You need to add eth0 to the bridge (br0) which you already did. But do
NOT assign an IP address to eth0. Instead, assign the host's IP to br0.
Then just use another of your IPs for your VM (which can also be called
eth0 inside your VM).
This way your host and your VM(s) can communicate with each other via
the bridge.
Note: If you want to use more than one IP address to access your host,
then create alias interfaces on the host for the bridge such as br0:0,
br0:1, etc.
Do not create alias interfaces on eth0. Also do not create an alias
interface on your host for the IP(s) which you'll be using inside your
VM(s).
I hope this helps.

Hi,
I have the following issue i recently installed a VM with qemu and
libvirtd, everything is almost ok. The problem is that i have 5 usable
IP address (valid ip address on internet) for eth0, and i want to use
one of this IP for my VM (Windows 2008 Standard R2 by the way). I did
the bridge between my eth0 and br0, the VM could browse into internet
and download patches, etc. etc.
I tried to use a networking alias, this is the network interface eth0
assign a IP address and for the eth0:1 assign other IP address, and
this bridged to the br0 instead of eth0 to eth0:1; after restart the
network service the connectivity lost, and then get in back the
original configuration everything seems to work again. But my goal is
not archived.
Goal:
eth0 must have a valid ip address to be accesed, eth0:1 (bridged to
br0) must have a valid address to be assigned to the VM. Through
iptables assign ACL to each IP address (valid IP address) depending of
the services to host (web server and db server, rdp host) and between
interfaces could be possible to communicate between them (virtual host
and virtual machine).
eth0: Virtual Host
eth0:1: Virtual machine (bridged to br0)
Thank you very much for you time.
Best regards,
RR
