hi,

i'm running VB 3.1.2 r56127 on a mac mini, 2,66MHZ/4GB RAM OS X 10.6.2 and had recently some problems to start my Win XP VM.

didn't use the Win XP VM for a while and so used still VB 3.0.6 as i started it up several weeks ago. but surprisingly the machine won't start telling me instead something about "failure to start usb subystem". as i hadn't done an update for a while, i updated to 3.1.2 r56127, started the Win XP VM and it booted sucsessfuly. fine, i thought. problem solved.

again i didn't use windows for a time, and as i tried to start it up some hours ago… guess what:

a window opened to tell me:

"Virtual machine 'win' has terminated unexpectedly during startup.

Fehlercode:
NS_ERROR_FAILURE (0x80004005)
Komponente:
Machine
Interface:
IMachine {99404f50-dd10-40d3-889b-dd2f79f1e95e}"

another window opened:

"RTR3Init failed with rc=-1912 (rc=-1912)"

i tried to access the machine configuration, and yet another window opened:

"Kein Zugriff auf das USB-Subsystem.
Could not load the Host USB Proxy service (VERR_GENERAL_FAILURE)."

so…. i reinstalled VB 3.1.2 r56127, started XP and it booted again successfully. i repeated that several times and everything was fine. i logged in and out of my user account. and still XP started without problems.
then i restarted the mac, opened VB, started XP.. and got the same errors again. no XP
reinstalled VB. XP works. restarted the mac. XP fails with the same errors

any ideas?

xcuse my english. not my first language

Check the following topic http://forums.virtualbox.org/viewtopic. ... led#p84945, especially the part at the end about the VBoxDrv.kext.

oh.. that was fast.

thank you

i will try that solution and hope, that the kext will stay in place after a reboot.

works

extension stays in place even after a host reboot, when you copy it manually into the extension folder.

XP now works fine.

thx
