I'm guessing that your core2duo doesn't have a VMX preemption timer, and this has some subtle effect on how the alarm interrupts VMX non-root operation. On the i7, try setting the module parameter preemption_timer to 0.
Hi again. I wrote a reliable test-case to check your suggestion. Unfortunately, no luck on I7, even with --- $ cat /sys/module/kvm_intel/parameters/preemption_timer N $ cat /sys/module/kvm_intel/parameters/unrestricted_guest N --- But the Core2 owners reproduce the problem immediately using my test-case: https://github.com/dosemu2/dosemu2/issues/1500#issuecomment-867221736 The test-case: https://github.com/dosemu2/dosemu2/issues/1500#issuecomment-867215291 The source of it: https://github.com/dosemu2/dosemu2/issues/1500#issuecomment-867215913 Now the question is: can anyone from that list please replicate our setup and reproduce the problem on Core2 CPU, and then fix it? I myself do not have such CPU, so I probably can't do that on my own.
