#2380 fixed VirtualBox 2.0.2 GUI hangs / stops responding to input myxiplx
Description

Over the past few days I've noticed that the VirtualBox virtual machine window will stop responding to input for several minutes, although the virtual machine can be seen to be running fine.

I can't find any bugs similar to this on the tracker, but it appears I'm not the only person noticing this as I found this post in the forums: http://forums.virtualbox.org/viewtopic.php?p=40763#40763

I'm noticing the problem at least once a day at the moment, but can't yet see any pattern as to when this happens.

#2381 fixed virtualbox 2.0.2 is unable to "reboot -f" an opensolaris snv_100 guest jkeil
Description

There's a new "fast reboot" feature in opensolaris build 100: http://www.opensolaris.org/os/community/on/flag-days/pages/2008092201/

Problem: virtualbox 2.0.2 is unable to "reboot -f" an opensolaris snv_100 guest (64-bit and 32-bit). The guest shuts down, but virtualbox 2.0.2 guest hangs while trying to start / reboot into the new kernel.

HW: AMD64 X2 cpu, AMD-V enabled in virtualbox. Host OS: SXCE build 96, bfu'ed to current opensolaris bits (2008-10-2)

The guest hangs in fb_swtch_src.s when the kernel switch page tables are installed.

http://src.opensolaris.org/source/xref/onnv/onnv-gate/usr/src/uts/i86pc/ml/fb_swtch_src.s#209

usr/src/uts/i86pc/ml/fb_swtch_src.s:

   209          /*
   210           * Load top pagetable base address into cr3
   211           */
   212          movl    FI_PAGETABLE_PA(%esp), %eax
   213          movl    %eax, %cr3
   214
   215          movl    %cr0, %eax
   216          orl     $_CONST(CR0_PG | CR0_WP | CR0_AM), %eax
   217          andl    $_BITNOT(CR0_NW | CR0_CD), %eax
   218          movl    %eax, %cr0

Workaround: Boot Solaris guest with "-B disablePAE=true", and strip the PAE feature mask (0x200) from the kernel variable x86_feature.

#2382 fixed Host OS freezes, and only works during mouse movement yaku
Description

When I start a Windows XP virtual machine, the system comes to a complete halt - BOTH the Ubuntu host and WinXP guest. Nothing happens on the screen, nothing happens in general unless I move the mouse. When I stop moving the mouse, everything stops again. So basically the system is unusable until I quit VirtualBox (sometimes the problem stays even after the virtual machine is stopped, requiring a reboot).

This does not happen every time, but more often than not. I did not have this problem with the VirtualBox OSE version available in the Ubuntu Hardy repositories.

Some system details I thought might be relevant:

  • VirtualBox: 2.0.2 closed source edition (taken from virtualbox home page)
  • Host OS: Ubuntu Hardy Heron 8.04 32bit.
  • Host OS kernel: 2.6.24-21-generic (from hardy proposed repositories maybe)
  • Guest OS: Windows XP Pro SP2, latest Guest additions installed (virtual machine was created with VirtualBox OSE 1.5, and updated by the current virtualbox installer)
  • Machine: Acer Ferrari 4000 laptop (ATI graphics, AMD Turion64 processor) (at boot time there has always been a message like "BIOS bug: Timer not connected to IO-APIC", I wonder if it could have something to do with this)
  • Compiz is installed but not in use.
  • I have two mouse devices (wireless and wired, both USB)
  • Latest EnvyNG ATI proprietary graphics drivers installed
  • I have an external LCD screen in clone mode connected via DVI
