Do I need to partition/format the disk on Hyper-V host

Question

Hi there,

I am setting up Hyper-V host first time and will be using Window Server 2019 Standard. Enabling Hyper-V feature on the server to make it host and installing 2 VMs on it.
Do I need to format/partition physical HDD?
If I have 2 partition C (OS drive) and D drive to store VM configs and hard disk. Do I need to leave rest of HDD as unallocated?
How much space I need to store VM configs and virtual hard drive information ?

Thanks in advance

Hello,

Partition into C and D drives. Keep the Hyper-V host Windows installation on C, and store all the Hyper-V data on D. Change the default folder within the Hyper-V settings.

I wouldn't recommend leaving drive space unallocated unless you have some future plans for adding another logical drive. Therefore, I'd recommend giving around 120GB to C and the remaining space to D. When you create your VM's you can use a dynamically expanding disk for your VM's, just be mindful if you are over-committing beyond the available storage on the host.
