8 months ago Hi @LingeshWaran, we dont recommend to install srsRAN Project in a VM. Due to the real-time requirements of the DU using a VM is usually not straight forward. You need to use a VM that supports real-time applications like ESXi from VMWare [1] and you need to know exactly what you are doing. Is it possible to use a docker in your setup?
Regarding the srsran_performance script: Inside a VM you cannot influence the performance governor of the host system, because the VM doesnt have the rights to modify these parameters.

while installing srsRAN_Project in my laptop with Oracle virtual box running ubuntu with 4 cores and 4GB RAM:
Issue Description
srsran_performance throws an exception & Unable to start gNB
Setup Details
Dear Sir/Madam, Warm greetings. I am serving as an assistant professor in the dept. of ECE, St. Joseph's College of Engineering,OMR, Chennai, India. I am planning to set up a basic 5G E2E testbed using COTS UE, NI USRP B210, srsRAN_Project and Open5GS Core. I started with srsUE and ZeroMQ libraries to emulate the RF environment. I encountered the following error while installing srsRAN_Project in my laptop with Oracle virtual box running ubuntu with 4 cores and 4GB RAM:
root@5GTIC:/srsRAN_Project# sudo scripts/srsran_performance Would you like to set the CPU governor to performance: [Y/n]: Y *tee: '/sys/devices/system/cpu/cpu/cpufreq/scaling_governor': No such file or directory**
I continued to complete the installation of Zero MQ libraries, srsRAN4G and Open5GS. I was able to start my Core but gNB terminal showed the following exception:
root@5GTIC:/srsRAN_Project/build/apps/gnb# sudo gnb -c /home/lingesh/Downloads/gnb_zmq.yaml The PRACH detector will not meet the performance requirements with the configuration {Format 0, ZCZ 0, SCS 1.25kHz, Rx ports 1}. srsGNB ERROR: The CPU does not support the required CPU features that were configured during compile time: sse4.1(ok) avx(ok) avx2(ok) fma(na) pclmul(ok)
I am able to start UE too. Please help me in this regard. Kindly find the attached snapshots.
Expected Behavior
CPU performance should be tuned and gNB should start
Actual Behaviour
