virt-sandbox-service already has a connection to libvirt - no need to
spawn virsh here. Just do something like this (untested):

    self.conn.fetch_domains()
    dom  = self.conn.find_domain_by_name(self.name)
    info = dom.get_info()
    if info.state == LibvirtGObject.DomainState.RUNNING:
         .....error...
