Moving from Hyper-V - conversion issues

[amigliora]

Hi

I am planing to move from Hyper-V to VMWare

Before to do it definitely we start using the free VM option vSphere Hypervisor 6

I was trying to move from our microsoft VM's first with converter, but had a lot of issues.

So I google and found a way to convert VM's with a tool Starwind V2V everything works great on the conversion

The single caveat is the Hyper-V VM was created as growable disk but to convert to ESXi I have to use full allocation (127GB in my case)

With that said, I have my three VM's converted as ESXi with 127GB each.

Is there any way I can convert my VM's into growable disks?

Can I change in any way the size of the disks? all three VM are Ubuntu linux servers

Shall I use a different tool to convert the vhd disk and get this done? (growable disk)

Thanks for helping me

Growable disks in vSphere we call it Thin Provisioning disks, and here is a blog post showing how to convert from thick (fixed/no-growable) to thin (dynamic/growable) disk: Convert VMWare ESXi Thick Provisioned Disk to Thin - Networklessons.com

Hi Richardson,

Thank you very much for the info and sorry my ignorance :s

I went thru the post, had some errors but the comments clarify all for me perfectly.

What I have seen is the size of the files after doing ls -lh is still the same, however in the client application I can see an small used disk and the same big size (as I have seen in the console with the ls -lh command) as provisioned.

With that said, if I have two provisioned disks of 127GB and both using around 20GB, how much real space is allocated in the physical disk?

Having a physical disk of 250GB can I place another VM?

Thanks again

We'll fix it with the next update. I mean there would be an ability to convert into growable and compressed VMDKs
