After cloning a vmware image to copy to my local machine I had an issue with eth0 not coming up on an Ubuntu VM.
After a bit of googling I found a solution that required editing /etc/ftab to remove an incorrect generated mac address. Hardy Heron doesn't have this file though so I did a bit more searching around the filesystem and found a reference to the mac address stored in the vmx (vmware config) file found in /etc/udev/rules.d/70-persistent-net.rules. Note: For Debian the file can be found at /etc/udev/rules.d/z25_persistent-net.rules
Method One - delete the rules file
Quickest way to solve this is to move/delete the rules file. (Thanks to the comment from SonniesEdge.)# Ubuntu
sudo mv /etc/udev/rules.d/70-persistent-net.rules /etc/udev/rules.d/70-persistent-net.rules.old
#Debian
sudo mv /etc/udev/rules.d/z25_persistent-net.rules /etc/udev/rules.d/z25_persistent-net.rules.oldMethod Two - edit the rules file
The second way is to comment out the line relating to eth0 which had the wrong mac address and replaced "eth1" with "eth0". After rebooting eth0 should be working properly and normality will be restored.Here's an example carried out on Ubuntu.
The old /etc/udev/rules.d/70-persistent-net.rules looked like this:
# PCI device 0x1022:0x2000 (pcnet32)
SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="00:0c:29:50:xx:xx", ATTR{type}=="1", NAME="eth0"
# PCI device 0x1022:0x2000 (pcnet32)
SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="00:0c:29:36:xx:xx", ATTR{type}=="1", NAME="eth1"Was edited to look like this:
# PCI device 0x1022:0x2000 (pcnet32)
SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="00:0c:29:36:xx:xx", ATTR{type}=="1", NAME="eth0"
