MiB ? Never ever used MIB

MiB ? Never ever used MIB

Proxmox shows it as MiB, and the prompt on line 489 also asks for MiB.

1024 MiB would be 1 GiB, but 1024 MB would be 0.95 GiB

Likewise for Storage actually. The node and datacentre show GiB, and when you try to resize disk, but when you click on your storage it shows GB.

The default disk size that we set (2), is actually 2.14 GB
