Hi,

In the ProcessWMIJob function, when $Result.ReturnValue is not 0 or 4096, you throw. How can we map $Result.ReturnValue to a meaningful description of the error (other than just "job failed") ?

thanks,

Marc

Marc,

I am working on a post for latter this week to talk about this problem - and hopefully a good solution to it...

A stop gap is to look at the windowsvirtualzation.mof file in system32...

I don't suppose you could post the VBScript version of these since power shell does not run on server core.

Thanks,

I had a question,

I have only one VM (not running) and when I use the query: "Select * from Msvm_ComputerSystem", it gives back the result set containing details of only the host computer system and NOT the virtual machine present. Any idea why this is happening?

Hi Your post was useful. But, i face problem in low disk space. Since, deletion of snapshot doesnt delete the differencing disks(.avhd) and they are not merged due to active running of VM. Is there a way to script turn off and after merge completes turn on the VM on deletion of snapshot?
