Windows 7 Guest Guru Meditation 1155(VINF_EM_TRIPLE_FAULT)

[imhaeyong]

I exported an appliance(.ova) to a new computer. Before I imported, that virtual box could work perfectly in the old computer.
But After I successfully imported this new VM, I can enter into the Windows 7 system and could see the Deskopt.
Only After a few seconds, a message box pops up ''A critical error has occurred while running the virtual machine and the machi execution has been stopped."
I attached the log files.
Thanks in advance if you could help me to resolve this issue.

Superfluous third party AV detected: Trend Micro.

Also, I noticed that you chose a Win7-32bit template and then allocate 6GB RAM to it. Win7-32bit supports a maximum of 4GB RAM.

And I would reduce the CPU allocation to 2 cores.

The log contains notations about timers that I don't recognize...

The 6.1.0 Guest Additions you have currently installed are rather old and are also the ".0" release from that branch. Not a great choice.
But hopefully you read the 7.0.12 discussion topic and will not make the mistake of installing the 7.0.12 Guest Additions into a Win7 guest.

Hi Thanks for your reply. I changed the memory to 4GB and 2 processors and uninstall the guest additions. Still got the same result.
However, by entering the SAFE MODE, there is no error at all. Could you please give hints about this? Attachment today's VM Log.

The fact that it runs in safe mode tells you it's a driver problem of some kind. Possibly due to a hardening problem.

Also you have a version mismatch between the extension pack and the host software (7.0.4 vs 7.0.12). This should not cause the crash, but it should be fixed anyway.

You get a triple fault quite early in the boot process. IME this usually means some kind of corruption of the boot disk VDI file.
