KVM: x86: unhalt vcpu0 on reset
Since KVM: x86: do not execute halted vcpus, HLT by vcpu0 before system
reset by the IO thread will hang the guest.
Mark vcpu as runnable in such case.
Applied, thanks. I still want userspace fixed, so please resend the

Follow Avi's suggestion to handle halted vcpu's in the main loop,
simplifying kvm_emulate_halt(). Introduce a new vcpu-requests bit to

OK, easily reproducible by adding a sleep at the start of
qemu_kvm_system_reset.
The problem is that the vcpu HLT's between
