Othewise you won't get any source string for your disk. The line we are talking about is in qemuBuildNetworkDriveURI(). Now, it's virURIFormat that formats the URI and it uses libxml2 for that. In our tests it seems like we should be discarding escape sequences in Format(). Take a look at tests/viruritest.c and you'll see. So maybe a bug in libxml2?
