Hi all:

I'm Alec Joseph Rivera, from the Philippines and new on this list.
Anyway, I'm trying to run Lotus Foundations on kvm and it just hangs on
bootup. It stops right after:

  Checking if this processor honours the WP bit even in supervisor
mode... Ok.

There's no more output after that. My invocation line is:

  $ qemu-kvm -cpu host -m 1G -cdrom lfs.iso

Adding -no-acpi allows the bootup to progress for a little bit then
hangs again with no further error messages after:

  PCI: PCI BIOS revision 2.10 entry at 0xffe77, last bus=0
  PCI: Using configuration type 1

I tried adding kernel parameters like noapic, nolapic and pci=xxx but to
no avail. Adding -no-kvm allows somewhat normal operations but I/O
breakdowns after awhile. Kernel logs say something about dma timer
expiry. nolapic_timer on the kernel commandline seems to fix it. But no
one likes to settle with -no-kvm right :-)

I tried -no-kvm-irqchip and -no-kvm-pit separately, then together, but
they also don't have any effect. Still hangs after the WP bit checking
part.

I made some digging and found out that Foundations is actually based on
SLES 10 and uses a rather old 2.6.16 kernel. On kvm's changelog, kvm-47
already had added support for these kernels. Might this be a regression?

My host kernel is 2.6.35 and qemu-kvm is 0.12.5. modinfo kvm gives
nothing about the kvm version though..

Anyone got some suggestions I could try? BTW, kernel rebuilding is not
an option on Foundations :-(

Thanks.


Cheese!

Your host is probably too new for this old guest. -cpu host directly passes through this host cpu's identifiers on which the guest might choke. Please try again without -cpu.

Tried without -cpu, still hangs after the WP bit checking...

$ qemu-kvm -m 1G -cdrom lfs.iso

I was scanning the changelogs and read something about a
-no-kernel-irqchip. The man page doesn't say anything about it but will
try this one too..

Please try:

$ qemu-kvm -m 1G -cdrom lfs.iso -serial stdio

Then when it shows the bootloader, add "console=ttyS0" to the kernel command line. That should give all the debugging output necessary.

Already done this one too (I've read it from your conversations with a
Peter guy if I'm not mistaken).

It just stops with no panic messages right after the mentioned checking
part, which made me dig after timers (bogomips calibration should be
next I believe). But I've gotten nowhere so far...

Also, there's no -no-kernel-irqchip parameter, must have been a typo for
-no-kvm-irqchip.

Interesting. Mind to check if you find a the vmlinux binary for that kernel on the cd? Maybe it's hidden inside an rpm. Then you can use:

$ qemu-kvm -s -cdrom ...
$ gdb <vmlinux> -ex 'target remote localhost:1234'

(gdb) bt

That should give us a clue on what's going wrong.

Also, does the host's dmesg say anything?

Sure will do this. I'll update the list later this morning.

Nothing on the host's dmesg too. I've checked
{kernel,messages,syslog,everything}.log just to be safe but they're on
the clear also...

Meanwhile gotta sleep. Thanks for the help so far.

Hm.  There was some error with earlier kernels and
kvm that resulted in exactly this behavour.  Maybe
even a (guest) kernel bug.. no?  My memory is vague
in this area, but it tells there was something...

I did the steps you mentioned. Here's the gdb transcript:

There's no action, no messages after the WP bit part so I had to do ^C.
I hope that doesn't taint the debug session.

I tried running qemu-kvm without an -m parameter, the result is not that
different:

What is k12_1009? Are you sure this is vmlinux?

BTW what version on kvm/qemu are you using.

Hi Gleb:

Yes, k12_1009 is the kernel image that isolinux loads.

qemu's version is 0.12.5. modinfo kvm doesn't reveal any version string
though, however the kernel is 2.6.35 from Arch.

Question: from what I've read so far kvm versions are of 'kvm-xx' where
xx is a number, on sourceforge there is kvm-kmod-{kernel-version}, am I
correct in assuming and saying then that my kvm version is 2.6.35?

Thanks...

This is bzImage, You need corresponding vmlinux bzImage was created

kvm-xx is deprecated. So when asked what kvm are you using you should
provide your kernel version like you did.

Oh I see. Thanks for pointing that out. Unfortunately, I don't think I
can get that image. Either I ask someone from Novell or IBM.

I'll try crawling the system's filesystem, maybe I can find it there...
Will keep you updated.

Hi Michael:

I suspect has something to do with loops (re: bogomips calibration) or
timers (re: calibration + pci probing). Will verify this when I get the
time to read the source.

Maybe someone more familiar with this kernel area can shed some light on
the topic too...? :-) only if I'm not stretching too much..

boot with param lpj=xxx to avoid calibration

copy xxx value from your normal boot kernel messages

Hi Dave:

Crossing out calibration, added the lpj parameter (and combinations with
-no-hpet and -no-kvm-irqchip) but still hangs after WP bit checking.

This looks odd. Why would anything be in non-kernel here?

This looks like a bug I also have seen recently on 32 bit host-kvm. The
instruction emulation for 'lock cmpxchg8b' was broken so that the rip
was not advanced and the guest just iterated over this instruction again
and again. I thought this was fixed with the latest kvm updates in
2.6.36.

Will wait for a 2.6.36 kernel then or compile a .36-rc myself on free
time :-)

Thanks, will update the list when either comes.

Just checked, 2.6.36-rc4 contains the fix for the cmpxchg8b problem on
32 bit hosts.

What commit it is?

I swear I saw it in 2.6.32-stable somewhere.  Is it this one (2.6.32.12):

From: Gleb Natapov <gleb@redhat.com>
Date: Fri, 19 Mar 2010 15:47:31 +0100
Subject: KVM: x86 emulator: fix memory access during x86 emulation
To: stable@kernel.org
Cc: Marcelo Tosatti <mtosatti@redhat.com>, Avi Kivity <avi@redhat.com>, Gleb Natapov <gleb@redhat.com>
Message-ID: <1269010059-25309-4-git-send-email-stefan.bader@canonical.com>


From: Gleb Natapov <gleb@redhat.com>

commit 1871c6020d7308afb99127bba51f04548e7ca84e upstream

Currently when x86 emulator needs to access memory, page walk is done with
broadest permission possible, so if emulated instruction was executed
by userspace process it can still access kernel memory. Fix that by
providing correct memory access to page walker during emulation.

it is 16518d5ada690643453eb0aef3cc7841d3623c2d, but the bug shouldn't be
