SCVMM-resize VM?

Anyone use this? I pulled it down from technet and I am using it.

I guess I am wondering how careful I need to be on playing with this so I don't break anything.

Also, one of the largest reasons I am playing with it, I am wondering if I can use it to force a VM resize? One of my VM's grew and doubled in size, and I would like to whack this down. It offers a plethroa of options over the typical hyper-v console.

I also noticed that it can point to ESX hosts? How well does this work?
 
The VM grew? You mean you are using a dynamic disk? From all my testing, i never found a way to convert them to fixed and decrease the size. I spent a lot of time trying to figure that one out. I eventually just re-created the VM with a fixed size disk, which is much better performance anyway. With dynamic, once that space it used it adds more on, and it's usually not contiguous with the original block, so the HDD data is scattered more on the drive.

My favorite tool for working with VHD's is VHDTool. Can create vhd's in a few seconds, then you can store them in the VMM library for later use (I made 10, 20, & 30GB fixed disks for example). It can also expand a fixed disk for more space as well.

Is there a way to rip this VM to another VM with a fixed disk? This is also our exchange server.

How well does migrating VM from one host to another work?
 
If it's a dynamic VHD you can try to "compact" it. Do a search on Technet, the directions are there.

Another option is you can take an image off of the VHD and transfer it to another smaller VHD ..I remember reading about that on Technet as well..google is your friend.

A lot of the Google results where from 200-2008, I was looking for something more modern/efficient.
 
Should be able to do a clone and resize it as part of the process.
 
I've been using SCVMM but sometimes it's showing a delay or does not appear to refresh as fast as working on the console of the Hyper-V server. So I'm now using SCVMM as a monitor but when I need to make changes, go directly to the Hyper-V server. As for compacting the VHD, the method I like to use is edit the disk then covert to fixed.

I haven't tried the VHDTool, or other third party methods, yet. :)

The disk on the disk is like 193 gig or something, and when I go to convert it to a fixed disk I can only make it as small as the physical space it takes. On the disk in th VM, there are 92gigs used, and I'd like to compact it down and make it fixed, my thoughts are if we over-run that we can add a VHD and map a folder to it.
 
Well I just thought of something I never tried. On the VM, use the windows disk manager and reduce the main partition to say 100GB, leave the rest as unallocated. Then try and reduce the size of the VHD. Even though only 93GB is used, the partition is using the whole 193GB.
