Hello!

I did check logs from hosts, but didnt notice anything that would help me. I can copy paste logs later.

I was not trying to get qemu crash vm. 
I'm trying to add new functionalities with qemu. 

I wasnt sure if my syntax was correct, so I copy pasted the example command for spice from that website. And it still behaves similarly. 

My conclusion is that qemu cmdline is setup wrong or it's not working at all. But I dont know how to check that.

If you intended, with the params you passed, to make qemu fail, for whatever
reason (debugging qemu?), then it's not a bug :-) Otherwise, it is, but we
can't know where.

Did you check relevant logs? vdsm/libvirt?
