Hi,
In my office I have an HP Proliant server running CentOS 7. It's a minimal install without GUI. The machine has two network interface cards, and for now it's acting as gateway/firewall, and it's running ntpd, Dnsmasq and Rsnapshot.
I'd like this machine to also be a KVM virtualization host, so I installed qemu-kvm and libvirt. The interface facing the LAN is enp3s0, so I created a virbr0 bridge like this.
# /etc/sysconfig/network-scripts/ifcfg-enp3s0 DEVICE=enp3s0 TYPE=Ethernet ONBOOT=yes BRIDGE=virbr0
And then:
# /etc/sysconfig/network-scripts/ifcfg-virbr0 DEVICE=virbr0 TYPE=Bridge ONBOOT=yes BOOTPROTO=static IPADDR=192.168.2.1 NETMASK=255.255.255.0
I replaced enp3s0 in my firewall script and in dnsmasq.conf and rebooted, and everything seems OK now... or almost. Here's an unexpected error I get.
# systemctl --failed UNIT LOAD ACTIVE SUB DESCRIPTION ● rpcbind.socket loaded failed failed RPCbind Server Activation Socket
This error appeared since I created my virbr0 interface, so I presume it has something to do with it. Unfortunately, I'm clueless.
Any suggestions?
Niki
