First check that network manage is enabled<\/p>\n

\"\"<\/a><\/p>\n

systemctl list-unit-files | grep -i net<\/p>\n

\"\"<\/a><\/p>\n

systemctl status NetworkManager -l | grep enp<\/p>\n

My kingdom for an easy way to go back to eth0<\/p>\n

nmcli connection delete enp0s3\u00a0 \u00a0# Delete any connection from previous use of the VM<\/p>\n

\"\"<\/a><\/p>\n

nmcli connetion add connection add con-name enp0s3 type ethernet autoconnect yes ip4 10.0.2.15\/24 gw4 10.0.2.2<\/p>\n

I think nmcli is overly complex for the job it does. Since it has created a base ifcfg-enp0s3 file I prefer to edit it directly.<\/p>\n

\"\"<\/a><\/p>\n

Lets bounce networking and see what we get.<\/p>\n

systemctl restart NetworkMaanager;ip addr<\/p>\n

\"\"<\/a><\/p>\n

 <\/p>\n

Basic network tests:<\/p>\n

ping 192.168.122.1<\/p>\n

ping 10.0.2.2<\/p>\n

\"\"<\/a><\/p>\n

dig hpe.com<\/p>\n

\"\"<\/a><\/p>\n

 <\/p>\n

Next: reboot test followed by ping thy neighbor classroom.example.com.<\/p>\n

\"\"<\/a><\/p>\n

Looks like we have a winner after toggling Virtualbox an Oracle product that I hate to Internel Network.<\/p>\n

Your mileage may vary. This setup worked differently on a 2012 Mac versus this 2018 Mac versus a Dell laptop.<\/p>\n

My best environment for practice was a Dell T710 running an all Linux environment. But alas that wont fit on an airplane. I am writing this from Israel and my T710 is available in Florida via teamviewer so fans may see that environment yet.<\/p>\n
