After a replace of my mainbord and CPU I've the following problems:
VM2 can't check his license and Yum gives an IO error:
Could not retrieve mirrorlist http://mirrorlist.centos.org/?release=5&arch=x86_64&repo=os error was
[Errno 4] IOError:
Error: Cannot retrieve repository metadata (repomd.xml) for repository: base. Please verify its path and try again
When I started the server after the mainboard swap eth0 and eth1 were renemad to .bak files. And new default devices where created. I renamed them back. I think that somewhere ther is some configuration left.
Any idea where to find or set the configuration... The firewall isn't changed.
