log applicable 'virt-install' command

Page: Create VM

Cockpit would be even better if each UI-creation of a VM logged the equivalent virt-install command used. This would serve as education for users, such that they could transition to scripted creation of VMs. There logs are created for "New machine qemu-NUMBER-NAME" but none of the command used. I realize that cockpit does not shell out to virt-install specifically, but the equivalent command with arg would be great.

Same would be true for podman containers :)

Sorry @paul-hammant for the back and forth, I thought something wrong at first. It's cockpit-project/cockpit-machines#1736 now.
