Nowadays, passing a kickstarter file requires something like:

$ virt-install ... --extra-args "inst.ks=file://kickstart.ks.template" ...

Note the prepended "inst." before "ks".

However, the man page of virt-install says:

$ man 1 virt-install

   -x, --extra-args
       Syntax: -x, --extra-args KERNELARGS

       Additional  kernel  command line arguments to pass to the installer when performing a guest install from --location. One common usage is specifying
       an anaconda kickstart file for automated installs, such as --extra-args "ks=https://myserver/my.ks"

which is without the required "inst" keyword. More recent versions of Anaconda no longer seem to pick this parameter up without the "inst" keyword, which could cause the installation to become stuck without the user noticing immediately. It might be beneficial to update the man page to include the necessary 'inst' keyword in some form.

This is obviously a very minor inconvenience, but I thought I might still create a Jira issue just in case anyway.
