Hello,
After a fresh install of libvirt in a box with one physical interface
(eth0), I tried to set up a bridged network in br0:
[ifcfg-eth0:]
DEVICE=eth0
HWADDR=48:5b:39:ba:f9:2a
NM_CONTROLLED=no
BRIDGE="br0"
ONBOOT=yes
NETMASK=255.255.255.0
IPADDR=192.168.0.10
GATEWAY=192.168.0.2
DNS2=192.168.0.6
TYPE=Ethernet
BOOTPROTO=none
DNS1=192.168.0.5
IPV6INIT=no
USERCTL=no
[ifcfg-br0]
DEVICE=br0
TYPE=Bridge
BOOTPROT="dhcp"
ONBOOT=yes
DELAY=0
NM_CONTROLLED=no
BOOTPROTO=dhcp
IPV6INIT=no
USERCTL=no
After that I get this:
br0 Link encap:Ethernet HWaddr 48:5B:39:BA:F9:2A
inet addr:192.168.0.122 Bcast:192.168.0.255 Mask:255.255.255.0

And now I don't have an IP address in eth0, but I have one br0.
Is something wrong here? I see that eth0 have "Interrupt:28", what this
mean?
Thanks in advance.
Best regards,
Lázaro.
