pyvisa in linux seems not working

[choudad]

Hi guys just in case anyone of you tried control equipment in virtual machine before may help me

I got Win10 as host and Centos7 as guest in VMware,  in host Win10 pyvisa talk to equipment very well, everything is working.

But in guest Centos pyvisa seems not able to retrieve any ethernet connected equipment.

pinging to equipment ip address from guest OS  shows connected:

(base) [aaronfan@localhost ~]$ ping 10.0.22.30

PING 10.0.22.30 (10.0.22.30) 56(84) bytes of data.

From guest Centos pyvisa-info I don’t see anything wrong either, Guest OS pyvisa-info:
