Наконец, после некоторой борьбы, я получил его полностью работающим, и вот рабочий код: Это создает виртуальную машину - GUID, имя и состояние. Можно использовать Msvm_SummaryInformation или Msvm_ComputerSystem. Я предпочитаю Msvm_SummaryInformation, поскольку этот класс имеет более подробную информацию. Я использовал этот пример и построил на нем. Больше никаких PS для меня :)
