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:
- leave swap out - I understand this is done already
Correct. There is no swap.
- wipe out the SSH keys, the random seed,
Right after install there are no keys and seed. All these get created when the sshd service is started for the first time
optionally touch /.autorelabel to force a selinux relabel upon next boot (this takes a time and cpu)
AFAIK, right after install all labels should be correct
- install tuned with virtual-guest profile
That can be done, if needed.
- disable tso and gso on the virtual nic
That can be done,too
and wipe out /etc/udev/rules.d/70-persistent-net.rules
Already done
- run ntp & ntpdate
Already done
- enable serial tty for `virsh console` access if needed
That can be done,too
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
