You want to convert an existing CentOS reference machine into a vSphere template so you and your
Rainpole architects can create blueprints for cloning CentOS machines in vRealize Automation. To
prevent any conflicts that might arise from deploying multiple virtual machines with identical settings, you
also want to create a general customization specification that you and your architects can use to create
clone blueprints for Linux templates.
Procedure
1 Scenario: Convert Your CentOS Reference Machine into a Template for Rainpole
Using the vSphere Client, you convert your existing CentOS reference machine into a vSphere
template for your vRealize Automation IaaS architects to reference as the base for their clone
blueprints.
2 Scenario: Create a Customization Specification for Cloning Linux Machines in Rainpole
Using the vSphere Client, you create a standard customization specification for your
vRealize Automation IaaS architects to use when they create clone blueprints for Linux machines.
Scenario: Convert Your CentOS Reference Machine into a Template for
Rainpole
Using the vSphere Client, you convert your existing CentOS reference machine into a vSphere template
for your vRealize Automation IaaS architects to reference as the base for their clone blueprints.
Procedure
1 Log in to your reference machine as the root user and prepare the machine for conversion.
a Remove udev persistence rules.
/bin/rm -f /etc/udev/rules.d/70*
b Enable machines cloned from this template to have their own unique identifiers.
/bin/sed -i '/^\(HWADDR\|UUID\)=/d'
/etc/sysconfig/network-scripts/ifcfg-eth0
c Power down the machine.
shutdown -h now
2 Log in to the vSphere Web Client as an administrator.
3 Click the VM Options tab.
4 Right-click your reference machine and select Edit Settings.
5 Enter Rainpole_centos_63_x86 in the VM Name text box.
6 Even though your reference machine has a CentOS guest operating system, select Red Hat
Enterprise Linux 6 (64-bit) from the Guest OS Version drop-down menu.
If you select CentOS, your template and customization specification might not work as expected.
