https://bugzilla.redhat.com/show_bug.cgi?id=1181408 When we try to hotplug a channel chr device with no target, we will get success (which should fail) in virDomainChrDefParseXML, because we use goto cleanup this place and return an incomplete definition (with no target). In qemuDomainAttachChrDevice, we add it to the domain definition, but fail to remove it from there when chardev-add fails, because virDomainChrRemove matches chardevices according to the target name. The device definition is then freed in qemuDomainAttachDeviceFlags, leaving a stale pointer in the domain definition.

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.
