Lab 14

This lab had a number of tasks that involved VM registering and snapshots. I had worked with these features before so it did not take long to get through this lab.

Deleting VMs

When deleting a VM you need to be careful about how you do it.

Deleting from inventory merely removes the VM from the list of VMs in 'VMs and Templates'. It leaves all the VM files intact. To get this machine back on the list you just find it in the datastore, and register the VM using the VMX file.

Deleting from disk removes the VM from the inventory, and it also removes all the VM files from the storage.

Managing Snapshots

When taking snapshots, you can chose to save the VM's memory or not. If you save the memory in the snapshot, the snapshot will take longer to make and it will take up more space, but if you revert to it, the machine will revert to a booted machine. A storage only snapshot will be off when reverted to, so you will have to start it up. In critical applications it may be necessary to save memory also to reduce downtime in the case that reverting to a snapshot is required.

I this lab I created two storage only snapshots and one with memory saved.
