Hi,
As the next email in the thread mentions, worth trying different CPU family 
(make sure you dont’ use anything too old due like Conroe), or host CPU 
passthrough.
I would certainly suggest to try the qemu-kvm-rhev/ev since it focuses on 
stability. Try RHEL/CentOS host instead of Fedora. 

Thanks,
michal

In my case I could solve this issue by changing the number of (virtual)
CPUs to only 1 for the Windows 10 VM. The Windows 10 VM is running
pretty stable for several months now.

IIRC this is related to the Host CPU or Cluster CPU Type.

Hi Michal, 

I did try a clean install.  Both an upgrade and a fresh install cause a blue 
screen.How do I pin point the blue screen?  I’m guessing it’s a QEMU issue 
with Win 10.  I’m on Fed 22, how do I get a newer QEMU than what’s in the 
distribution?  or should I just upgrade to Fedora 24?

I would expect better luck with virtio drivers. Either way, if it was working 
before and not working in Win10 it’s likely related to drivers. Can you make 
sure you try latest drivers? Can you pinpoint the blue screen…to perhaps USB or 
other subsystem?
Might be worth trying on clean Win10 install just to rule out upgrade issues (I 
didn’t understand whether you cloned the old VM and just reinstalled blue iris 
or reinstalled everything) , and if it still reproduces it is likely some low 
level incompatibility in QEMU/KVM. You would likely have to try experiment with 
qemu cmdline or use latest qemu and check the qemu mailing list
