We have several backends (https://github.com/os-autoinst/os-autoinst/tree/master/backend). With qemu backend we start QEMU guest *locally* on openQA worker which connects to it via VNC and sends commands. That works fine. + +However, with svirt backend we start QEMU on a KVM or Xen host and then connect to it remotely from openQA worker - the guest and worker are different systems.
