Description Richard W.M. Jones 2013-09-25 12:00:19 UTC 
Description of problem:

We need to backport the following patch to libguestfs in RHEL 7.0:
https://github.com/libguestfs/libguestfs/commit/2f4f7726e8c81cc56befcb7caa78c01174354d76

The reason is that libvirt <cpu mode="host-model"> doesn't work
on some CPUs (bug 870071) and they are no closer to fixing
that.  So we work around that bug using host-passthrough which
just passes -cpu host to qemu.

Version-Release number of selected component (if applicable):

libguestfs-1.22.6-8.el7

How reproducible:

100%, on some hardware

Steps to Reproduce:

Unfortunately this bug is only reproducible on certain Intel
Sandybridge hardware, not in general.  On hardware where
libvirt demonstrates this bug, you can just do:

LIBGUESTFS_BACKEND=libvirt guestfish -a /dev/null run : available btrfs -v

and you will see the guest kernel crash with a backtrace
that includes 'xor_avx_2'.  If your hardware doesn't
demonstrate the bug, then the command above will succeed.

It's known to fail on this processor:
Intel(R) Core(TM) i7-2600K CPU @ 3.40GHz
(see https://bugzilla.redhat.com/show_bug.cgi?id=870071#c8 )
Comment 1 Richard W.M. Jones 2013-09-26 12:14:02 UTC 
The fix is included in libguestfs-1.22.6-9.el7 but I cannot
add this bug to the erratum without getting qa-ack.
Comment 2 Can Zhang 2013-10-10 06:59:49 UTC 
I'm kind of confused about how to reproduce this bug.

Here's what I have tried:
1. Install a rhel7 guest in KVM, using config file

  <cpu mode='host-model'>
    <model fallback='forbid'/>
  </cpu>
2. Install libguestfs-1.22.6-8.el7 in the guest
3. Run `LIBGUESTFS_BACKEND=libvirt guestfish -a /dev/null run : available btrfs -v` in the guest as you mentioned. And it runs smoothly.

modprobe btrfs
[    6.562521] xor: measuring software checksum speed
[    6.572567]    prefetch64-sse:  1124.000 MB/sec

[    6.791266] bio: create slab <bio-1> at 1
[    6.801237] Btrfs loaded

I also tried run that command directly on host, and it also worked.
And the host CPU is i7-2600, the nearest model I could find.

Could you clarify the procedure a bit?

This is wrong.

Install libguestfs *in the RHEL 7 host* and just run this command
*in the host*:

LIBGUESTFS_BACKEND=libvirt guestfish -a /dev/null run : available btrfs -v

There is no need to install a guest.
Comment 4 Richard W.M. Jones 2013-10-10 07:56:42 UTC 
The host is running RHEL 7 too?

Also please include the complete output of the command when
run in the host.

The host is running fedora 21 rawhide, and a complete output is:

I believe the version is correct:

Comment 6 Richard W.M. Jones 2013-10-10 09:06:10 UTC 
Rawhide but with the RHEL 7 libguestfs package installed?

Anyway, this hardware isn't hitting bug 870071.  Only certain
hardware does, and I don't know exactly what hardware, except
that I own 1 machine which demonstrates it.  You could maybe
compare your /proc/cpuinfo output with the data in bug 870071.

Yes, I downloaded the packages from brew.

I compared the CPU flags and found some subtle differences:

i7-2600 has: eagerfpu smx
i7-2600K has: x2apic
Comment 8 Richard W.M. Jones 2013-10-10 10:19:28 UTC 
You really need to look at what -cpu flag is being
passed to qemu.  cf:
https://bugzilla.redhat.com/show_bug.cgi?id=870071#c5

Understand your situation now. I create a vm using <cpu mode="host-model"/> and find the `-cpu` flags passed to qemu is:

-cpu SandyBridge,+osxsave,+pcid,+pdcm,+xtpr,+tm2,+est,+smx,+vmx,+ds_cpl,+monitor,+dtes64,+pbe,+tm,+ht,+ss,+acpi,+ds,+vme

libvirt detects "SandyBridge" correctly, your problem cannot be reproduced on my machine. I think I might try to find some other hardware.

I cannot find a i7-2600k machine here in Beaker, could you help find a machine I could use for testing?
Comment 11 Richard W.M. Jones 2013-10-14 07:54:23 UTC 
The only machine I know about which demonstrates this bug
is my own development server, which you can't use.  If you
can't find one in beaker, then I can't help further.  It's
possible we simply cannot reproduce this bug with available
resources.
Comment 12 Wei Shi 2013-10-25 02:56:47 UTC 
Hi Rich,
  Would you like to help us to verify this bug with your development server? QE will do Acceptance Test for libguestfs package.
Comment 13 Richard W.M. Jones 2013-10-25 08:45:03 UTC 
Nope, it's remote and running my build system so I simply can't put
RHEL on it.  You'll just have to accept this bug cannot be verified
unless there happens to be a system in Beaker (which it seems we
can't find).
