I have created a perfect ready install of Ubuntu 14.04 (newest build) and it works just fine on the system it was installed on.
I have cloned that drive and wish to use it on other servers. However when I am using it for the next machine I have no Ethernet cards.
When I type: ifup eth0 or ifup eth1 I get the reply:
Cannot find device "ethx" Error getting hardware address for "ethx": No such device
I have tried removing: /etc/udev/rules.d/70-persi
I have tried checking the mac address of a card with lspci -v and inserted a visible mac into 70-persistent-net.rules but still nothing
Clearly when Ubuntu installs initially, it figures out the right Ethernet driver to get things going. How can I reinitialize that process without reinstalling Ubuntu again.
I have two ethernet cards and it's not loading the correct driver for either one.
Screenshots attached of
lspci -v on two ethernet cards
results of ifconfig -a
contents of /etc/network/interfaces
Strangely, ifconfig -a shows strange entries of em1 and p3p1 instead of ethx.
The virbr0 returned in ifconfig -a is expected due to virtual machine needs
What sayeth the group ?
