last command in script may fail, but it is not a problem.

Much easier to debug.

It's not a bug, it's a feature.

Sometimes we want a second disk even inside of VM.
Even weirder, maybe you want a vm inside of your vm (now possible with new KVM).

No need for endscript.

Only ask bridge question if it is not a VM.

This reverts commit 57e0868a.
