Some of our tests (e.g. qemuhotplugtest) call virDomainSaveConfig(). Now the problem is, qemuTestDriverInit() creates a fake qemu driver and fills it with some fake configuration. At least so we hoped. The truth is, it calls regular virQEMUDriverConfigNew() and then fix couple of paths. Literally. Therefore our tests see regular stateDir and configDir for the user that is running the tests. Directories, where live domain XMLs are stored. Let's just hope our test suite hasn't mangled any of them.
