Hello Manuel, Tru,
first of all thanks for the quick replies. See comments inline.
I have attached a revised version of the kickstart. This time itreally does not install the firmware for Wi-Fi and other exotic cards and the partitioning is adjusted as discussed (one /boot, one / which spawns all disk ( remove --grow if this is not intended ) and no swap). I have also modified vda into sda in the %post section, I assume that if sda is used at install time it's also what should get tuned.
If this is targeting KVM specifically then I'd look also at other optimizations: 1. leave swap out - I understand this is done already 2. wipe out the SSH keys, the random seed, optionally touch /.autorelabel to force a selinux relabel upon next boot (this takes a time and cpu) 3. install tuned with virtual-guest profile 4. disable tso and gso on the virtual nic and wipe out /etc/udev/rules.d/70-persistent-net.rules 5. run ntp & ntpdate 6. enable serial tty for `virsh console` access if needed etc
Most of the above I do in the following ks for cloudstack http://li.nux.ro/download/cloudstack/ks/CentOS6_64bit_password_sshkey.ks
