In the previous post, we took a look at creating a virtual machine in Hyper-V and the various settings and considerations for choosing options for our new virtual machine. One of the topics mentioned that we want to take a closer look at here is how to create a fixed size hard disk on a guest Hyper-V VM. There are still a lot of differing opinions and conflicting documentation out there between when and when not to use dynamic disks vs fixed size disks.
