Or my old KVM notes,for setting up the networking for TUSK software, at https://wikis.uit.tufts.edu/confluence/display/TUSKpub/Install+KVM+Hyperviso.... Libvirt, NetworkManager, and the system-config-network tools of RHEL and thus of CentOS have no configuration tools that handle pair bonding, and the published directions for pair bonding and bridging needed.... a lot of work, which is why I wrote those.

I upgraded from CentOS 5.9 to CentOS 6.4.
I try to reuse my virtual machines and am only partially successful: I
can run them, I just cannot get the network OK and need
some help with that.
What I had in the past was pretty simple: both the host and the VM’s
used eth0 and each had an IP in the same subnet and could
communicate freely. With the new install it seems somewhat more complex
and I think I need to configure a bridge and use that.
Unfortunately, info I find through google is overwhelming and confusing.
All examples either configure something else, or the
outcome is not what expected.
So: how to go about setting things up to have say:
My physical machine is on 192.168.0.90
My Virtual machines are on 192.168.0.100 and 101.
These are to be fixed addresses.
The 2 VM’s have to communicate with each other and with the physical
machine.
The VM’s do not necessarily need to communicate with the rest of the
world.
The physical machine needs to communicate with the rest of the world.
I use:
CentOS-6.4_64
Virtual Machine Manager 0.9.0
xen 4.2.3
libvirt 0.10.2.7-5
VM’s show Hypervisor = xen (fullvirt)
Emulator = qemu-dm
NIC points to Shared device name virbr0
on the host, virbr0 has IQ 192.168.122.1
I have been fighting this for 2 weeks, now. I tried to follow several
advises which resulted in either the VM’s not connecting
to anything, or my host losing its connection to the rest of the world,
or both. So either I still do something not-right, or I
follow the wrong gidelines.
Can someone give me a push in the right direction, please?
