VMware ESXi CentOS 6.4 kickstart installation

Abhinav asked:

I was trying to do a kickstart installation for CentOS 6.4 but it always show me a warning of re-initializing the HDD as it say may contain invalid partition table or a virtual disk.
I have added below is the snapshot of the kickstart file I am trying to use

# System bootloader configuration
bootloader --append="crashkernel=auto rhgb quiet" --location=mbr --driveorder="sda"
# Clear the Master Boot Record
# Partition clearing information
clearpart --all --initlabel --drives=sda
part /boot --fstype ext4 --size=300
part / --fstype="ext4" --grow --size=1 --asprimary

Even I have created partitions to try as workaround but no resort. Any thoughts how to make this warning go away.
I am trying to do this through Packer-tools for ESXI host (which has 5.5 version) running.
Below is the JSON template I am using

Below is the snapshot of the error I am getting.

PS The image I am using is a custom spin from CentOS 6.4. But I don’t think that kickstart config should have an impact on the same.

My answer:

I found a potential problem:

      "iso_url": "",

The CentOS “minimal” disk is customized and may do unexpected things, as it was intended and customized only to install a single set of packages. It should not be used with a kickstart installation; use the netinstall or DVD images instead.
