Yes, regarding AHCI it works! But assign_pci fix does not work, two constructors requires more parameters than existed in this patch (namely, lines 166 and 759 in pci_session_component.h).

Side notes:
1) My previuos attempts with USB stick were not fully successful: it seems that usb_drv not always correctly writes data, because after second opening of "/" from disk/not from cache (while vbox should rewrite *.vbox file) rump panics ("mangled entry"). So that stick is one-off, so to speak.
2) It would be nice to have system-wide "shutdown" procedure, at least for unmounting purposes.

Thank you for help!
