I am running linux top command to see processes running inside qemu VM. Sometimes, a process does not appear in them, but if I run,

ps -eo psr,pcpu,comm | grep myprocessname

then the process is shown there. Also, such processes have low CPU utilization. Can you tell a reason of why it is so and whether it is due to the fact that processes are sleeping or something else. Thanks.

Top only displays the most cpu heavy tasks, take a look at the documentation.
