Disk partitioning on Virtual Virtual

Dear Experts,
Creating a disk partition via disk management utility  on virtual machine that runs on hyper visor is same as the the physical machine???? Last time I created the partition of VM that run on hyper v. I found the the new partition created on my physical machine automatically. It was little confusing. Can you throw some light on this issue??

VM is windows server 2016.

Many thanks for your valuable advice in advance

Physycal machine v/s Virtual machine the only difference is the Size of disk space availability
if physycal disk is 1 Tb and making a virtual drive of 10 Gb ... and you want to created a partition of it from VM you have to select remaining available space..

about the Drive it'll map to physycal as it's gets a drive letter on the VM

all the best

Thanks for reply, I have a complete drive lets say drive D: (2.21TB)  on physical machine, I allotted this drive to VM. So now VM  C: drive is approximately 2.2TB and now i want to create the partition on VM. lets say C: (400GB) rest of the storage for other purposes. When I will create partitions on VM will this partitions also reflects on physical machine??

 will I get 2 drives in physical machine instead of one drive D. (2.21TB) ???

May be worth clarifying what we're talking about here:

Windows sees a physical disk, and can partition it as one or more logical disks.
Where Windows is actually a VM, the physical disk is actually a file/drive on the VM host presented as a virtual disk.

So am I right in saying you have:
A physical disk on the VM, host of around 2.21TB.
On this physical disk, you have created a Virtual disk on a VM of 2.2TB which VM Windows sees as a physical disk,
You want to partition this (virtual) physical disk into two partitions, C (400GB) & D (remaining space).

is that correct?
If yes, how you partition the (virtual) physical disk within the VM will have no impact on the 'virtual disk' the Host presents to the VM.
You should still have a single virtual disk file on the host.

DO NOT create partitions in VMs (Windows creates one or two very small ones for it's configuration, but other than that you should NEVER partition a VM.  Add another Virtual Hard disk.  Windows won't care and you'll be able to move the virtual hard disk to other servers if necessary or other partitions on the physical server if you run low on physical disk space.  Partitioning a VM is unwise and should not be done.

Lee is 1000% correct on this. Don't partition drives for VMs. Make the virtual disk (VMDK or VHDX) the size you need. You can make it larger later if needed, but partitioning messes all that up. If you want multiple drive letters, put each on a separate virtual disk.
