How to correctly configure additional external ip, like ip virtual machines?

Question

KVM

Good afternoon.
We rented a server in one DC in Poland.
CentOS 7 OS + KVM virtualization
Got one ip with mask 255.255.255.252(/30) and gateway (respectively ip minus 1) and several additional ip with mask 255.255.255.255 (/32) and no gateway.
Here is the content of
/etc/sysconfig/network-scripts/ifcfg-br0

DEVICE=br0
STP=yes
TYPE=Bridge
BOOTPROTO=none
DEFROUTE=yes
IPV4_FAILURE_FATAL=no
IPV6INIT=yes
IPV6_AUTOCONF=yes
IPV6_DEFROUTE=yes
IPV6_FAILURE_FATAL=no
NAME=br0
UUID=eb49b3d7-ce67-4a65-a70d-26cb22e8379b
ONBOOT=yes
BRIDGING_OPTS=priority=32768
IPADDR=выданный мне основной ip
NETMASK=255.255.255.252
GATEWAY=шлюз к этому ip
DNS1=8.8.8.8
IPV6_PEERDNS=yes
IPV6_PEERROUTES=yes

/etc/sysconfig/network-scripts/ifcfg-eno1

TYPE=Ethernet
NAME=eno1
UUID=487a6cea-e2a3-495a-99fc-6302e6504c59
DEVICE=eno1
ONBOOT=yes
BRIDGE=br0

How to configure external ip on interfaces of guest systems in this case?
There was an experience of setting up such configurations when the DC issued separate ip and gateways to them.
I don’t really understand how to act now, but the deadlines are burning.
I would be very grateful for help.

Answer 1

XXXX - host ip. yyyy - do virtual machines in a virtual machine like this
:
ip ro add xxxx/32 dev ethX src yyyy
ip ro replace default via xxxx dev ethX
How to do this in your system - you will figure it out yourself. ip ro is universal, of course - the question is how to start it when the network starts.
Otherwise, everything is the same - bridge, ip_forward=1 and let's go.
