Great stuff, but I’m wondering how can I put this stress test on my ESXi host without creating any new VM.

When I try to GPU burn test there are errors showing the:
gpu_burn-drv.cpp:in function int main(int, char**) gpu_burn-drv.cpp:816:23: error: runtime_error is not a member of std throw std: : runtime_error("No cuda capable gpu found.\n)
But when I install ubuntu on the same server GPU burn test is ok so I can’t understand what is the issue so anyone tells me what to do……

I am using this stress-ng image and applying chaos at K8's level as I am building chaos as a service. I am planning to put CPU stress. I was expecting the CPU % to spike > 80%. My hypothesis is similar to your uptime values ~ 1- 2% and when I apply CPU stress it is hardly spiking up to 10%. I tried various params but this is the max spike I get. Can we ever make CPU stress > 80% ? as I see even your load averages pretty low.

Many thanks for the correction, we will cross check this.

--vm-bytes is NOT per vm worker but for all workers combined, so you can put almost all your memory if you boot without X.
