I'm trying to create a VM for HassIO and I keep getting an error.

 

operation failed: unable to find any master var store for loader: /usr/share/qemu/ovmf-x64/OVMF_CODE-pure-efi.fd

 

I followed this guide here.

 

https://community.home-assistant.io/t/hassio-on-unraid/59959

 

The file is there so I don't really know what's happening as this is my first VM. 

 

HVM: Enabled

 

The above is enabled since I've seen that asked before.

 

 

I found this in the libvirt log

When you creating the VM, choose qcow2 format before browse your vdisk.

Where do I choose that? I have the qcow2 for hassIO on the share and i select it under "Primary vDisk Location" are you saying I have to specify somewhere else that i'm using qcow2?

Yes here 

I'm specifying a vdisk manually. I actually fixed it with a reboot. I just hadn't tried rebooting yet because I had some balancing processes running.
