Github user ustcweizhou commented on the pull request: https://github.com/apache/cloudstack/pull/1027#issuecomment-153404172 The virtio console is a bridge between hypervisor and vm instance. I am not sure if customers feel good/friendly with this. I donot know if libvirt-java 0.5.1 supports qemu guest agent. If yes, we can send commands/data directly from java. It is another way for implementation. python script and java have their own benifits.
