Hi all,
Trying to upgrade a KVM host, from CentOS - mostly 7 to a clean CentOS 8 to see if I can get a domain running with a PCI card from the host.
The machine's been a lab box for a while and getting it tidied up has been a bit messy, but I think I'm nearly there, but there's one last thing (there's always one last thing 
)
Which is all by way of preamble to the question, how can a package conflict with itself?
I've stopped the KVM domains, checked the module wasn't loaded and re-installed the package without effect.
Any ideas on a path forward would be gratefully received.
