I'm not 100% sure which change fixed my problems with using SPICE on
Fedora 36, but one or a combo of them fixed it. Even better is that
everything else is working, too. I can:

- use the SPICE display without being prompted in virt-manager to
  enter a password
- tcp and tls connections to the host are both working wtih
  virt-manager, virt-viewer and virsh
- GSSAPI is working with virtproxyd
- polkit is used for local connections and qemu+ssh URI in
  virt-manager, virt-viewer and virsh, but only if I add my IPA user
  to the local "libvirt" group
- managing the KVM from cockpit is working again
- Remote Viewer link from cockpit _finally_ works (it never has before)

I ended up removing most of my changes to the virtqemud.conf and
virtproxyd.conf files and went with the defaults. Where I did make
changes was to change from polkit to SASL based authentication in
virtproxyd.conf and the removal of client side verification: I don't
need the client side verify to be enabled since I'm using GSSAPI. I
also added a couple of IPA users to the allowed users list in both
files.

I've rebooted the host a few times, restarted the KVM, and cleared my
kerberos cache to see if it would break, but all of it stayed working.
I think the move to the modular libvirt and my first time setup of TLS
usage with libvirt has been a success.

I wish I knew why the SPICE display wasn't working yesterday. I also
don't know why TLS and TCP connections where giving me GSSAPI errors
yesterday and today, stopped. I successfully connected with both after
I added my IPA user to the local libvirt group. But, I also tried again
without being in the libivrt group and that also worked. That's
annoying since it's not clear what was wrong.

I guess I can't point fingers at IBM since SPICE _is_ still working in
F36. I'm hoping it stays that way. Also, dropping it in RHEL just
doesn't make a whole lot of sense. I'm still concerned about RH not
working on the development of SPICE in the future and I don't know how
many people outside of RH are involved with the project.

Anyway, at least for the meantime the F36 desktop running the KVM is
working smoothly. I don't know what I'll do with my home "production"
kvm host since it's on AlmaLinux 8. When I migrate it to AlmaLinux 9
(and move to modular libvirt), I'm going to lose the SPICE support. :/

Thanks for the help! :)
