Bug 1069309

Hi Ronen,

About win2008.x86_64 guest BSOD, here is the test result.

1. Tested on the following version:
   kernel-3.10.0-95.el7.x86_64
   seabios-1.7.2.2-11.el7.x86_64

1) qemu-kvm-1.5.3-2.el7  -->  fail

2) qemu-kvm-1.5.2-1.el7  -->  pass
   qemu-kvm-1.5.2-4.el7  -->  pass

Use the guest which is BSOD on qemu-kvm-1.5.3-2.el7, can boot up successfully with qemu-kvm-1.5.2-4.el7, as well do system_reset.

And I can't get qemu-kvm-1.5.3-1.el7 for it is deleted in brew, but I guess this bug was introduced from qemu-kvm-1.5.3, and I found qemu-kvm-1.5.3.1 has rebase.

2. QEMU CML:

5. And there is no load on the host, just boot up the guest using the above CML.

I have also updated bz1056982, for the info in comment 3 is win2008.x86_64 guest related. 
https://bugzilla.redhat.com/show_bug.cgi?id=1056982#c17

Here are the bugs which win2008.x86_64 guest related:
   1. Bug 1049800 - win2008.x86_64 guest BSOD (error code:0x50, PAGE_FAULT_IN_NONPAGED_AREA)
   2. Bug 1038594 - Win2008 x86_64 BSOD(0x0A) on the starting of OS
   3. Bug 1038902 - Win2008 BSOD on OS booting(0x7e and 0xc5)
   4. Bug 1049823 - win2008.x86_64 guest BSOD (error code:0x3B, SYSTEM_SERVICE_EXCEPTION) 
   5. Bug 1056982 - win2008.x86_64 guest BSOD (error code:0x19, BAD_POOL_HEADER)

I will test other guests and other bugs, and update the test result asap.
And if the info is not enough, feel free to tell me, I will add more info.

Thanks,
Cong

With the Radim and Paolo's help, found the win2008.x86_64 guest BSOD is caused by '-machine kernel_irqchip=on|off'.

From https://bugzilla.redhat.com/show_bug.cgi?id=1056982#c22:

qemu-kvm-1.5.3-1.el7  --> pass

qemu-kvm-1.5.3-2.el7  --> fail

As Radim said, this bug is caused by '-machine kernel_irqchip=on|off'.

qemu-kvm-1.5.3-2.el7:

1. -machine kernel_irqchip=on   -->  fail (BSOD)
2. -machine kernel_irqchip=off  -->  pass

CML:
/home/staf-kvm-devel/autotest-devel/client/tests/virt/qemu/qemu \
-drive id=drive_image1,if=none,cache=none,snapshot=off,aio=native,file=win2008-64-virtio.qcow2 \
-device virtio-blk-pci,id=image1,drive=drive_image1,bootindex=0,bus=pci.0,addr=05 \
-monitor stdio \
-vnc :0 \
-m 4096  \
-machine kernel_irqchip=on

Will attach the strace log later.
1. -machine kernel_irqchip=on:  quit directly when met BSOD
2. -machine kernel_irqchip=off: guest boot successfully
