is a failure on the VTServer.

Solved. The problem was in file ofelia/vt_manager/src/python/agent/utils/vtRspecInterfece.In commit fdf8a3d398ee14d0f129b778af7da90c943cf25c. There was an update of this file. The original file had some lines commented in parse(), parseString(), and parseLiteral() due to these methods construct the rspec tag in a wrong way and made collide the current empty xml files that we are using to construct de Monitoring/provisioning messages.
