I see this problem with a x86 sles10 guest running on x86_64 intel host. If the guest is reset abruptly and rebooted, some where before grub sequence it hangs and the following message is seen in the logs emulation failed (pagetable) rip 7ed5 66 60 ac 20. I located this instruction sequence in isolinux.bin on the iso ;if that is relevant. I did some analysis and find that there is an ept violation, which is handled and then the next instruction '66 60' is attempted to decode and emulate. But decode fails. kvm continues loops in the kernel in __vcpu_run(). the code path is kvm_run() -> __vcpu_run() -> vcpu_enter_guest() -> kvm_handle_exit() -> handle_ept_violation() -> kvm_mmu_page_fault() -> emulate_instruction() -> x86_decode_insn() Any insights here on how to fix the problem is appreciated. And if a fix already exists even better :) thanks, RP -- To unsubscribe from this list: send the line "unsubscribe kvm" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
