URSim with realtime Linux kernel fails in thread scheduling

Hello All,

I am using a Ubuntu 20.04 VM with real-time kernel linux-5.11.4-rt installed on it. While launching the ROS node, I am getting the following errors with the URSIm simulation.

“Unsuccessful in setting produce thread realtime priority. Error code: 1”
“Producer thread: Scheduling is NOT SCHED_FIFO!”

Can anyone please help me with this issue?
