I removed the kvm/kvm-intel modules. qemu command line was:

First boot has been working fine since your patch this past weekend. It's been
subsequent boots that hang.
I added -no-kvm-irqchip to qemu command line and did not add the noapic boot
option: it's hung at 'Starting udev' again but this time it's not consuming
CPU. kernel stack traces for qemu t

First reboot or first boot?
I thought the problem was cold starting a VM.

I let the host stay up for 90 minutes before loading kvm and starting a VM. On
the first reboot it hangs at 'Starting udev'.
I added 'noapic' to the kernel boot options, and it boots fine. (Turns out I
only added that to grub.conf in images that run a particular ap for which I am
running perfor

With kvm-52 my 32-bit host running RHEL5.1 can start an RHEL 5 SMP guest only
once. Second and subsequent attempts hang. Removing kvm and kvm_intel modules
have no affect; I need to reboot the host to get an SMP guest to start. My

Excellent. I had a premonition so it is already committed.
Do note that smp_call_function_mask() emulation is pretty bad in terms
of performance on large multicores
The patch worked for me -- rhel4 smp guests boot fine on stock RHEL5 hosts,
both 32-bit and 64-bit.

that would be really sad, since what i like in kvm that i don't have to
compile kernel, so be able to follow upstream kernel updates:-(((

I found that I had to move to a newer kernel (2.6.23.1 is what I used) to get
SMP guests to boot on RHEL5 hosts. It appears to be an issue with the host
kernel.

This isn't new. It isn't reported because few people run smp Windows,

You mean the guest hangs, right? What'
First , thank you for new release of kvm. I have a few problems to
report with kvm-51.
1. When running an exisiting winxp ACPI multiprocessor HAL with -smp 2,
sometimes it will hang on boot.
2. This may not be a major problem but cpu usage is a litte higher when
idle on release 51 than 50. It
If you're having trouble on AMD systems, please try this out.
Changes from kvm-50:
- fix some x86 emulator one-byte insns (fixes W2K3 installer again)
- fix host hangs with NMI watchdog on AMD
- fix guest SMP on AMD
- fix dirty page tracking when clearing a guest page (Dor Laor)
- more portability
