The screenshot when guest hang

The screenshot when guest hang.

Found the problem happens in kernel-120 sometimes too. But its reproducibility is very lower than 121.
In kernel 148, I have not met this problem.

Hit same issue when install windows7-64 guest on AMD host.
How reproducible:

hangs in shutting down

This request was evaluated by Red Hat Product Management for inclusion
in a Red Hat Enterprise Linux maintenance release. Product Management has 
requested further review of this request by Red Hat Engineering, for potential
inclusion in a Red Hat Enterprise Linux Update release for currently deployed 
products. This request is not yet committed for inclusion in an Update release.

Re-test with kernel-2.6.32-125.el6.x86_64, use the same command line in bug description and boot win7-32.qcow2 guest. The problem still can be reproduce sometimes.

Does it works over Intel host?

> Does it works over Intel host?

I found this issue on Intel host.
According to Comment 5, this issue happens on 
AMD host as well.

Hi, Dor
This bug will block the upcoming SVVP test for submission.
We are running svvp regression test with kernel-120 now. 
Could you guys help to have a look at this bug?

Thanks

It is also a testblocker for testing windows installation from WDS Server.

Marcelo, can you produce a private brew build to let QE verify that the fix works early enough?

Hi, Marcelo
Verified with the build you provided with win2k8 and win7 images.
Reboot 5 times for each guest and they can restart smoothly.
So this issue is fixed in that build.

Thanks

Hello Redhat,

I feel , the Bug 684719 - Windows guests hang when rebooting with kernel-2.6.32-121.el6, is a different issue as compared to this bug. In this bug, Windows2008 32-bit guest installation isn't proceeding at all with smp > 1.
Installation happens fine when we assign cpu =1.

Thanks,
Santwana

This was tested with 20110413.1 build for SNAP4 and it still fails.

Hi,
Seems the fix is not included in SNAP4. Please have a check after SNAP5 comes out.

Thanks.

Patch(es) available on kernel-2.6.32-131.0.2.el6

Re-test with kernel-2.6.32-131.0.2.el6, this issue does NOT exist.
But according to Comment 29, the patches were reverted in 131.0.3.el6.
So tried with kernel-2.6.32-131.0.5.el6, the problem happens again. Guest hangs during reboot.

I can reproduce when install win7.64 in Intel Q9550

Suqin,

This appears to be a different bug. I suppose the guest is hung at the point you attached gdb to qemu-kvm process? 

Please reproduce and gather the following information:

- Screen capture
- In the QEMU monitor:

info registers
cpu_set 1
info registers
cpu_set 2
info registers
cpu_set 3
info registers

- Is it reproducible with other guests?

Also, is win2k8 also affected?

btw: Please refrain of testing the -cpu model+flags.
Just stick to the supported models w/o changing the flags

In case it is another bug, open a new one and verify this one

And reproduce without qxl please.

1. repeat winxp, win2008, win2008r2, win7, win2003 installation (ide/rtl8139/spice) on the same host (Intel Q9550) can not reproduce.

2. It needs around 40 mins to reboot guest while I install win7 on host 4450B

3. will verify this bug, and open new bug to trace 2. issue

create bug 699991 to trace issue in comment 36

Hello Suqin/Red Hat ,
(In reply to comment #25)

I got confused. Comment from Suqin (comment #41) says verification is passed. But he has not mentioned which version of the kernel he used. Can you tell me which version has fix to this bug ?

Vasant

hello ,Vasant

In kernel-2.6.32-131.0.2.el6 the patch included ,and reverted in kernel-2.6.32-131.0.3.el6
The patches were included again on kernel-2.6.32-131.0.7.el6.

Hello Redhat,

This issue is still reproducible in the build 20110427.0( k.v- 2.6.32-131.0.10.el6.x86_64). When installing a Windows2008-32 bit guest with > 1 vcpu, installation fails. Installation happens fine, if we allocate 1 vcpu.

The ISO is copied on the host server for installation.

The host model is: x3650, Intel Xenon Quad core 3.00GHz, with 16GB memory.

The windows version used is: Windows Server 2008 Datacenter, Enterprise, and Standard with Service Pack 2 Debug/Checked Build (x86) - DVD (English)  version.

ISO: en_windows_server_2008_datacenter_enterprise_standard_sp2_checked_build_x86_dvd_342434.iso.

Thanks,
Santwana

There will be a significant impact if this is not fixed.

1) KVM test will not be able to exit test without an exception since we are required to run 100% of our test. This bug is currently blocking 4% of our tests.

2) Windows 2008 32 bit guest becomes unusable on RHEL6.1. This would be a significant regression from RHEL6.0 for customers.

Hi Red Hat, You marked RHBZ684719  as Verified and spun off a new RHBZ699991 to cover a separate defect. We tested an early RC and even the part of this problem covered in RHBZ684719 is still failing. This issue is blocking test but more important is a key issue that customers will expect fixed as early as possible i.e. 6.1 or 6.1 day-0 or 6.1.z. Many thanks.

Hello Redhat,

I tried installing the Windows2008-32 bit guest using a *non-checked build* [en_windows_server_2008_datacenter_enterprise_standard_sp2_x86_dvd_342333.iso]  on the 20110427 build and the installation is passing even if we assign vcpus > 1.

Please note in my previous comment, I was using "Windows Server 2008 Datacenter, Enterprise, and Standard with Service Pack 2 Debug/Checked Build". The issue is still there with the Debug/Checked Build, installation fails allocating more than 1 vcpu.

Thanks,
Santwana

Lowering the priority to high, as we can install the *non-checked* build version of the Windows2008-32 bit.

Hi, IBM

I think the problem of win2008-32 big guest installation failed with more than 1 vcpu when using a Debug build is a different issue with this one(windows hang during reboot), so can you please report a new bug? thanks.

BTW, In our test, we always use the "non-checked" build : en_windows_server_2008_datacenter_enterprise_standard_sp2_x86_dvd_342333.iso

------- Comment From ryanh.com 2011-05-03 10:03 EDT-------
This IBM bug has always been about install failures on >1 SMP with win2k8 , turns out  it only fails with the debug builds.  At some point, Dor marked this as duplicate of

bug 684719

but, it isn't.
