After 3.0 upgrade, XP guest hard-locks

[bsmith1051]

For the past year I've been using a WinXP-Pro SP3 image on my Ubuntu 8.10 (now 9.04) host without any issues. Ever since upgrading VB from 2.2 to 3.0, however, the XP guest keeps hard-locking at random intervals. I don't think it's lasted more than 24 hours? The only change I made was to include the DX acceleration. Is there some way to troubleshoot this?

For instance, is it possible to remove the DX support?

DirectX cam be enabled or disabled for each VM in settings through Virtualbox GUI

You aren't making use of SMP?

I'm getting these hard-locks with more than one CPU. If I configure only 1 CPU for XP then everything is ok again. Other than installing the guest additions I did nothing else such as enabling 3D support. In addition to the hard-locks I'm also noticing very bad warbling with the audio. Just like the hard-locks this goes away when configured for one CPU.

This was initially a 'v2' image so it's never had dual-cpu enabled. Also, even though I selected DX support during the VB 3.0 install it's not enabled in this image.

i might be having just the same behaviour:

Ubuntu 9, Lenovo 3000 N200 laptop, 1 gig of memory, Windows XP Pro as the guest O/S.

I fought like bloody heck to get it to boot in more than just safe mode. In regular Windows mode, It now works ok for a few minutes (sans networking) and then just freezes. I turned on task manager performance graphing just to watch and sure enough, it freezes. The cpu (via top) is pegged for the vm, so it's working hard to do nothing.

I still have all the NIC's disabled in this windows image, but that isn't related. After I get past the freeze up behaviour, I'll address getting networking to work without preventing the bootup.

Any Windoze/virtualbox gurus out there have a magic bullet?

so far the 3.0.1 upgrade has been stable so hopefully they fixed a bug that was causing my lock-ups

stepnav,
Are you saying that your laptop only has 1 GB of physical memory, or does your WinXP VM have 1 GB of virtual memory? If the former then I'd check the Ubuntu System Monitor because the Linux host-OS might be freaking-out for lack of available physical memory.
