Hi,
I have a server dual xeon quad core with gentoo and qemu:
app-emulation/qemu-kvm-0.12.3-r1 USE="aio gnutls ncurses sasl vde -alsa
-bluetooth -curl -esd -fdt -hardened -kvm-trace -pulseaudio -qemu-ifup -sdl
-static"
There is a lot of vm running with ubuntu and fedora that running without problems.
I installed one vm with latest gentoo amd64, stage3 and portage.
When I try to do an emerge -e world the process freeze after a while, any time
in differente package and there aren't any errors in the logs.
This is a screenshot of the freezed vm:

I found the same problem with
gentoo-sources-2.6.32-r7,2.6.33,2.6.33-r1,2.6.33-2 always with -smp 2, 4 or 6.
Kernel .config:
http://pastebin.org/252943
With 2.6.32-r7 I notice the emerge will freeze after a lot of compiled
packages, while with the 2.6.33 series after 30-40 compiled packages, emerge
freeze.
If I run vm without -smp there aren't any freeze of emerge.
In the same server there are other VMs with ubuntu and -smp 6 and works
without any problems.
There is a limit max cpus for -smp ? for the total of the VMs running in the
server?
Any suggestions?
It's possible to enable a log for what service?
Best regards,
Riccardo

There are almost impossible to debug.
Try copying vmlinux out of your guest and attach with gdb when it
hangs. Then issue the command
(gdb) thread apply all backtrace
to see what the guest is doing.

Do not meddle in the internals of kernels, for they are subtle and quick to panic.

Another thing coming to my mind is sysrq. Do ctrl-alt-2 and type
"sendkey alt-print-o" (IIRC, please check the docs for sysrq letters).
That should give you a backtrace for stuck cpus. If that doesn't help,
go with dumping the state of all processes. For easy dumpibg, boot the
guest with -serial stdio and pass 'console=ttyS0' on the kernel
command line.

Hi,
I compile gentoo-sources-2.6.31-r10 and with this kernel "emerge -e world"
complete without errors!
I always use the same .config
After I try gentoo-sources-2.6.34 and vanilla-sources-2.6.34 but the problem
remain, the compile freeze and I see this in ps -elf:

All in wait?
After this test I reboot in 2.6.31-r10 and I complete emerge -e world
succefully.
The problem show always with all kernels >=2.6.32
I have setup something wrong in kernel? I post the .config in the previous email.
Best regards,
Riccardo

Interesing. Can you so a git bisect to see where it stops working?

I have a truly marvellous patch that fixes the bug which this
signature is too narrow to contain.

Yes, I always used virtio.
In the server the kernel is sys-kernel/gentoo-sources-2.6.33
and in dmesg I see this new lines about clock?:
[ 885.500098] CE: hpet increasing min_delta_ns to 15000 nsec
[ 1354.020020] CE: hpet increasing min_delta_ns to 22500 nsec

Do you think it's a related issue with the system freeze under compiling with
newer kernel?

That's what we're trying to find out.

I have recompile gentoo-sources-2.6.34 without kvm-clock:
# cat /sys/devices/system/clocksource/clocksource0/current_clocksource
tsc
# dmesg | grep clock
[ 0.000000] hpet clockevent registered
[ 0.661050] Switching to clocksource tsc
And with this kernel all working fine! (emerge -e world)
It's a problem in the kvm-clock for kernel >=2.6.32

Can you provide the traces with kvmclock enables so we can see what went
wrong?
