Win XP - WIN87EM.DLL

Running latest version of unRAID OS.

Currently we are facing a issue with a virtual XP Machine.

There is a bunch of threads referring to WinFloat and Hide87, but this makes the machine insanely slow.

I've tried setting different CPU types

<cpu match='exact'>

   <model fallback='allow'>athlon</model>

   <topology sockets='1' cores='1' threads='1'/>
  </cpu>

they make XP load and shows the CPU as AMD Athlon etc.. but issue is still there.

This has been fixed for VMware, VirtualBox and Parallels

Qemu manager seem to have this fixed, but can't see how or if it's possible here.

Is there a similar fix for Unraid / KVM / Qemu ?

If i change the domain type to:
domain type=qemu

 

Then the machine starts, but goes in blue-screen with exception code 07E

Need some way of getting around the PFU / EPGFault
