A VM image can be attached to any VMs but one VM at a time; multiple

We encontered problems with the low default value for the stacksize in usermode
(ok, whats "low").
For environments like scratchbox, its hard to use "-s" as qemu is called by
binfmt mechanism.
The attached patch makes this configurable at compile-time.
