List instances, check status of instance

$ nova list

List images

$ nova image-list

List flavors

$ nova flavor-list

Boot an instance using flavor and image names (if names are unique)

$ nova boot --image IMAGE --flavor FLAVOR INSTANCE_NAME

$ nova boot --image cirros-0.3.1-x86_64-uec --flavor m1.tiny


Login to instance

# ip netns

# ip netns exec NETNS_NAME ssh USER@SERVER

# ip netns exec qdhcp-6021a3b4-8587-4f9c-8064-0103885dfba2

  ssh cirros@


In CirrOS the password for user cirros is “cubswin:)” tanpa quotes.

Show details of instance

$ nova show NAME

$ nova show MyFirstInstance

View console log of instance

$ nova console-log MyFirstInstance

$ nova pause NAME

$ nova pause volumeTwoImage


$ nova unpause NAME


$ nova suspend NAME


$ nova resume NAME


$ nova stop NAME


$ nova start NAME


$ nova rescue NAME

$ nova rescue NAME --rescue_image_ref RESCUE_IMAGE


$ nova resize NAME FLAVOR

$ nova resize my-pem-server m1.small

$ nova resize-confirm my-pem-server1


$ nova rebuild NAME IMAGE

$ nova rebuild newtinny cirros-qcow2


$ nova reboot NAME

$ nova reboot newtinny

Inject user data and files into an instance

$ nova boot --user-data FILE INSTANCE

$ nova boot --user-data userdata.txt --image cirros-qcow2

  --flavor m1.tiny MyUserdataInstance2


To validate that the file was injected, use ssh to connect to the instance, and look in /var/lib/cloud for the file.

Inject a keypair into an instance and access the instance with that keypair

Create keypair

$ nova keypair-add test > test.pem

$ chmod 600 test.pem

Start an instance (boot)

$ nova boot --image cirros-0.3.0-x86_64 --flavor m1.small

  --key_name test MyFirstServer

Use ssh to connect to the instance

# ip netns exec qdhcp-98f09f1e-64c4-4301-a897-5067ee6d544f

  ssh -i test.pem cirros@

Manage security groups

Add rules to default security group allowing ping and SSH between instances in the default security group

$ nova secgroup-add-group-rule default default icmp -1 -1

$ nova secgroup-add-group-rule default default tcp 22 22



Create network

$ neutron net-create NAME

Create a subnet

$ neutron subnet-create NETWORK_NAME CIDR

$ neutron subnet-create my-network



Used to manage volumes and volume snapshots that attach to instances.

Create a new volume

$ cinder create SIZE_IN_GB --display-name NAME

$ cinder create 1 --display-name MyFirstVolume

Boot an instance and attach to volume

$ nova boot --image cirros-qcow2 --flavor m1.tiny MyVolumeInstance

List volumes, notice status of volume

$ cinder list

Attach volume to instance after instance is active, and volume is available

$ nova volume-attach INSTANCE_ID VOLUME_ID auto

$ nova volume-attach MyVolumeInstance 573e024d-5235-49ce-8332-be1576d323f8 auto


On the Xen Hypervisor it is possible to provide a specific device name instead of automatic allocation. For example:

$ nova volume-attach MyVolumeInstance 573e024d-5235-49ce-8332-be1576d323f8 /dev/vdb

This is not currently possible when using non-Xen hypervisors with OpenStack.

Manage volumes after login into the instance.

List storage devices

# fdisk -l

Make filesystem on volume

# mkfs.ext3 /dev/vdb

Create a mountpoint

# mkdir /myspace

Mount the volume at the mountpoint

# mount /dev/vdb /myspace

Create a file on the volume

# touch /myspace/helloworld.txt

# ls /myspace

Unmount the volume

# umount /myspace



Display information for the account, container, or object
