osboxes VM:-(CentOS7) - Cannot find a valid baseurl for repo: base/7/x86_64

 I have observed this error on CentOS7 VM.  I have tried a couple of things and finally, I have fixed them with the below steps. 

FYI,

#yum update //i got below error

Then I will execute the below commands,

[root@osboxes]# ONBOOT=no

[root@osboxes]# dhclient

[root@osboxes]# yum update

I hope it will help you.
