Thank you Andrew. &nbsp; That helps. &nbsp;I like to allocate lots of space because I see here (frequently): &nbsp;&quot;I made a small machine and I am running out of space&quot; &nbsp;So the above helps a great deal.

It's always better to create a small disk, and expand it (supported and easy), because over allocating and creating a large disk, and using up all the storage is more difficult to resolve!

Yes, I agree. I recommended that in another thread I was answering and another expert said it was Overkill. If the space is not used, then I do not think it is overkill. <br />

Thanks again.

there is another issue with hosts datastores (it's not good admin if you allocate all the datastores to virtual machine disks) &nbsp;because space is required for the SWAP file (just like workstation), and Snapshots as well, so host datastores should be left 20-30% free!!

In VMware Workstation, if I make a new machine, I can set disk space to be 100 GB for a (say) Windows 7 machine. It uses 50 GB and the remaining space is NOT allocated (I do not pre-allocate) but within the 100 GB limit, I can use space as I need. I like this approach.<br />
<br />
For VMware ESX or for Hyper-V, if I make a new machine, is my space allotment pre-allocated? or not pre-allocated? &nbsp;Is there an option?<br />

Thank you for your help.

Allocating space in ESX or Hyper-V machines.

This topic area includes legacy versions of Windows prior to Windows 2000: Windows 3/3.1, Windows 95 and Windows 98, plus any other Windows-related versions including Windows Mobile.

VMware, a software company founded in 1998,  was one of the first commercially successful companies to offer x86 virtualization. The storage company EMC purchased VMware in 1994. Dell Technologies acquired EMC in 2016. VMware’s parent company is now Dell Technologies.

VMware has many software products that run on desktops, Microsoft Windows, Linux, and macOS, which allows the virtualizing of the x86 architecture.  Its enterprise software hypervisor for servers, VMware vSphere Hypervisor (ESXi), is a bare-metal hypervisor that runs directly on the server hardware and does not require an additional underlying operating system.
