Well, all of these are side problems as long as your VMs refuse to
start... Anyway, given that spice knows how to override the CN check
since its very beginnings (using --spice-host-subject option), this is
no big deal, it's just more convenient if you don't have to.

and you already stated that.
The error message is pretty clear though: there is either something
wrong with certificates themselves or qemu can not access them. If you
can see details of all of them using CLI tools, then the certificates
should be ok. You could verify that ultimately by trying to run
minimalistic qemu manually:
$ sudo /usr/bin/kvm -monitor stdio -spice tls-port=5800,x509-dir=/etc/pki/libvirt-spice,disable-ticketing
you should see just a message like this:
QEMU 0.12.1 monitor - type 'help' for more information
(qemu)
If you see the same error again, there is something wrong with
certificates themselves. If not, verify that they are accessible to the
qemu process - note that it may run under different user than root and
in addition, it may be confined by SELinux or AppArmor. I can't speak
for AppArmor but for SELinux, you may need to restore context of the
files (and directories) to make them accessible for qemu.
