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?
Shutdown the guest OS (I think, I got this part)
Change the RAM allocation from 378 to 768
Start the guest OS again
then, 1 hour later, do everything in reverse.
