That test case fails on my system (Fedora 29 x86_64). Avocado seems 
unable to kill the VM so it  reaches the timeout.

I compiled QEMU with default configuration:

$ configure --python=/usr/bin/python3 --target-list=x86_64-softmmu 
--target-list=x86_64-softmmu,mips-softmmu,mips64el-softmmu,ppc64-softmmu,aarch64-softmmu)

Follows a snippet of the Avocado's job.log file:
