At this point it's not about writing code but to debug and understand the 
problem first which takes testing, experimenting and investigating it that 
anybody can do who can run it and willing to search for info and try to 
get to the bottom of the problem. If you can _read_ C code that's enough, 
no need to write it. (OK understanding QEMU is complex but you can always 
ask here if you have a specific question.) Once the problem is understood 
somebody will be able to come up with a patch you could test but that 
won't happen until you get the logs and info necessary to understand the 
problem. So you should read on how to enable KVM tracing in the kernel, 
how it works in general, etc. similar to the links I've sent and try to 
find what's happening when you run it. The actual problem may be before 
you get the error so it's more about debugging and investigating than 
coding so don't let that hold you back.

Hope it inspires you or somebody else interested in it to at least try to 
understand the problem better which may be all that's needed for somebody 
to make a fix eventually. So you need to help with the hard part of 
debugging it then those who know QEMU and the kernel can write the code 
needed but they can't do the debugging because they don't have the 
hardware, interest and time to do that so those who have these need 
contribute it.
