I understand the fixed vdisks are really good on performance. However, dinamic disks exist to help users save space and they come with this added benefits of just using the storage that is already used. 

 

I started using a small ssd for cache drive. And my drive is already used because of my VMs. I have 3, where 2 I barely use but they are still there for tests.

 

Does Unraid support dinamic disks because 3 drives using 20gb assigned for a small 128gb ssd is insane.

Yes it does.

Look at the VM FAQ and scroll down for @johnnie.black excellent instruction.

The raw file shows up as 20GB but only the necessary spaces are allocated.

 

If you want to SEE the allocated size = displayed size then change your vdisk format to qcow2.

If you already use raw, you can convert raw to qcow2 using qemu-img from the console.

Don't forget to change the format in your xml to qcow2 as well or it won't boot.

VM FAQ

Where is the VM FAQ in the Forum

It's in Application Support -> VM Engine (KVM) -> VM FAQ

or conveniently link below 😂

 

I might be able to figure something out after reading the FAQ. 

 

If I were to do the commands. I would go through SSH to the server right?

SSH or through the command line (if you haven't passed through the unRAID GPU to a VM).

My VM is to be accessed remotely only. I use remote desktop or VNC if outside my house.
