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,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?

    Current state here is right now:

    -l CentOS-Stream-9-20211222.0-x86_64-dvd1.iso

    works, but

    -l CentOS-Stream-9-20211222.0-x86_64-boot.iso

    NOT.

    A quick test with

    -l CentOS-Stream-9-20211222.0-x86_64-boot.iso,kernel=isolinux/vmlinuz,initrd=isolinux/initrd.img

    booted but hangs forever in the middle of the anaconda process.

    I assume that some metadata is missing in the boot.iso file. Like the .treeinfo file (its included in the dvd.iso file).

    Example:
    https://mirror1.hs-esslingen.de/pub/Mirrors/CentOS-stream/9-stream/BaseOS/x86_64/os/.treeinfo
