I intercepted the #UD exception and printed out the opcode. This opcode was all zero in the first time and changed randomly to other undefined values. I also saved the last exit code before the UD intercept and that was a PF intercept. The guest is in 32 bit PAE mode when this happens. Regarding this research I assume this bug is not SVM related, I think something in the MMU goes wrong here. Joerg -- Joerg Roedel Operating System Research Center AMD Saxony LLC & Co.
