WinXP freezes after installing TwinCat

[two]

After installing ​TwinCat the system freezes after booting once the desktop is loaded, but only if VT-x is deactivated. If VT-x is active, the system runs stable, but at 50%-80% CPU load, even if the guest is idle.

Running on Intel Dual-Core, WinXP32 Host, WinXP32 Guest (both running SP3). Default settings for VB with RAM set to 512 (with 2GB available).

Tested this with 1.6.4 and the problem persists. Even if the guest reports 99% idle, the CPU load of the VM-Process is at 50%-80% CPU load as soon as TwinCat is turned active.

Please note that this is not a TwinCat specific problem, but hints a general VM-Error/Problem.

Not possible to use VT-x
