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
LibVirt : simple API for virtualization Libvirt is a C toolkit to interact with the virtualization capabilities of recent versions of Linux (and other OSes). It is free software available under the GNU Lesser General Public License. Virtualization of the Linux Operating System means the ability to run multiple instances of Operating Systems concurrently on a single hardware system where the basic resources are driven by a Linux instance. The library aim at providing long term stable C API initially for the Xen paravirtualization but should be able to integrate other virtualization mechanisms if needed.

Description
Libvirt provides a portable, long term stable C API for managing the
virtualization technologies provided by many operating systems. It
includes support for QEMU, KVM, Xen, LXC, bhyve, Virtuozzo, VMware
vCenter and ESX, VMware Desktop, Hyper-V, VirtualBox and the POWER
Hypervisor.
