Virtual Machine single NIC set two IP

First, modify the virtual network card configuration in the virtual machine.

cd/ect/sysconfig/network-scripts/

VI Ifcfg-eth0

Change Bootproto=static

CP Ifcfg-eth0 Ifcfg-eth0:1 # Copying a configuration file #

VI ifcfg-eth0:1

Change Device=eth0:1

Change ipaddr= to new IP

Service Network restart

Second, find the network control node

Using neutron agent-list in the control node, locate the Metadata agent node, which is the network control node.

Third, login network control node

Neutron port-update $portID--allowed-address-pairs type=dict list=true ip_address= New IP

Portid can be obtained by:

Neutron Port-list | grep "Legacy IP" search

Other:

Can bind multiple
Neutron port-update ad33c996-b5e9-4c91-8f73-6d14ab3827d6--allowed-address-pairs type=dict list=true ip_address= 10.133.16.242 ip_address=10.133.16.241 ip_address=10.133.16.243

After tying can be viewed according to Port-id
Neutron port-show Portid
Neutron port-show Ad33c996-b5e9-4c91-8f73-6d14ab3827d6

Built-in virtual machine add NIC
Nova Interface-attach--net-id 3e680906-75d7-4d97-aa5f-9466bc1fd811 880E89FD-E2F3-4E67-AC32-7F12267BD6A2

The first string is the network ID, and the second string is the virtual machine ID, which can be found in the portal.
