So my situation is, I was previously able to setup network connectivity on my RHEL-7 guest OS (running on host OS Windows 7 using VirtualBox). I messed up an upgrade causing a kernel panic, so I reverted to my current kernel, but now it seems I have lost my network connectivity. Removing the new kernel did not help. Every now and then I would get the balloon message that says "Activation of network connection failed."
Not sure what information I should provide, so I refer to RHEL 7.0 can't connect to internet:
ifconfig enp0s3 output:

Please let me know if I need to provide more info, thank you.
