Blue screen with 5.1

@wolfgang: thanks for the fast reply. So it seems that this is not the cause... well thanks again for your efforts looking into it...

please use the virtio 0.1.141 (current stable)
The 0.1.126 is know to be buggy with Win2016 and Win 10
Click to expand...

I updated virtio drivers on two Windows 10 VMs and had no crashes so far. If this is really the solution i wonder what changed in qemu. I used 0.1.126 for a long time with Windows 2016 and Windows 10 without any issues.

So far it looks good.
 
@talos: that's interesting. I'm using 0.1.141 since I opened this thread and still experience bluescreens. Can you post the output of "pnputil -e" within your VM?
 
@cybermcm
It is Host HW related. The Xeon-D as 'talos' use is not affected.
Thank to cpierr03 I can reproduce it on a E5 Hashwel CPU.
I'm have start bisecting the kernel, but i think it will take time because Windows need time to stuck.
And so it is hard to tell if the kernel work or not.
 
I found a possible bug.

Pleas try to update the microcode of your Intel CPU.
A reboot is necessary.
The procedure would work as followed.

Code: 
wget http://ftp.de.debian.org/debian/pool/non-free/i/intel-microcode/intel-microcode_3.20170707.1~deb9u1_amd64.deb
apt install iucode-tool
dpkg -i intel-microcode_3.20170707.1~deb9u1_amd64.deb
reboot

Please report back.

I did a full cleanup on the virtio drivers (uninstalled and removed old versions) and my servers ran for hours but then bluescreen again

It's really strange that this bug appears sometimes very fast after booting and sometimes hours later (without a visible cause).
@talos: is your system still stable?
 
Yep, for me the new drivers solved my problems. All VMs with updated drivers still running. I startet some other unused VMs with older VirtIO and all of them crashes after some time. I think something changed in the Hypervisor and this change is not compatible with older VirtIO drivers, which worked fine in 5.0.
 
great that it works for you. It seems that there are more or less two problems. Old drivers and some CPUs which won't work with 10/2016. I'll wait if wolfgang finds anything...

I'm currently trying to upgrade my Virtio drivers to see if that fixes the issue.

i dont know if this helps but i had similar issues with 5.0 (4.10 kernel) when i used cputype=default(kvm64)

after changing it to cputype=host... no further issues.

i didnt do kernel testing and so forth. is there any downside using cputype=host?

Host expose the whole CPU type and features to your VM. kvm64 is limited in feature flags and always show the same type to the VM. kvm64 is nice if you live migrate between hosts with different CPU types, it also helps not loosing windows activation because CPU Type, SMBIOS and stuff stays the same.
 
I already tried to set it to cputype=host, it didn't work, also bluescreen. @Lonnie: Please report back if updating virtio drivers changed something for you, didn't help me either...

understood, why choose kvm64 and not qemu64 then?
 
Same problem here, I'm running a Intel(R) Xeon(R) CPU E3-1220 v5 @ 3.00GHz with just one VM Windows Server 2012 R2. In my case, blue screen seems to just happen when system "stop" and "resume" to do the scheduled backup.

I'm changing CPU type to "host" now.

Thanks.

I am already at virtio-0.1.141. Changing the CPU type doesn't work.

I installed the old kernel (4 4.10.17-3) and until now no more blue screen.

Thanks to tall.
