When hotplugging a chardev, Libvirt opens corresponding file/binds to a socket/does whatever necessary to obtain an FD that is later passed to QEMU. However, if something fails after the FDs were transferred to QEMU and before chardev is actually added via monitor, these FDs are never closed in QEMU. This is rather suboptimal.

Libvirt API for virtualization
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.
For some of these hypervisors, it provides a stateful management daemon which runs on the virtualization host allowing access to the API both by non-privileged local users and remote users.
Layered packages provide bindings of the libvirt C API into other languages including Python, Perl, PHP, Go, Java, OCaml, as well as mappings into object systems such as GObject, CIM and SNMP.
