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"
autopart
# Clear the Master Boot Record
zerombr
# 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
# cat base-packer.json

"vm_name": "Centos6.5",

}
}
],
"provisioners": [

}
]
}
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.

If you're receiving an error message similar to the following in your EL6 kickstart, you'll need to add
zerombr
to the kickstart command set.You should also have this instead:
From the documentation:
Edit:
I just tried this on a fresh CentOS EL6.5 virtual machine running on a vSphere 5.5 platform... The following worked three times in succession without issue, including a reinstallation on the same disks:
