Hello.
Dominik Klein (Cc'd) reported on irc that current
FreeBSD release hangs at boot in qemu-kvm. It is
trivially verifiable by d/loading the bootonly
FreeBSD 8.2 CD image from ftp.freebsd.org and
running
kvm -cdrom FreeBSD-8.2-RELEASE-amd64-bootonly.iso.
The guest unpacks kernel, draws a menu (apparently
in real kernel already, not in the boot loader) and
starts a 10-second countdown. At this point it just
stops (either at 10 or 9, ie, right at the beginning
of the cycle) and kvm process starts using 100% of
the CPU core given to it. With this typical kvm_stats
from qemu-kvm 0.14:
kvm statistics
exits 43397783 1400960
halt_exits 42862622 1400769
irq_exits 5487 172
host_state_reload 300074 101
io_exits 292212 18
irq_injections 768 18
halt_wakeup 257 3
mmu_pte_write 7702163 0
insn_emulation 378273 0
mmio_exits 15786 0
pf_fixed 4817 0
mmu_shadow_zapped 170 0
mmu_cache_miss 151 0
remote_tlb_flush 2 0
signal_exits 1 0
fpu_reload 1 0
I tried i386 and amd64 guest images, and tried the same
thing with qemu-kvm 0.12.5 and 0.14.0 - the effect is
exactly the same.
So far the 3 affected systems where we tried this are all
AMD machines. My home box is AthlonII, my work box is
PhenomI 9750, and Dominik tries it on Opteron 6174.
Running it with -no-kvm lets the guest to go (but obviously
very slow). Using -no-kvm-irqchip helps too.
Any guess what it can be?
Thanks!

Can't reproduce. What host kernel version are you using?
Please post the output of
info register
x/50i $eip-30
on the qemu monitor.

I also tried on another AMD machine, with TurionI, -- the same
effect.

And this is a very good question, this is what I forgot to
mention.
It hangs here - in all cases - with 2.6.37+ kernels. I
tried 2.6.35 on one of my boxes, and there it works just
fine. We're testing various kernels now, or trying to.
So I'm not sure anymore it's actually AMD-specific, but at
least one person tried debian 2.6.37-2-amd64 kernel on
a core-i7 box and that combination works.

And this is where the most fun begins. Right after `info registers'
it "unhangs" and continues as if nothing happened, ...
> x/50i $eip-30
...so I can't get this information anymore. Here it goes with
an explicit "stop", fwiw:

Probably one of the KVM_REQ_EVENT changes. Please try kvm.git and
report, it's likely fixed.

Nope, that's not it. Applying this commit has no
(visible) effect on this hang.
I'll try kvm.git later today, hopefully.

With kvm.git kernel it works.
Here's what I did:
git clone git://git.kernel.org/pub/scm/virt/kvm/kvm.git
cd kvm
cp /boot/config-$(uname -r) .config
# set LOCALVERSION to -kvm.git.20110309
make modules bzImage
make modules_install install
# build initrd
reboot
/usr/bin/qemu-kvm -vnc 127.0.0.1:0 -cdrom
/root/isos/FreeBSD-8.2-RELEASE-amd64-disc1.iso
vncviewer localhost:0
# visually verify that it does not hang as it did before

Dominik

Please, on this kernel, run a trace per
http://www.linux-kvm.org/page/Tracing. Stop trace-cmd early so the
trace file doesn't blow up.

(Yes, this kernel works for me too).

So the trace is for a working kernel? That's not very interesting (well
maybe later to compare against).

Sorry, I misread. So kvm.git works, we just have to identify what patch
fixed it.
What's the last kernel that *didn't* work for you?

2.6.38-rc8 does not work - verified by Dominik.
But kvm.git works.
I know it warrants a very nice bisection :)

There's some chance it's e5d135f80b98b0.

If you apply it, also apply the following commit 2607b0533353c since it
fixes a bug that tends to be exposed by the previous patch.

So, the two mentioned patches on top of 2.6.37.3 makes the
problem go away, -- guest runs flawlessly with the two
patches applied. I had to apply kvm_host.h change manually
since there's one extra #define (KVM_REQ_APF_HALT) which is
not present in 2.6.37.
So.. -stable candidates, after applying them for 2.6.38? :)
Thanks!

Certainly. Thanks for testing.
