Hello looks like your stress test " single thread CPU" is running 1/28 100% vcpu so on host it cannot be more than qemu other stuff and added vmachines cpu usage.If you wanna make a stress test that impact the host CPU load with many-vcpu machines you must use a multithreaded stress test. This is just a reading/wanted result problem not a technical one (If I understand well your needs).

We tested it on centos7.2. Do you have any solution ?thanks. Cordialement Francois Pussault 10 chemin de négo saoumos apt 202 - bat 2 31300 Toulouse +33 6 17 230 820 fpussa...@contactoffice.fr
