Hello. I desire to get bridge network working using virt-manager. Centos 7 and centos 7 guest.
From researching I think I need to have a ifcfg-br0 file like this ?
cat ifcfg-br0 DEVICE=nm-bridge0 STP=no TYPE=Bridge BOOTPROTO=none IPADDR=192.168.1.8 PREFIX=32 GATEWAY=192.168.1.1 IPV6INIT=no NAME=br0 ONBOOT=yes DELAY=0
Is that for sure needed ? The use that nm-bridge0 as the network name?
I dont want to mess up my current setup. Thanks,
Jerry
Use the virt-manager to create the desired bridge. It will end under /etc/libvirt/qemu/networks/. And there probably exists already a
# cat /etc/libvirt/qemu/networks/default.xml <!-- WARNING: THIS IS AN AUTO-GENERATED FILE. CHANGES TO IT ARE LIKELY TO BE OVERWRITTEN AND LOST. Changes to this xml configuration should be made using: virsh net-edit default or other application using the libvirt API. -->
