Nagios Support Forum

Hi,

I have moved nagios VM from a hyper-V to Xenserver.

All looks ok, It boots, I can login. but the network doesnt seem to be working.

I was using this:
http://exchange.nagios.org/directory/Tu ... on/details

I got to ifdown eth0
Says "Device Eth0 has mac address xxxxxxx, instead of configured address xxxxxx . ignoring

Any ideas how to overcome?

You may need to alter the network settings in centos. What are the contents of the ifcfg network config files? You may need to remove the mac address from the files. If this server has more than one nic, it may be assigning the nics in a different order under xen than it did under hyper-v.

So I assume I have to remove the hardware entry... any ideas?

I edited the file. rebooted and it seems to work.

Try removing/commenting out the HWADDR line by adding a '#' to the front of the line. Afterwards, reboot the server or restart networking.
