High CPU usage and guest crash
|Reported by:||jauss||Owned by:|
first, I have a windows XP SP2 with VBox 1.5.6. The problem occurs with 1.5.4 too. I have crashes on windows guest start-up, even during installation. I cannot use VBox. The problem may come from my system, but I have not clue about the cause. I tried to uninstall and reinstall VBox, different version, but still the same problem. Find attached the logs file.
Another issue: Having a windows guest cause HIGH cpu load: 1 full core per virtual machines: 50% cpu usage cause I have a Intel dual core CPU.
Setting the CPU affinity of the virtual machine (virtualbox.Exe) to CPU 0 fix the problem immediately, but not on CPU 1 on witch the problem remain.
I tried with virtual box 1.5.4 and 1.5.6 with the same problem. Note that I have no problem using the same virtual machine on a single core computer, or if i disable the dual core on my host computer.
Hope somebody can help.
