#268 fixed 100% CPU usage with Windows 2000 as guest and then shutdown Paethon
Description

When I am using a program in Windows2000 which runs as a guest in VirtualBox often one of my two cores gets absolutly blocked (100% CPU usage and win2000 gets real slow) but when I open the taskmanager in Win2000 there isnt any CPU-usage and even when I close the program the cpu-usage often (but not allways) stays at 100%

And after a few Minutes I can see a BlueScreen for a very short time (< 1 second) and then the virtual machine is closed with the status Aborted in the VirtualBox-GUI

I am running VB with Ubuntu 7.4 as a host.

#5131 fixed 100% CPU usage with x64 Win7 host, x32 WinXP guest and >1 CPUs ServerAlex
Description

I'm running Windows 7 x64 as host with VBox 3.0.8 PUEL. PC is a notebook with AMD Turion X2 TL-60 and 4GB RAM.

Guest is Windows XP 32-bit. When I enable 2 virtual CPUs, the VBox produces 100% CPU usage on the host, even if the guest is idle. The usage is kernel-mode, so even the mouse is lagging very heavily.

1 virtual CPU doesn't have that problem.
