CentOS - Dec 2021 - issue with virt-install and CS9 boot iso

I wanted quickly spin up a CS9 system with an virt-install command line 
that in the past worked with fedora34 and C8 but I am getting following
error:

ERROR    Error validating install location: Could not find an 
installable distribution at URL '{trimmed 
path}CentOS-Stream-9-20211222.0-x86_64-boot.iso'

Some search engines found some sites that are giving examples
to pass locations of kernel and initrd. Are the iso files
"wrongly" created or are such parameters required now?

Host: CS8

virt-install
  -n c9x86-parttest -r 3072
  --disk path=parttest.img,size=18,format=qcow2
  -l CentOS-Stream-9-20211222.0-x86_64-boot.iso
  --os-variant rhel9.0  --noautoconsole
  -x "inst.ks=https://example/parttest.cfg"

I don't have? CS8 host handy to check... The man page for "virt-install
-l" notes that this should work if virt-install is run as root.? Is it 
run as root?

The man page also suggests that you should be able to mount the ISO to a 
local directory and then use that path as the argument to "-l".? Have 
you tried that to verify that the structure of the ISO filesystem is as 
expected?
