[Коренберг Марк]

When booting another kernel (like RHEL 6.0) in guest, kernel hang on the line:
Probing EDD (edd=off to disable)... ok
Really, it hang  in set_64bit inside function native_set_pmd()

[Froggy]

Change proposal for Maverick (2.6.35) based on kernel patch in description:
   * kvm_emulate.h:
      * Change struct operand so that val and orig_val will be changed from unsigned long to union like this:
            union {
                  unsigned long val;
                  u64 val64;
            }

   * emulate.c:
      * in emulate_grp9() change all occurences of c->dst.val to c->dst.val64.
      * In x86_emulate_insn() change line "c->src.orig_val = c->src.val" to "c->src.orig_val64 = c->src.val64".

The MeeGo qemu will start work then.

Please test the package at

If that kernel works, I'll complete the SRU process to request the
maverick kernel get this patch.

Copied from #11271 and #11378

Some findings of the QEMU-KVM issue on Ubuntu 10.10.

The QEMU-KVM hung during booting up meego-netbook kernel. The netbook kernel is
2.6.35 with some Intel patches. I did below test:

QEMU:
1, qemugl in MeeGo 1.1 SDK, which version is 0.12.4
2, qemu installed from Ubuntu 10.10 repo, which version is 0.12.5

Kernel:
a, handset netbook kernel in MeeGo 1.1 release, major version is 2.6.35
b, Ubuntu 10.10 kernel, major version is 2.6.35

                    Result       
1 to boot a         FAIL
1 to boot b         SUCCESS
2 to boot a         FAIL
2 to boot b         SUCCESS

So the problem is quite like that MeeGo kernel has something special which
cannot work well with the KVM in Ubuntu 10.10 host kernel.

Update some more investigation result.

The KVM (in 2.6.35.23 linux kernel on Ubuntu 10.10) seems to hang in
__vcpu_run() in arch/x86/kvm/x86.c. When the client OS is running above
instruction, KVM goes into dead loop in __vcpu_run(), because the
"vcpu_enter_guest ()" always returns "1".

The scenario seems to be as follow: The instruction triggered page fault
to exit kvm guest, and then "kvm_mmu_page_fault" was called to handle
the exception. The function returns non-zero value to let instruction be
run again, and suppose that the page fault has been resolved. But for
some reason, the page-fault exception was still triggered, and code run
infinitely in the loop.

Update some findings through GooGle:

1, Similar KVM hanging issues were reported, like:
https://bugs.launchpad.net/ubuntu/+source/qemu/+bug/688085

According to the fix from Avi Kivity, it looks like a bug in KVM
handling 64-bit operand of "cmpxchg8b". But it is interesting that KVM
on Ubuntu 10.04 and ubuntu 9.10 did not encounter the hanging issue
running the 2.6.35 guest kernel.

http://www.spinics.net/lists/kvm/msg40800.html

Will try the kernel built from latest git tree to see whether the
problem could be resolved.

2, Below one seems to be discussing the similar problem but for
different root cause. Just a note here. The patched mentioned in below

Patch is said to be in maverick-next.

I'd like to hear confirmation (or denial) from original bug reporter as
to whether the patch fixed the problem.  (I'm unconvinced that this is
actually a dup of the Meego bug)

[Zhiyuan-lv]

Ubuntu 10.10 will update kernel to contain a back ported kvm fix, which
probably in the next version after 2.6.35.24. Meanwhile, it is possible
to manually build newer version of kvm to have the problem fixed.

The tar ball of kvm source code could be downloaded from below:

http://sourceforge.net/projects/kvm/files/kvm-kmod/2.6.37/

I tried the package on my Ubuntu 10.10 (kernel 2.6.35.23) T61 laptop
with Intel Core 2 due 32-bit CPU. Using the new kvm, I could boot up
meego kernel successfully. Hope that could help. Thanks!

Hi Zhiyuan-lv,

the fix is currently in maverick-proposed.  You can use that kernel by
adding something like

deb http://archive.ubuntu.com/ubuntu/ maverick-proposed main

to your /etc/apt/sources.list.

I don't know how long it will take for this fix to move from maverick-
proposed into maverick.  Perhaps someone on the kernel team has an idea?

Bug description:
  Binary package hint: qemu

  Guest kernel hang during boot when KVM is active on i386 host

  See the patch.
  http://www.spinics.net/lists/kvm/msg40800.html

  How to reproduce:
  1. install Maversick x86 (not amd64)
  2. ensure you have  kvm support in processor
  3. kvm -kernel /boot/initrd.img-2.6.35-24-generic-pae
  4. kvm -no-kvm -kernel /boot/initrd.img-2.6.35-24-generic-pae works OK.

  SRU Justification:
  Impact: Users cannot boot KVM guests on i386 hosts
  2. How bug addressed:  The upstream commit at http://www.spinics.net/lists/kvm/msg40800.html fixed it
  3. Patch:  A kernel patch is attached to this bug.
  4. Reproduce: boot an i386 kernel on a kvm-capable host.  Try to boot a kvm guest.
  5. Regression potential: since this is cherrypicking a commit from a future upstream which had already been changed, regression is possible.  However if there is a regression, it should only affect users of KVM on i386 hosts, which currently fail anyway.
