Hi, I am confused regarding KVM networking. I have configured base OS and guest OS. [root@baremetalinhousebaseserver1 network-scripts]# cat ifcfg-br0 TYPE=bridge PROXY_METHOD=none BROWSER_ONLY=no BOOTPROTO=static DEFROUTE=yes IPV4_FAILURE_FATAL=no #IPV6INIT=yes #IPV6_AUTOCONF=yes #IPV6_DEFROUTE=yes #IPV6_FAILURE_FATAL=no #IPV6_ADDR_GEN_MODE=stable-privacy NAME=br0 #UUID=af60e6bd-e824-44fa-a816-763e6e977ae6 DEVICE=br0 ONBOOT=yes IPADDR=192.168.0.65 PREFIX=24 GATEWAY=192.168.0.10 DNS1=213.117.155.12 DNS2=213.117.155.10 [root@baremetainhousebaseserver1 network-scripts]# cat ifcfg-em1 TYPE=Ethernet PROXY_METHOD=none BROWSER_ONLY=no BOOTPROTO=static DEFROUTE=yes IPV4_FAILURE_FATAL=no IPV6INIT=yes IPV6_AUTOCONF=yes IPV6_DEFROUTE=yes IPV6_FAILURE_FATAL=no IPV6_ADDR_GEN_MODE=stable-privacy NAME=em1 UUID=af60e6bd-e824-44fa-a816-763e6e977ae6 DEVICE=em1 ONBOOT=yes BRIDGE=br0 IPADDR=192.168.0.35 PREFIX=24 GATEWAY=192.168.0.10 DNS1=213.117.155.12 DNS2=213.117.155.10 [root@baremetainhousebaseserver1 network-scripts]# I use the below command to launch KVM guest VM #virt-install --name=qubecrafter02 --file=/var/lib/libvirt/images/apprafter02centos7.img --file-size=50 --nonsparse --vcpus=2 --ram=8096 --network=bridge:br0 --os-type=linux --os-variant=rhel7 --graphics none --location=/var/lib/libvirt/isos/CentOS-7-x86_64-DVD-1810.iso --extra-args="console=ttyS0" I do vim /etc/sysconfig/network-scripts/ifcfg-eth0 on guestosvm1 [root@guestosvm1 network-scripts]# cat ifcfg-eth0 TYPE=Ethernet PROXY_METHOD=none BROWSER_ONLY=no BOOTPROTO=static DEFROUTE=yes IPV4_FAILURE_FATAL=no IPV6INIT=yes IPV6_AUTOCONF=yes IPV6_DEFROUTE=yes IPV6_FAILURE_FATAL=no IPV6_ADDR_GEN_MODE=stable-privacy NAME=eth0 UUID=805ff146-ecc1-460a-a7e2-e35eb19814c2 DEVICE=eth0 ONBOOT=yes IPADDR=192.168.0.66 PREFIX=24 GATEWAY=192.168.0.10 DNS1=213.117.155.12 DNS2=213.117.155.10 [root@guestosvm1 network-scripts]# I am confused between bridge and ethernet networking.
