The domain parsing code would auto-add a virtio serial controller if it saw any virtio serial channel defined. Unfortunately it always added a controller with index=0, even if the channel address specified an index != 0. It only added one controller, even if multiple controllers were referenced by channels. Finally, it let the ports+vectors parameters initialize to zero instead of -1, which prevented the controllers accepting any ports. * src/conf/domain_conf.c: Initialize ports+vectors when adding virtio serial controllers. Add all neccessary virtio serial controllers, instead of hardcoding controller 0 * qemuxml2argvdata/qemuxml2argv-channel-virtio.args, qemuxml2argvdata/qemuxml2argv-channel-virtio.xml: Expand to test controller auto-add behaviour --- src/conf/domain_conf.c | 19 ++++++++++++++++--- .../qemuxml2argv-channel-virtio.args | 2 +- .../qemuxml2argv-channel-virtio.xml | 4 ++++ 3 files changed, 21 insertions(+), 4 deletions(-) diff --git a/src/conf/domain_conf.c b/src/conf/domain_conf.c index a9b01d5..64b5cf3 100644 --- a/src/conf/domain_conf.c +++ b/src/conf/domain_conf.c @@ -4385,6 +4385,10 @@ static virDomainDefPtr virDomainDefParseXML(virCapsPtr caps, def->channels[def->nchannels++] = chr;
