Full Procedure
1. Create a VM.
Create (if not already created) and Turn On a ggRock VM with desired Image in local drives mode (This is for compatibility purposes - if the VM were booted in network mode and the network driver were removed during the OS upgrade, the System Image would be rendered un-bootable over the network - not to worry, there are mitigations for this if the issue presents itself, but we need to side-step the issue here while installing OS updates). (See the Virtual Machines Administration Manual for more information). Additionally, please refer to "Controlling a Virtual Machine" for more information on how to control VMs.
NOTE:
If you do not yet have a VM set up on your ggRock server, please follow the steps in "Creating a Virtual Machine" to do so.
2. Enable "Keep Writebacks" in the Settings of the VM.
(See the Machines Administration Manual for more information).
NOTE:
This is a precautionary measure in the event that an update you are installing requires a reboot - without "Keep Writebacks" enabled the changes will be lost on reboot.
3. Turn on the VM.
4. Control the VM.
