Ubuntu 16.04 Core VM VirtualBox Internal Network Problems

Question

in the file /etc/network/interfaces i changed the adapter from the usual

auto enp0s3 iface enp0s3 inet dhcp

to

auto enp0s8 iface enp0s8 inet static address 172.16.9.2 netmask 255.255.255.0 network 172.16.9.0 gateway 172.16.9.1 broadcast 172.16.9.255 dns-namedservers 8.8.8.8 8.8.4.4

so this should auto change enp0s3 to enp0s8 with the proper internal configurations for the network. instead, i get this when i ip a

2 enp0s3:<the usual broadcast multimask......> link/ether <mac that ive changed so many times now> brd ffff:ff:ff:ff:ff

ive rebooted multiple times, nothing.

added in a file called /etc/udev/rules.d/10-rename-network.rules with this one line SUBSYSTEM=="net", ACTION=="add", ATTR{address}=="<whatever ive changed the mac addr to>", NAME="enp0s8"

for my other vms, adding that file and one line worked and changed enp0s3 to enp0s8 and allowed me to talk across my internal network properly. this time it isnt. any suggestions on what i can do?

You might try some other parameters, as stated in linuxfromscratch.org.

I would use the recommended /etc/udev/rules.d/70-persistent-net.rules file name, and I would try these two additional parameters:

1. DRIVERS=="?*"
2. ATTR{type}=="1"

In my VirtualBox client (Ubuntu 16.04), adding the file /etc/udev/rules.d/70-persistent-net.rules with: SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="08:00:27:eb:4d:96", ATTR{dev_id}=="0x0", ATTR{type}=="1", NAME="enp0s8" works as expected.
