I have created a VM image out of a physical PC running Windows XP. I am now trying to run that image as a guest OS under Ubuntu Linux using VirtualBox. Everything seems to be running smoothly with the exception of one issue:
The performance of the guest OS is extremely slow, and it shows extremely high CPU usage to complete even simple tasks like opening up a dialog box.
One thing that I have noticed is that when I right click on "My Computer" and go to "Properties" in the guest OS, it shows the CPU information as follows:
Pentium (D) CPU 2.80Ghz 3.95Ghz, 896MB RAM
Now the intriguing part here is that the Pentium D 2.8Ghz processor is what the host machine is running, but I have no idea what the 3.95Ghz is about. I should also note that the 3.95Ghz during a previous boot of the image read something along the lines of 5.2Ghz!
I'm thinking there is a processor issue here. Does anyone have a solution? I have already tried uninstalling the processor in the Device Manager and rebooting, which didn't fix it.
