That first command produces the following error, some of which look pretty important to the functioning of oVirt. 

[root@phys1 dwhite]# rpm -e --justdb centos-stream-release

Hello,

I followed some instructions I found in https://www.ovirt.org/documentation/upgrade_guide/ and https://www.ovirt.org/download/install_on_rhel.html by doing the following:

883 subscription-manager repos --enable rhel-8-for-x86_64-baseos-rpms

884 subscription-manager repos --enable rhel-8-for-x86_64-appstream-rpms

885 subscription-manager repos --enable codeready-builder-for-rhel-8-x86_64-rpms

886 rpm -i --justdb --nodeps --force "http://mirror.centos.org/centos/8-stream/BaseOS/$(rpm --eval '%_arch')/os/Packages/centos-stream-release-8.6-1.el8.noarch.rpm"

887 cat >/etc/yum.repos.d/CentOS-Stream-Extras.repo <<'EOF'

888 [cs8-extras]

889 name=CentOS Stream $releasever - Extras

890 mirrorlist=http://mirrorlist.centos.org/?release=8-stream&arch=$basearch&repo=extras&infra=$infra

892 gpgcheck=1

893 enabled=1

904 EOF

905 echo "8-stream" > /etc/yum/vars/stream

906 dnf distro-sync --nobest

907 reboot

908 dnf install centos-release-ovirt45

909 dnf install centos-release-ovirt45 --enablerepo=extras

But now, yum update isn't working because its trying to install centos-stream-release 8.6.1 over redhat-release-8.6.

Surely I shouldn't install CentOS stream release over RHEL release, should I?
See below:

[root@phys1 dwhite]# cat /etc/redhat-release

Red Hat Enterprise Linux release 8.5 (Ootpa)

[root@phys1 dwhite]# yum update

Updating Subscription Management repositories.

Error:

Problem: installed package centos-stream-release-8.6-1.el8.noarch obsoletes redhat-release < 9 provided by redhat-release-8.6-0.1.el8.x86_64

- cannot install the best update candidate for package redhat-release-8.5-0.8.el8.x86_64

- problem with installed package centos-stream-release-8.6-1.el8.noarch

(try to add '--skip-broken' to skip uninstallable packages or '--nobest' to use not only best candidate packages)

you can:

rpm -e --justdb centos-stream-release

dnf update redhat-release -y

rpm -i --justdb --nodeps --force "http://mirror.centos.org/centos/8-stream/BaseOS/$(rpm --eval '%_arch')/os/Packages/centos-stream-release-8.6-1.el8.noarch.rpm"

Alma, Rocky and others are providing centos-release in their own release rpm so this step is not needed there.
