QueryPerformanceCounter behaves improperly inside a virtual machine when /usepmtimer is used with some Windows HALs (1011714)
A Windows guest may experience these symptoms:
- QueryPerformanceCounter stays within a 4.7 second range, advancing at the correct rate for ~4.7 seconds, then jumping back 4.7 seconds
- Applications stop responding
- Negative ping times
This issue is resolved for Windows 2003 in vSphere 5.0 Update 1. However, the issue still persists in Windows XP.
To work around this issue, avoid specifying /usepmtimer in the boot.ini file when using Windows 2003 or Windows XP with an SMP HAL.
