With my hosts at ESXi 5 and my vCenter at version 5, it’s now time to start taking a look at the VMs themselves.
Once the VMs are running on ESXi 5 hosts, you’ll start to see the warning triangle in the task bar of the Windows boxes indicating that the VMware Tools can be updated:
You can either address the update by right clicking on the icon, then going to “Open VMware Tools” and selecting the “Update Tools” box:
Or you could also right click the VM within the vSphere client, go to the “Guest” options, then selecting the “Install/Upgrade VMware Tools”:
You can then select “Interactive Tools Upgrade” or the “Automatic Tools Upgrade”, selecting the “Automatic Tools Upgrade” will reboot the system after it’s done:
The task doesn’t take long, roughly a minute, then the system is rebooted (if you chose the auto option)
Once that’s done, we can now upgrade the Virtual Machine Version to version 8. A couple of the bigger improvements with the new VM Version are the ability to have VMs with up to 32 virtual CPUs, VMs with up to 1TB RAM, suppot of accelerated 3D graphics (including Windows Aero support), support of USB 3.0, and the use of UEFI virtual BIOS.
To do the upgrade, shut the system down. Once the vSphere client reflects that the system is turned off, right click the system and select “Upgrade Virtual Machine Hardware”
Confirm that you would like to upgrade the VM Version
The task completes pretty quickly, and your VM version has been upgraded.
