libvirt-cim providers don't unload. Increase provProcs to 64 in /etc/sfcb/sfcb.cfg
The libvirt-cim providers will not unload after use and might prevent
the loading of other providers in sfcb.
Please edit /etc/sfcb/sfcb.cfg to increase the provProcs to 64.
To quote upstream:
"the crux lies in the usage of the libcmpiutil DEFAULT_INST_CLEANUP macro
which prevents the provider from being unloaded. sfcb doesn't unload
providers forcibly by design, so it is not bug.
In the long run, it would probably be desirable to allow the unloading
of the libvirt-cim providers. For now, the number of processes would
need to be increased."
