https://bugzilla.redhat.com/show_bug.cgi?id=1027096 If there's the following snippet in the domain XML, the domain will be lost upon the daemon restart (if the domain is started prior restart): <seclabel type='dynamic' relabel='yes'/> The problem is, the 'label', 'imagelabel' and 'baselabel' are parsed whenever the VIR_DOMAIN_XML_INACTIVE is *not* present or the label is static. The latter is not our case, obviously. So, when libvirtd starts up, it finds domain state xml and parse it. During parsing, many XML flags are enabled but VIR_DOMAIN_XML_INACTIVE. Hence, our parser tries to extract 'label', 'imagelabel' and 'baselabel' from the XML which fails for model='none'. Err, this model - even though not specified in XML - can be taken from qemu wide config file: /etc/libvirtd/qemu.conf. However, in order to know we are dealing with model='none' the code in question must be moved forward a bit. Then a new check must be introduced. This is what the first two chunks are doing. But this alone is not sufficient. The domain state XML won't contain the model attribute without slight modification. The model should be inserted into the XML even if equal to 'none' and the state XML is being generated - what if the origin (the @security_driver variable in qemu.conf) changes during libvirtd restarts? At the end, a test to catch this scenario is introduced. Signed-off-by: Michal Privoznik <mprivozn@redhat.com>
