Hi,
I am doing xen in box gsoc project.
The aim of the project is to have custom installer ISO which delivers xen stack running on c7 along with necessary bridge networking configuration.
But I am getting confused over how to package bridge networking settings, so that I can deliver that during installation itself. I can use bridge-utils and package ifcfg-* files as differnet package. But for that I need to have the network information like how many NIC are present in the system, and which NIC is active is it eth0 or wlan0.
I can probably write a script to set up bridge networking, which can be used to start bridge networking and stop, and ship that script as a package.
Any suggestions?
Best regards, Gautam Malu
Take a look at my old notes from 2012 about this sort of thing, for CentOS 6 at https://wikis.uit.tufts.edu/confluence/display/TUSKpub/Configure+Pair+Bondin...
It will certainly need rewriting for CentOS 7 and NetworkManager, but a KVM server ideally needs pair bonding to avoid any single network piont being a single point of failure for the whole VLAN, and applying multiple VLAN's on one device or on paired devices means VLAN tagging to keep the VLAN traffic correctly segregated. While there are many upstream Red Hat published guidelines on each indivudual feature of that, NetworkManager certainly didn't encompass setting up all of them at the time: I'm curious whether it does a better job now!
