Hi, In our today's testing, we still met the issue below. 1. Xen0 hang when destroy VMX guest http://bugzilla.xensource.com/bugzilla/show_bug.cgi?id=3D981 And found one more performance issue on IA32e: 2. Performance of HVM guest downgraded much. Compares with cset 15017, kernel build on HVM against 15072 downgraded about 35%. And even the execution time of our nightly testing has been doubled. We suspect the 1th issue is related with gcc version. We found the issue on the binary compiled with gcc 3.4.3. If uses gcc 4.1.0, the problem will be gone.
