When I fired up my RSS reader today I notices a lot of new/updated KB articles at VMware’s site about timing in virtual machines. I figured it’s worth while to link them here just in case.
- Determining and changing the rate of timer interrupts a guest operating system requests
- Time in a Linux virtual machine jumps backward when using clock=pit
- Time runs slower than real time due to lost timer interrupts
- Time in a Linux 2.6 guest operating system runs faster than real time due to lost tick overcompensation
- Time in virtual machine drifts due to hardware timer drift
- Time runs too fast in a Windows virtual machine when the Multimedia Timer interface is used
- Time falls behind in a virtual machine when the memory of the virtual machine is paged from disk by the VMkernel
- Time drifts in virtual machines and the service console due to the HPET misreporting its frequency
See that is a lot of them. Please read them, commit them to memory, there will be a quiz later
