     network_size 256 vlan 1
Remove a network, first disassociate it to a project:
$ sudo novamanage project scrub projectname
$ sudo novamanage network delete [cidr]
List networks:
$ sudo novamanage network list
Add a floating IPs address range:
$ sudo novamanage floating create pool [mypool]
     ip_range 172.17.1.32/27

Add a floating to your tenant (you will get a floating IP address, but unused):
$ nova floatingipcreate [mypool]
Associate IP to an instance (specific tenant, according to your credentials)
$ nova addfloatingip [myinstance] [ip]
Check the status of the floating IPs (tenant related):
$ nova floatingiplist
List all instances running on every compute node:
$ sudo novamanage vm list | column t
1.2 Common
Add a new security group:
$ nova secgroupcreate webserver "Web server running"
Add rule to this group:
$ nova secgroupaddrule webserver tcp 80 80 0.0.0.0/0

$ chmod 600 *.pem
List instances from the tenant in your credential:
$ nova list
Boot a new instance:
$ nova boot flavor [flavorid] image [imageid] key_name [key1]
security_groups [default] [instancename]
Delete an instance:
$ nova delete [INSTANCE_ID]
Take a snapshot from an instance but first commit the buffer cache to disk:
myinstance:~$ sync
myinstance:~$ sudo echo 3 | sudo tee /proc/sys/vm/drop_caches
$ nova imagecreate [instanceid] [snapshotname]
Get precise information about a specific instance:
$ nova show [instancename]
Perform a block_migration:

$ nova volumelist
Attach volume to instance:
$ nova volumeattach [instanceid] [volname] /dev/vdc
5. Neutron
List floating ip:
$ neutron floatingiplist
Create router:
$ neutron routerlist
List all router:
$ neutron routerlist
List all subnet:
$ neutron subnetlist

Load Balance as a Service:
$ neutron lbpoolcreate lbmethod ROUND_ROBIN name mypool
      protocol HTTP subnetid [subnetid]
$ neutron lbmembercreate address [server1ip] protocolport 80 mypool
$ neutron lbmembercreate address [server2ip] protocolport 80 mypool
$ neutron lbhealthmonitorcreate delay 3 type HTTP maxretries 3
      timeout 3
$ neutron lbhealthmonitorassociate [healthmonitoruuid] mypool
$ neutron lbvipcreate name myvip protocolport 80 protocol HTTP
      subnetid [subnetid] mypool
6. Heat
