Windows 7 VM BSOD

Windows 7 VM BSOD

[Thomas Lau]

Hi All,

I am running 3.13.0-24-generic kernel on Ubuntu 14, Windows 7 VM
installation was fine, but it does random reboot by itself, the error
code is 0x00000101, does anyone know how to fix this?

Could you try hv_relaxed, like "-cpu kvm64,hv_relaxed".

Thanks,

Hi,

How do I know if my qemu-kvm version support this?

In fact I am doing testing now, but are we fixing one problem and
introduce other problem?!

I don't know which qemu version starts to support hv-relaxed,
but I'm sure qemu-1.4.1 and later versions support it.
qemu will report error if it dosen't support it.

Please show your qemu version.

Thanks,
Zhang Haoyu
hv-relaxed was started to support from commit 89314504,

I'm not sure about this, but it works on my side,
I think BSOD(error:0x00000078) has been fixed,
please show your environment.

Re: Windows 7 VM BSOD

[Thomas Lau]

"it works on your side" meaning that you had such issue but afterwards
it's all fixed by apply hv_relaxed ?

Re: Windows 7 VM BSOD

[Vadim Rozenfeld]

If you run WS2008(R2) or Win7 - always turn on relaxed timing. Otherwise
it's just a matter of time when you hit 101 BOSD.
Bugcheck 78 is quite rare one. What is your setup, and how easy it's
reproducible?
 
Best regards,
Vadim.

Re: Windows 7 VM BSOD

[tlau]

Oh I see, 

So 101 BSOD problem is well known? Can't find any document mention about 101 BSOD online. 

I tried to use hv_ other options but Win7 can't boot up properly and stucked at starting Windows screen.

The commit fc57ac2c9ca can resolve a stuck caused by hv_vapic which I encountered before.

hv_vapic provides accelerated MSR access to high usage memory mapped APIC
registers, EOI, ICR, TPR.
You can gain performance promotion from it, not too much,
but it also depends on the frequency of access to above three apic regs.

Re: Windows 7 VM BSOD

[Thomas Lau]

I see, so it's minor performance gain, and not stability related
option which is good.

I am checking http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.13.11.5-trusty/,
changelog showing lsr function is included, but when I download and
extract kvm.ko out then run nm kvm.ko | grep lsr, nothing found.

Is this the correct function?
kvm_lapic_set_eoi

I found that one tho.

It's good to have it turned on. But you definitely can drop it off.

Re: Windows 7 VM BSOD

[Thomas Lau]

since they change the logic inside a function and never change
function name, it's hard to tell by using nm kvm.ko as it only shows
what function name included on kernel module.

Yes,
if you have the source, you can directly check it.,
otherwise, decompile kvm.ko, because apic_clear_isr() is inline function,
which is called by apic_set_eoi(), you can check it, this method is a bit complicated.
Any better ideas?

Re: Windows 7 VM BSOD

Re: Windows 7 VM BSOD

[Thomas Lau]

Hi Vadim,

I want to quote back to your original post back in early 2014:
https://www.mail-archive.com/kvm@vger.kernel.org/msg99782.html


According to http://msdn.microsoft.com/en-us/library/windows/hardware/ff559069(v=vs.85).aspx
 the 0x5C means HAL_INITIALIZATION_FAILED

Problem matched exactly, which I am using CPU IvyBridge-EP and I got
same BSOD as well.

Are we missing some hyperv feature?

Some CPU flags (feature bits) should be missing.
Can you try changing cpu type?

It should be four parameters printed on the screen, right below 
the error code string. Could you please post them?

Re: Windows 7 VM BSOD

[Thomas Lau]

I briefly tested Penryn, Westmere. Bug still could reproduce.

how could I set level, model and enforce on libvirt ?! I could also
test it if you could tell me how to add those options on libvirtd.
