Networking In KVM
You need a traditional bridge (that acts more like a network switch).
A quick google turns up these, which might help:

Check that they’re using your static bridge. ‘virsh dumpxml‘ will have a section like:

That tells you that the interface is MAC ’52:54:00:71:20:fa’ is “plugged in” to the bridge ‘bcn_bridge1’. If that doesn’t connect to the right bridge, then you need to change it (virt-manager has a simple to use GUI
for this, or you can use ‘virsh edit
Paul,
Right, so your VMs are on the same bridge group now (at Layer2 of OSI).
Have you verified connectivity to the VMs’ default gateway?
Does the ARP (address resolution protocol) process succeed?
arp -a | grep

You may not have a NIC connected to your physical network in that bridge group. If so you need to modify your network-scripts to make that happen automatically on boot. You do not necessarily need an IP address on your bridge interface unless the VM host is acting as a router (default gateway). https://access.redhat.com/documentation/en-US/Red_Hat_Enterprise_Linux/6/html/Deployment_Guide/s2-networkscripts-interfaces_network-bridge.html
Here’s an example:
~]# cat /etc/sysconfig/network-scripts/ifcfg-XX_br0
DEVICE=XX_br0
TYPE=Bridge BOOTPROTO=static ONBOOT=yes DELAY=0
NM_CONTROLLED=no
You can temporarily add an interface to the bridge group for testing purposes though. brctl addif
http://www.tldp.org/HOWTO/BRIDGE-STP-HOWTO/set-up-the-bridge.html
An additional command to run to verify your Ethernet bridge(s) operation is:
brctl show brctl show
~]# brctl show XX_br0
bridge name bridge id STP enabled interfaces XX_br0 8000.00151713fdbc no p1p1

Hi,
You need to look at the requirements for this package. If I spin a build of that SRPM in mock I get:
Error: No Package found for aubio-devel >= 0.3.2

I have only checked the first, but aubio is neither in CentOS nor EPEL. Thus the failure.

Sorry. It’s Friday and I got distracted and answered against wrong email.
