Summary: KVM crash with Windows XP guest because of ACPI
Initial Comment:
Host: Fedora7, 64-bit, Intel CPU, KVM-48.
When I start Windows XP guest, that was installed with ACPI enabled, without

This patch can now execute guest userspace (I'm not saying it's complete
or stable or anything though). I need to put together a more
full-featured ramdisk to test userspace more completely.
Congratulations Hollis, cool stuff :-).

Is there a possibility to check, if CONFIG_PREEMPT_NOTIFIER correct selected

Hello All,
I have a Qemu image running WinXP. I originally set it up to use User Mode
Networking with Qemu under Ubuntu 7.04 Feisty Fawn on a non-VMT-capable
system.
I am now running a dual-core, VMT capable system using Ubuntu 7.10 Gutsy
Gibbon.
I installed KVM and my virtual machine image
This patches can be applied only on kvm-updates-2.6.24 and kvm-updates-2.6.25
as it needs smp_call_function_mask().
In kvm_flush_remote_tlbs(), it replaces a loop using smp_call_function_single()
by a single call to smp_call_function_mask().

Common code could figure whether or not it needs to save/restore the

As vmx_create_vcpu already makes use of start/end_special_insn, we need
to initialise the emulated preempt_notifier earlier. Let's move it to

during kvm startup - so far the problem did not show up again.

Hi,
I'm seeing fairly high vm-exit latencies (300-400 us) during and only
during qemu/kvm startup and shutdown on a Core2 T5500 in 32-bit mode.
It's most probably while the VM runs inside bios code. During the rest
of the time, while some Linux guest is running, the exit latencies are
