If you try to boot a cloned virtual machine or a physical machine, the following problems might
occur:
Š
Unable to find file systems
Š
The network is not up
Š
Change in the network device names
To fix these issues, you must disable the persistent device names for network and storage before
cloning the devices.

Disabling the Persistent Network Device Names
Review the following sections to understand how to disable the persistent network device names for
SLES 10, SLED 10, SLES 9, and NLD:

Disabling the Persistent Network Device Names for SLES 10 / SLED 10
1 Reset the udev configuration for the network devices by executing the following command:
cat < /dev/null > /etc/udev/rules.d/30-net_persistent_names.rules command
.
2 Rename the Ethernet configuration files to initialize the Ethernet devices on boot.
2a Go to
/etc/sysconfig/network
.
2b Find the
ifcfg-eth
file for each Ethernet device. In the filename, the trailing identifier
for an Ethernet device represents the MAC address for the device.
For example, in the
ifcfg-eth-id-00:AA:BB:11:22:33
file, the trailing identifier,
AA:BB:22:33
, is the MAC address for the device.
2c Rename the file to
ifcfg-ethX,
where X represents the number of Ethernet devices on
the system. For example, the name for the configuration
eth0
is
ifcfg-eth0
.
3 In
the /etc/sysconfig/network/config
file, change the value of
FORCE_PERSISTENT_NAMES
to
No
.
4 Reboot the device.
