CentOS 6 on ESXi 5.1 VMWare Tools not installed message

Hi,

It's not realy a problem but a bit anoying.

The "Message from <myhost>: Install the VMware Tools package inside this virtual machine . After the guest operating system starts, select VM > Install VMware Tools… and follow the instructions."

Waht I did

1) On an ESXi 5.1 I installed 4 virtual machines each VM with the same settings (except for Memory and Virtual disk settings)

2) On all 4 machines I installed CentOS 6 with minimal installation.

3) On all 4 machines I called yum update

4) On all 4 machines I did:

rpm --import http://packages.vmware.com/tools/keys/VMWARE-PACKAGING-GPG-DSA-KEY.pub

rpm --import http://packages.vmware.com/tools/keys/VMWARE-PACKAGING-GPG-RSA-KEY.pub

cat <<EOT > /etc/yum.repos.d/vmw

are-tools.repo
[vmware-tools]
name=VMware Tools
baseurl=http://packages.vmware.com/tools/esx/5.1latest/rhel6/\$basearch
enabled=1
gpgcheck=1
EOT
yum install vmware-tools-esx-nox

I also tried to install the vmware tools that comes with esxi 5.1 directly but with that tools all 4 machines are getting the same Message.

Is this something I did wrong or is this because of some CentOS6 specifica?
