In case you will specify graphics like this: <graphics type='spice' port='-1'/> or <graphics type='spice' port='-1' tlsPort='6000'/> libvirt will automatically add autoport='no'. This leads to an issue that in qemuProcessStop() we don't release that port because we are releasing both port if autoport=yes or only port marked as reserved. If autoport=no but we request to generate port via '-1' we need to mark that port as reserved in order to release it.
