VBox crashing on a Windows XP Professional x64 host

[joss]

Hi,

I am a user of Virtual Box and recently decided I was buying a heavy machine to make virtualization experiments.

I got a 64 bit machine with an Intel Xeon E5520, at 2.27 Ghz, and 12GB of RAM Memory. The installed operating system is Windows XP Professional x64 version 2003, Service Pack 2.

I installed Virtual Box, version 3.1.2 r56127

I installed an Ubuntu guest in a Bridge nt adapter network configuration. From time to time both the guest and the host reset. I dont have any problem when I do not use VBox. I have been using VBox without problems in other machines. In fact this machine is an imported one, which was created in a Windos XP 32-bit host and running there without problems.

I will add a dump the next time I get a crash (I just read now how to do so).

Anyone that can give me a hand on this?

Thanks in advance.

As long as you cannot provide a dump or at least a VBox.log file there is nothing we can do ...

Hi, thanks a lot. I think I have discovered what was the reason for the error:

I was trying some VoIP experience with a server and a client in my guest ubuntu virtual machine and another client in my windows 64 host. Both clients were trying to access the same sound device and apparently that caused the crash of the guest and host machines (the virtual as well as the physical, both crashed ...). I say apparently because I have had no more issues since I selected Null Audio Driver for my guest virtual machine.

Thanks anyway, receive my best regards.
