*** Error: Cannot start BESS daemon

[oranichu]

Hey all, I'm trying to familiarize myself with BESS and whilst following the installation guide I've run into some issues.

Firstly I'm running on a VM running Ubuntu 18.04.5 LTS (GNU/Linux 4.15.0-135-generic x86_64) as root while running this

git clone https://github.com/NetSys/bess.git
cd bess/env
vagrant up

The command vagrant up failed and by reading a bit on forums I got the impression it won't work because I'm running this on a VM, by running sudo kvm-ok i'm getting :

INFO: Your CPU does not support KVM extensions
KVM acceleration can NOT be used

Yet I tried the other option in the guide and run the ./build.py file after installing all the dependencies and afterwards typing daemon start this is the error i'm getting :

Connection to localhost:10514 failed
Perhaps bessd daemon is not running locally? Try "daemon start".
<disconnected> $ daemon start
E0510 18:29:48.205183 2509361 bessd.cc:356] Failed to launch a daemon process
*** Error: Cannot start BESS daemon

By looking at the log files :

seems like the error is (Cannot allocate memory), maybe i'm uncapable of running BESS on my VM ? or I havn't configuerd something properly ? any suggestion might help.

Thanks for the help :)

Did you allocate hugepages on your system? If you instead want to use regular memory append -m 0 to bessd commandline.

Seems like it's working, Thanks !!
