Does Virtual Server 2005 R2 have a command line interface, that's versatile enough?

Here is a situation. I run a Win2k VM on an old memory constrained machine. I allocate it 378MB of RAM and the VM runs just fine. Once a month, inside the VM, I backup the (a very large) database, compress it using 7Zip and ftp it to the backup site (all in a script).

Unfortunately the compression part takes a massive amount of RAM (far exceeding the 378MB), it goes for the paging file and brings absolutely everything to a crawl and literally takes 2-3 days, if left unattended. So to fix this, I have to shutdown the VM, give it temporarily 768MB of RAM and then the whole thing finishes in 20 minutes.

So, is there a way do the following automatically from the host machine in a script?

  1. Shutdown the guest OS (I think, I got this part)
  2. Change the RAM allocation from 378 to 768
  3. Start the guest OS again

then, 1 hour later, do everything in reverse.

Edit: thx to Wesley 'Nonapeptide' for the links. I cobbled up a script and it works like butter. It takes the memory amount as a parameter. Here it is for any folks who might want to do this:

if Wscript.Arguments.Count = 0 then 
  Wscript.Quit
end if

memory = Wscript.Arguments(0)

Set objVS = CreateObject("VirtualServer.Application")
Set objVM = objVS.FindVirtualMachine("vbRad.com")

Set objGuestOS = objVM.GuestOS 
Set objTask = objGuestOS.Shutdown() 
objTask.WaitForCompletion(600000)

objVM.Memory = memory 

Set objTask = objVM.Startup()
objTask.WaitForCompletion(600000)

I know that where I have worked, I have pushed alot for virtualizing our servers.

I think that it is much easier to implement and maintain than physical servers.

I have been using Microsoft's Virtual Server 2005 R2 since it was released. Right now at my workplace we have 12 VMHosts that hold about 55 VMs. We have 6 other servers that we have been unable to convert to VMs.

I want to know how other people in our field view virtualization. I know that I have had developers dislike the notion of VMs claiming major performance hits.

What do other Sys Admins think about virtualized servers?

Since upgrading to Internet Explorer 8 I've been getting JavaScript errors when performing certain functions (like "Turn On") on the Virtual Server 2005 Enterprise R2 SP1 Administration Website:

Message: 'document.getElementById(...)' is null or not an object
Line: 4
Char: 1
Code: 0
URI: http://myserver.mydomain.local:1024/VirtualServer/VSWebApp.exe?view=1

Are there any workarounds to this problem other than using another browser?
