CPU issue while trying to run gnb on a ubuntu virtual machine

[AmatipIT]

Can anyone help with possible solution to this error

VirtualBox:~/srsLTE/build$ gnb
srsLog error - Unable to create log file "/tmp/gnb.log": Permission denied
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)

Aborted (core dumped)
ola@ola-VirtualBox:~/srsLTE/build$

please run as:

sudo ./gnb -c ./gnb.yaml

Please note that a virtual CPU does not support the required CPU features. Please build the project again with correct cmake config.

Please can you direct me to the correct cmake config to make this work?

The default cmake file is here. It should automatically detect the available ISA:
