virGetConnectNetwork() calls
virGetConnectGeneric(), which calls
virConnecCacheInitialize(), which is actually a call (only once) to
virConnectCacheOnceInit() which calls
virThreadLocalInit() several times, which calls
pthread_key_create()
If pthread_key_create() fails, it (of course) doesn't log an error
(because it's not a part of libvirt), nor does any other function on
the call chain all the way up to virGetConnectNetwork(). But none of
the callers of virGetConnectNetwork() log an error either, so it is
possible that an API could fail due to virGetConnectNetwork() failing,
but would only log "an error was encountered, but the cause is
unknown. Deal with it." (paraphrasing).
(In all likelyhood, virConnectCacheOnceInit() is going to be called at
some earlier time, and almost certainly pthread_key_create() will
never fail (and if it does, the user will have *much* bigger problems
than an obtuse error message from libvirt)).

==============================
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.
Further information about the libvirt project can be found on the
website:
