In this new blog post, we’ll cover all the main Nutanix AHV CLI commands that allow you to perform some checks on your virtual machines using the command line.
All the commands in this article can be run via SSH from any CVM in the cluster.
Display the list of virtual machines
To display the list of virtual machines on the Nutanix cluster, simply run the following command:
acli vm.list
This will show you all the VMs present on the cluster, without the CVMs:
nutanix@NTNX-S348084X9211699-B-CVM:192.168.84.22:~$ acli vm.list
VM name VM UUID
LINUX 88699c96-11a5-49ce-9d1d-ac6dfeff913d
NTNX-192-168-84-200-PCVM-1760699089 f659d248-9ece-4aa0-bb0c-22a3b3abbe12
vm_test 9439094a-7b6b-48ca-9821-a01310763886
As you can see, I only have two virtual machines on my cluster:
My Prism Central
A newly deployed “LINUX” virtual machine
A test virtual machine
A handy command to quickly retrieve all virtual machines and their respective UUIDs. Now let’s see how to retrieve information about a specific virtual machine.
Retrieving Virtual Machine Information
To display detailed information about a virtual machine, use the following command:
acli vm.get VM_NAME
Using the example of my “LINUX” virtual machine, this returns the following information:
As you can see, this returns all the information about a virtual machine. It is possible to filter some of the information returned with certain commands. Here are the ones I use most often:
acli vm.disk_get VM_NAME : to retrieve detailed information of all disks of a virtual machine
acli vm.snapshot_list VM_NAME : to retrieve the list of snapshots associated with a virtual machine
nutanix@NTNX-S348084X9211699-B-CVM:192.168.84.22:~$ acli vm.snapshot_list LINUX
Snapshot name Snapshot UUID
SNAPSHOT_BEFORE_UPGRADE e7c1e84e-7087-42fd-9e9e-2b053f0d5714
You now know almost everything about verifying your virtual machines.
In the Maxi Best Of Nutanix CLI series, the previous two articles covered checking the network configuration of a Nutanix cluster and managing subnets.
In this new article, we’ll cover managing storage containers via CLI commands on your Nutanix clusters…
All the commands in this article must be executed from one of the cluster’s CVMs and work on a cluster running AOS 6.10+.
Check the containers
To check the status of your storage containers, the simplest command is:
ncli container list
This command will allow you to display all the information related to all the containers in your cluster.
If you want to display a specific container, you can pass the name (the simplest method) or the ID of your container if you have it as a parameter:
ncli container list name=NAME
ncli container list id=ID
Finally, one last command to display only the usage statistics of your containers:
ncli container list-stats
Renaming a Container
To rename a storage container, it must be completely empty.
Renaming a storage container can be done using the following command:
WARNING: There are two containers created by default when deploying your cluster: “SelfServiceContainer” and “NutanixManagementShare”. Do not attempt to rename them!
Creating a Container
It’s also possible to create storage containers using the CLI:
The “name” and “sp-name” parameters are the only required parameters when running the command. This will allow you to create a base container on the selected storage pool with the following parameters:
No data optimization mechanism
No restrictions/reservations
The default replication factor
But the container creation command can be very useful if you need to create storage containers in batches, for example, if you’re hosting multiple clients on a cluster, each with an allocated amount of storage space!
For example, to create a storage container with the following parameters:
A container with the associated characteristics will then be created:
Modifying Container Settings
An existing container can also be modified. You can modify almost everything in terms of settings, from data optimization mechanisms to reserved/allocated sizes, replication factors, and more.
For all the settings, please refer to the official documentation (link at the bottom of the page).
Deleting a Container
Deleting a container is quite simple, but requires that all files stored within it be deleted or moved first. Deleting a container is done using the following command:
ncli container remove name=NAME
It may happen that despite deleting or moving your VM’s vdisks, the deletion is still refused. This is often due to small residual files.
You must then add the “ignore-small-files” parameter to force the deletion:
WARNING: There are two containers created by default when deploying your cluster: “SelfServiceContainer” and “NutanixManagementShare”. Do not attempt to delete them!
Whether you need to perform specific or repetitive operations, troubleshoot, or gain a more detailed view, the CLI commands for a Nutanix cluster will be your best allies.
In this article, I offer a summary of the best commands for performing all network configuration checks on a Nutanix cluster, whether at the cluster, host, CVM, or virtual machine level.
You must have an AOS 6.10+ cluster to execute some commands of this guide.
A. Using Nutanix acli commands from any CVM in the Nutanix AHV cluster
List the status of the host interfaces:
acli net.list_host_nic 192.168.84.11 @IP_HOST_AHV
Result:
List all vSwitches currently configured on the cluster:
acli net.list_virtual_switch
Result:
You can list the configuration of a particular vSwitch by passing it as an argument to the command:
acli net.list_virtual_switch vs1
List all subnets created on the cluster:
acli net.list
Result:
List the VMs attached to a particular subnet:
acli net.list_vms SUBNET
B. Via the Nutanix manage_ovs script from any CVM in the Nutanix AHV cluster
List the interface status of an AHV host:
manage_ovs show_interfaces
Result:
You can also list the interface status of all hosts in the cluster:
allssh "manage_ovs show_interfaces"
List the status of an AHV host’s uplinks (bonds):
manage_ovs show_uplinks
Result :
You can also list the uplink (bond) status of all AHV hosts in the cluster:
allssh "manage_ovs show_uplinks"
Display LLDP information of an AHV host’s interfaces:
manage_ovs show_lldp
Result:
You can also view LLDP information for the interfaces of all AHV hosts in the cluster:
allssh "manage_ovs show_lldp"
Show currently created bridges on an AHV host:
manage_ovs show_bridges
Result :
You can also view the bridges currently created on all AHV hosts in the cluster:
allssh "manage_ovs show_bridges"
Show the mapping of CVM interfaces to those of AHV hosts:
manage_ovs show_cvm_uplinks_map
Result :
You can also view the interface mapping of CVMs on all AHV hosts in the cluster:
allssh "manage_ovs show_cvm_uplinks_map"
C. Using the Open vSwitch command from any host in a Nutanix AHV cluster
List the existing bridges of an AHV host:
ovs-vsctl list-br
Result :
List all interfaces attached to a particular bridge of an AHV host:
ovs-vsctl list-ifaces br0
Result:
Display the configuration of an AHV host’s port bond:
ovs-vsctl list port br0-up
Result :
Display the configuration and status of a bond on an AHV host:
ovs-appctl bond/show br0-up
Result:
Display information about the status of a LACP-configured bond on an AHV host:
ovs-appctl lacp/show br1-up
Many thanks to Yohan for the article idea and the helping hand!
Here is a quick procedure to install Nutanix Guest Tools manually on your Linux virtual machines (Rocky Linux, RHEL, CentOS…) using the command line.
What are Nutanix Guest Tools?
NGT is a set of software features installed on a virtual machine (VM) and a Nutanix CVM. A Nutanix Guest Agent publishes information about the virtual machine to the Nutanix cluster, such as the guest operating system type, the virtual machine’s mobility status, and the Volume Shadow Copy Service (VSS). The Nutanix Guest Agent is installed on both Windows and Linux guest virtual machines.
Installing Nutanix Guest Tools
Connect to your Nutanix cluster on Prism Central, go to the list of virtual machines, right-click on the virtual machine on which you want to install NGTs, and click “Install NGT”:
On the next screen, in my case no need to change anything, click on “Confirm and Enter Password”:
Don’t touch anything on this screen, just click “Skip and Mount” at the bottom left:
The ISO is mounted, now we move on to the command lines!
The command first returns general information about the cluster (name, ID, UUID, Version, IPs, etc.):
