https://bugzilla.redhat.com/show_bug.cgi?id=1220809 When cold-plugging an RNG device but something fails in qemuDomainAssignAddresses, we will double free the RNG device. Once a device is plugged into the domain, we should set the device pointer to NULL to fix this issue. ... 5 0x00007fb7d180ac8a in virFree at util/viralloc.c:582 6 0x00007fb7d1895cdd in virDomainRNGDefFree at conf/domain_conf.c:19786 7 0x00007fb7d1895d99 in virDomainDeviceDefFree at conf/domain_conf.c:2022 8 0x00007fb7b92b8baf in qemuDomainAttachDeviceFlags at qemu/qemu_driver.c:8785 9 0x00007fb7d190c5d7 in virDomainAttachDeviceFlags at libvirt-domain.c:8488 10 0x00007fb7d23af9d2 in remoteDispatchDomainAttachDeviceFlags at remote_dispatch.h:2842 ...

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.
