I was wondering if ressource limitation can have negative impact on the server and cause very high load on the system.
For example with a container limited to 2 vcpu , if that container use 100% if the CPU allowed by LXD for a long period of time , the host is impacted and the load is like 30 instant of a normal 1,5 to 3 .
The host has good RAM available and lot of CPU free , but that container using 100% of its limitation seems to have negative impacts on the host.
It that true, what could be the option to ovoid such case ?
In production, if you get one of your container infected somehow and the hacker use a cryptominer that will burst CPU limits, if this impact the host and add a lof of latency to the other container, it will be a problem.
Thanks a lot for your inputs.
