VB 5.0.x keeps crashing XP and W7

[pws442]

My Macbook Pro is running El Capitan! (16GB RAM)I used 4.3.30, and had no USB devices. So, I upgraded to 5.0.6, and had USB devices, but then, EVERY time I entered the Windows XP/W7 password, it would Abort. I went back to 4.3.20 and lived w/o USB. I saw 4.3.32, but it still does not show USB devices. Saw 5.0.8, and tried it, but the crashes continued. Would appreciate any help! (I have a couple W7 logs attached.)

P.S. Is there going to be revisions to 4.3.x so VB will support USB in El Capitan?)

Why is there two logs? What do they each represent?

[pws442]

They are two successive crashes. I thought it might help.

VBox 4.3.x dos not support El Capitan. It might work but there is no guarantee. Please switch to VirtualBox 5.0.8.

Sadly there is zero actionable information in the logs. They are just incomplete logs, no evidence of anything going wrong.

Sorry, I didn't see that you tried 5.0.8 already. I fear we need to be able to reproduce this problem. Or can you provide a core dump? See here.

If it were my MBP, I would try reducing the guest's RAM to 2GB, increase the VRAM to at least 128MB or disable 3D acceleration. Trying to run OSX 10.11 and Windows 7 as a guest may be inherently problematic on a Core 2 Duo CPU, 2 cores, no hyperthreading etc. Of course without a complete log it's hard to say.

The lack of nested paging on Core 2 is a serious performance killer for virtualization, too.

Here is what I have done:

First, I lowered the RAM from 3370MB to 2048MB and Disabled 2/3D Accelleration. Same results: soon as I enter password in W7, it crashes.

Next, I opened Terminal and tried: $ ulimit -c unlimited, followed by: $ VirtualBox. Came up and wanted the Guest Additions, which I installed. It restarted just fine. Shut the VM down, restarted fine. Shut down, Quit VB. Restarted fine. Repeated. 2-3 times later it crashed after the password.

Now, I just used Terminal to restart it, and it came up okay. Next time, not so good. It crashed.

I was not very good at the Core Dump. I used Find Any File to search for the /cores folder, but when it Revealed in Finder, I could not see it. Not sure what to do now regarding a core dump.

Help!

I found the cores.1412 file, but it is 3.2 GB. I am going to delete it from the SSD. If there is a particular piece of it, and someone can tell me how to extract it, I will.

Does this still happen with VBox 5.0.10? If so, I would be very interested to see the core dump. Perhaps compress it and upload it to a server and then telling me the location?
