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.<br>
Then just use another of your IPs for your VM (which can also be
called eth0 inside your VM).<br>
This way your host and your VM(s) can communicate with each other
via the bridge.<br>
<br>
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.<br>
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).<br>
<br>
I hope this helps.<br>

<p class="MsoNormal"><span lang="EN-US">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. <o:p></o:p></span></p>

<p class="MsoNormal"><span lang="EN-US">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.<o:p></o:p></span></p>

<p class="MsoNormal"><span lang="EN-US">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).<o:p></o:p></span></p>
