We had a very similar problem on PowerPC, and it looks like it may be the same cause for you. Basically kvm_arch_vcpu_ioctl_run() should look something like this: + if (!run->exit_reason) { if (signal_pending(current)) { run->exit_reason = KVM_EXIT_IRQ_WINDOW_OPEN; break; } + } Otherwise, you can have kvm_run all filled out for MMIO emulation, then see a pending signal and clobber it. -Hollis
