[Linux-cluster] Parameter snapshot in vm.sh

[Dirk H. Schulz]

Hi folks,

in vm services there is a parameter "snapshot=PATH" which in vm.sh is 
explained as "Path to the snapshot directory where the virtual machine 
image will be stored".
I do not understand this as the virtual machine image is stored wherever 
it is configured in the virtual machine config file - and what does it 
have to do with snapshots (i. e. what is a "snapshot directory")?

Any hint or help is appreciated.

Dirk
