1160	High host CPU usage when running Secunia PSI on Windows guest	oudalrich		I use VirtualBox 1.54 on a Ubuntu 7.10 host. When [https://psi.secunia.com/ Secunia Personal Software Inspector (PSI)] runs on the guest, I get a constant CPU usage of around 75% to 100% on (one core of) the host, but only 2% on the guest. As soon as I end PSI, host CPU usage is down to about 10%. When I run PSI again, the host CPU is back at 75% - 100%.	defect	closed	VMM	VirtualBox 1.5.4	fixed	Windows guest, CPU usage		other	other
