But before fixing this I wonder what the exact semantics of > domainCreateLinux are. Is it correct that we don't call > virDomainSaveConfiguration? Yes, that is correct. virDomainCreateLinux() starts a virtual machine with no config file. All trace of it will disappear when it shuts down - a so called 'transient' VM. Alternatively you can define the config first with virDomainDefineXML() and then start it based on this definition with virDomainCreate(). This gives you a persistent VM. Now, while a transient VM is running you can explicitly give it a config file by called virDomainDefineXML with the same uuid, thus turning it in to a persistent VM.
