VirtualBox randomly runs the processor at 100%

We have a Windows 2012 server with an Intel Xeon E5-2430L v2 @ 2.4GHz and 32GB of RAM. One of our other servers died so I setup Oracle VM and created a virtual machine out of our backup (from Shadowprotect). The virtual machine is running Windows Server 2003 Enterprise Edition.

The virtual machine will run GREAT for about a week (haven't had enough time to figure out if there is any consistency) then it will all of a sudden be using 100% of its own resources and I can never get it to stop. The last time this happened I created a clone and then ran that and it worked for about a week.

I have Process Explorer installed but I don't see one process stealing all the CPU usage.

I will attach a screen shot once it comes back up - been waiting 20 minutes now.

Any  suggestions?

I wanted to clarify, The VM itself is what is hitting 100%. The new server has almost no load.

I'm attaching some screenshots from the VM.

WHY?

Why not add the Hyper-V role?

and have a proper Type 1 Hypervisor?

The issue could be wrong Windows 2003 HAL ?

Are you using multi processors ?

The honest answer to WHY? is because that was the only solution I could come up with at the time - and Shadowprotect made it easy to boot into this type of VM. I don't know much about Hyper-V role, etc.

Currently we are using one processor. If I increase it to 2 or 3, the VM doesn't seem to like it.

Can I convert my current VM?

Thanks in advance!

What is the HAL?

What was the physical server?

If you are using a Multiprocessor HAL on a single vCPU server, it will cause this issue.

I hadn't considered or really ever used Hyper-V but after this suggestion and some digging around I was able to convert my Virtualbox image over and its running great!
