Wrong libvirt version in bullseye installation

["Gary L. Roach" <garyroach719@gmail.com>]

I have been trying to get a cleen copy of qemu/kvm installed but when I 
try to install qemu-system I get:

    libvirt-clients : Depends: libvirt0 (= 7.0.0-3) but 8.0.0-1~bpo11+1 
is to be installed.

 The same for libvirt-daemon and some others. Version 7.0.0.3 is listed 
as the version used in Bullseye. The 8.0.0-1 version is used in the 
testing version. I have gone through my sources.list files and can not 
find the reason libvirt is trying to be loaded from the testing 
depository. Could anyone help? I have tried clearing the /var/cache 
files. That didn't help.
