KVM: x86: fix possible infinite loop caused by reexecute_instruction Currently, we reexecute all unhandleable instructions if they do not access on the mmio, however, it can not work if host map the readonly memory to guest. If the instruction try to write this kind of memory, it will fault again when guest retry it, then we will goto a infinite loop: retry instruction -> write #PF -> emulation fail -> retry instruction -> ... Fix it by retrying the instruction only when it faults on the writable memory Signed-off-by: Xiao Guangrong <xiaoguangrong@linux.vnet.ibm.com> Signed-off-by: Avi Kivity <avi@redhat.com>
