Need of commandline to start VM with access to shared folder. Now if I run
/usr/lib/virtualbox/VirtualBox --comment "win" --startvm "c252555c-bla-bla"
I get VM running but shared folders not mounted, and I have to go to VirtualBox GUI manager and manualy re-select sharedfolders connections. unless the checkbox automount is checked. It has no effect in commandline launch mode.
