CentOS - Mar 2017 - dracut-initqueue errors while using virt-install + kickstart file

I am trying to install a CentOS qemu/kvm virtual machine using a
virt-install script[1].
Since Anaconda text user interface does not permit to users to edit
filesystem type and mount points[2], I decided to use a kickstart file
to customize such settings. To create a kickstart file, I used a trick:
I installed a CentOS machine using Anaconda graphical user interface,
and I made all customizations I need, then when the installation has
been completed, I got the kickstart file (generated by Anaconda) in
/root. [3]
Then I added --grow flags to enlarge "/" as much as possible.
After that, I started the virt-install script passing as input an ISO
and the kickstart file, but the installation failed with logs [4].
Where did I make mistakes?

Thank you for your time

I tried to add
--initrd-inject file://tmp/anaconda-ks.cfg
and
[...] file:/ [...]
but the result is the same. Complete script file at

Problem solved, I had to replace
--extra-args 'ks=file://tmp/anaconda-ks.cfg console=ttyS0,115200n8
serial'
with
--extra-args 'ks=file:/anaconda-ks.cfg console=ttyS0,115200n8 serial'
