i installed a new Windows 2008 Server on VirtualBox 4.2.12r86644 and prepard the Installation with sysprep. then i mark the disk as immutable.
then i create a new Server and attach the immutable disk. when i start the machine, a snapshot disk will be generate automaticlly. but when i shutdown the machine, all changes are lost ... when i start the machine the snapshot disk is empty.
how can i save the snapshot disk?
i should install 5-10 virtual machines with the same configuration. but (when it´s possible) i don´t want to copy the masterdisk x times.
(no discussion about Performance
... i should configure a "Little" Cluster in a lab to get a look&feel for all Settings)best regards
