Abstract
A method for improving accuracy of high resolution timers in a live partition migration comprises determining a status of each page of a plurality of pages to be copied from a source partition to a target partition during the live partition migration. One or more pages of the plurality of pages correspond to a respective high resolution timer. The method comprises determining that each of the one or more pages corresponding to a respective high resolution timer has a clean status. A clean status indicates that the corresponding page has been copied to the target partition and has not been modified subsequent to being copied to the target partition. The method also comprises halting operation of the source partition and initiating operation of the target partition in response to determining that each of the one or more pages corresponding to a respective high resolution timer has a clean status.
