CentOS Stream will install qemu 6.1, which will likely cause VMs failing to boot
(including hosted-engine) if they use Q35 BIOS. Q35 and i440fx worked, but Q35 BIOS is the
default when setting up hosted-engine and the VM failed to start in stage 5 for me.
To get packages to update on CentOS Stream, I ran dnf distro-sync --nobest. This will
update everything but the rsyslog packages, and downgrade the rsyslog packages to the
necessary versions.
You may want to consider sticking with CentOS until Rocky or Alma Linux 8.6 are available.
When RHEL 8.6 is available, advanced-virtualization should be available for Rocky and Alma
Linux once they release their 8.6 versions. This will allow oVirt to be installed on those
distros.
