RHEL, failed to add iptables rule to allow DHCP requests from 'virbr0'
I've just updated my RHEL 5.3 box with the last months' updates moving it to the 5.4 release.
Just after the yum update finished I've begun to receive a LOT of messages containingOBJECT: python /usr/share/rhn/virtualization/poller.py BODY: libvir: QEMU error : failed to add iptables rule to allow DHCP requests from 'virbr0' : Invalid argument
The solution to that, after a yum whatprovides "*/poller.py" was to remove any instance of the rhn-virtualization-host from my machine (since I do not have any virtualization need).

in Command Line defence
With this close connection, learning about the command line makes more sense in GNU/Linux than in many operating systems. You do not need to be full of command line macho, believing that the only real computing goes on at a command prompt, to appreciate the connection. While the command line is in many ways the opposite of the desktop, in that it is thorough and encourages the gaining of expertise, the two interfaces are complementary. For simple, routine tasks, the desktop is often preferable, especially if you are viewing graphics. If you want to administer your system or fine-tune performance, then the command line is the interface you need.
