Host is Mac OS High Sierra VBox version is 5.2.16 Guest is Oracle Linux 7 VM Network Adaper type is Bridged
I installed and set this VM on whilst on network 172.16.21.0, and it worked fine with the VM getting a valid IP from the hosts network DHCP.
I took this Macbook to another site where they had a network with address ranges 192.168.1.0, and that too worked fine, i.e. the VM was assigned a IP address in that range from that networks DHCP server.
Today, I connect to another network at another site, with a 10.0.0.0 range, and now something very strange happens.
ifconfig enp0s3 reports no IP (4) address.
nmcli reports a IP (v4) address in the expected range.
Connectivity to/from this VM is down.
I have tried disabling/reboot/enable the device within the VM and at the VBox level, but no affect.
