Get Ethernetcard working again in Linux under ESXi

After installing Ubuntu Server on Vmware ESXi, I couldn’t find a NIC:

sudo /etc/init.d/networking restart

Reconfiguring network interfaces…

eth0: ERROR while getting interface flags: No such device  
SIOCSIFADDR: No such device  
eth0: ERROR while getting interface flags: No such device  
SIOCSIFNETMASK: No such device  
SIOCSIFBRDADDR: No such device  
eth0: ERROR while getting interface flags: No such device  
eth0: ERROR while getting interface flags: No such device  
Failed to bring up eth0.

Problem is that the ethernet MAC addresses are cached.

To remove the cache values:

sudo rm /etc/udev/rules.d/70-persistent-net.rules

Reboot, and it should work.

Other NIC files:

/etc/hosts - change ip address and hostnames
/etc/hostname - change hostname
/etc/network/interfaces - change ip address
