In order to calculate the memory that is used by the VM / KVM process associated with the VM, I thought I should subtract the available or set memory - unused memory. The actual data available depends on the hypervisor, the guest OS and whether you have the balloon driver running inside the guest. If you provide that information we probably would be able to help you better. For some of the statistics, you have to instruct the driver to collect them in the first place. Try running the dommemstat command with the --period N option once. Then, try running it repeatedly without that option.
