SPICE has been deprecated since RHEL 8.3 and users are encouraged to move to VNC.

However, creating new VMs in with virt-install, as shown in the documentation as of today in RHEL 8.9 still comes up with SPICE configured.

Follow [1] and the result is:

# virt-install --name demo-guest3 --memory 2048 --vcpus 2 --os-variant rhel8.0 --import --disk /var/lib/libvirt/images/image.qcow2
# virsh dumpxml demo-guest3 | grep graphics
    <graphics type='spice' port='5900' autoport='yes' listen='127.0.0.1'>
    </graphics>

Probably not a good idea to change a default in 8.9.z, but could you please evaluate changing the defaults in 8.10 to VNC? The less VMs a customer has with SPICE the better, especially in late RHEL8 lifecycle, as the upgrade to 9 has proven to be problematic due to SPICE removal.

Alternatively we need to change the entire documentation to suggest --graphics vnc.
