Alup

I had the same problem, switching the machine to i440fx-3.1 and disabling virtualization in the VM settings. After I did this my CPU dropped from 99% all the time to 30%. Not sure if this will fix the issue for everyone but it sure did for me.

I made one for the C2100 its not as "artistic" as the ones posted here but whatev's. I took the above image from the manual and then removed all the arrows and stuff. Here is a "Front" view of the server if someone wants to make a proper icon. Well.... So I decided to just make one. I am not good at this but here it is.
