WMWare Workstation, error eth0 despues de clonar una MV

He estado desarrollando un proyecto en el cual tengo que virtualizar una red utilizando WMWare Workstation. Sucede que cloné una VM Ubuntu 7.10 Server y al momento de querer ver la conectividad de esta nueva VM clonada, me vi con la sorpresa de que tal conexión no se daba.

Luego de intentar una y otra vez con

#sudo /etc/init.d/networking restart

y con

# sudo dhclient eth0

me arrojaba un error de que el dispositivo (eth0) no existía. Y efectivamente sucedía esto.

Al ejecutar el comando # sudo ifconfig -a para ver todos los dispositivos o adaptadores que tenía la VM no me reconoce la eth0 pero si la eth1.

El inconveniente surge por un problema de direccionamiento en el archivo: /etc/udev/rules.d/70-persistent-net.rules, archivo en el cual se hace referencia a una dirección mac incorrecta para el adaptador eth0.

La solución es editar tal archivo de modo que la configuración quede de la siguiente manera:

#sudo nano /etc/udev/rules.d/70-persistent-net.rules:

# PCI device 0x1022:0x2000 (pcnet32)
SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="aa:bb:cc:dd:ee:ff", ATTR{type}=="1", KERNEL=="eth*", NAME="eth0"
# PCI device 0x1022:0x2000 (pcnet32)
SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="gg:hh:ii:jj:kk:ll", ATTR{type}=="1", KERNEL=="eth*", NAME="eth1"

Aquí se podría eliminar las dos primeras líneas o bien comentar la segunda línea y en la última línea cambiar el “eth1” por “eth0”

more /etc/udev/rules.d/70-persistent-net.rules
# PCI device 0x1022:0x2000 (pcnet32)
SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="gg:hh:ii:jj:kk:ll", ATTR{type}=="1", KERNEL=="eth*", NAME="eth0"

Asunto arreglado.
