Making ESXi Templates

• Shoutout Natalie for sharing the OVA template with me in Google Drive since the web server was down. I downloaded it from there to my mgmt VM

• Select Local file and find the OVA file in your downloads then click next

• Rename the VM and select where it will be located

• Select the datastore you are storing the VMs on and make sure you have selected the Thin Provision option

• Put it on 350-internal

Add DHCP to the Network

Deliverables

• Deliverable 1. Provide a screenshot showing the A records for nested 1-3 similar to the one below.

• Deliverable 2. Provide a screenshot that shows your 4 hypervisors (the nested ones are virtual)

• Deliverable 3. Find the Cloning Task in the vCenter Task Console and provide a screenshot of the successful deployment similar to the one below.

• Deliverable 4. Create another VM and Custom specification for Rocky 8.
  Deploy the template with a custom IP address. Provide a screenshot of both the cloning task as seen in Deliverable 3. As well as a screenshot of the VMs powered on IP address that should match the one entered during New VM Creation.
