Workaround for VirtualBox 4.0.8 regression bug

2011/05/25 Comments off

The current version of Oracle’s VirtualBox (4.0.8) has Version 4.0.8 had a regression bug which seems to only manifest itself when using Debian based hosts with 64-bit and Windows 7 64-bit guest system.

Here is the summary of the workaround posted as VirtualBox Ticket 8948:

  1. Edit the settings file to allow the VM to start again (Replace control characters in line 315 with 4.0.8).
  2. Start the Windows guest
  3. Run regedit
  4. Go to HKLM\SOFTWARE\Oracle\VirtualBox Guest Additions
  5. Create a string key VersionEx (use exactly this spelling)
  6. Give it a reasonable value (ie 4.0.8)
  7. Shut down the VM.
  8. Repeat step 1
  9. Restart and shutdown windows guest again
That’s it.
Edit: This bug has been fixed in version 4.0.10 (released 2011-06-27).

Configure VirtualBox Windows guest system to use 2 monitors

2011/01/01 Comments off

Purpose

Our host system for VirtualBox is GNU/Linux. We want our guest system, windows, to use two monitors.
This solution should work for all Linux distributions supported by VirtualBox4.

Required software

  • Ubuntu 10.10 (aka Maverick) as host for VirtualBox4
  • VirtualBox 4
  • VirtualBox guest sytem: Windows XP (incl. VirtualBox guest additions)

Configuration

  1. Setup virtual guest machine (windows) within vm host system (GNU/Linux) to use two monitors:

    virtualbox-host-ubuntu-10.10

    Setting up virtualbox 4 to use 2 monitors for windows xp guest

  2. Within virtual guest (windows): Configure dual monitor setup:

    virtualbox_dualmonitor_windows_config

    Setup within virtualbox guest system (windows)

Side note

Upgrading from VirtualBox owned by Sun to VirtualBox owned by Oracle was very smooth. Even for Linux host systems. Oracle, thanks for that!
