Intel and AMD have provided hardware support, VT and SVM, to support classical full virtualization. The hardware extensions help to implement a VMM without changing the guest OS or resorting to software binary translation. Ironically, a VMM using VT or SVM has not yet met performance expectation. One major reason is that there still exist too many VM exits that incur significant overhead. This paper proposed a novel method, Competition in Bucket Method (CBM), to track all VM exits efficiently. The analysis and experiments show that, CBM can find out hot VM exits efficiently. © 2010 IEEE.
