OpenNebula provides six commands to interact with the system:

• onevm: to submit, control and monitor virtual machines
• onehost: to add, delete and monitor hosts
• onevnet: to add, delete and monitor virtual networks
• oneuser: to add, delete and monitor users
• oneimage: to add, delete and control images
• onecluster: to add, delete and control clusters
• oneauth: tools to manage authentication and authorization

These are the options shared by some of the commands:

• -l, –list x,y,z: Selects columns to display with list command.
• –list-columns: Information about the columns available to display, order or filter.
• -o, –order x,y,z: Order by these columns, column starting with - means decreasing order.
• -f, –filter x,y,z: Filter data. An array is specified with column=value pairs.
• -d, –delay seconds: Sets the delay in seconds for top command.
• -h, –help: Shows help information.
• –version: Shows version and copyright information.
• -v, –verbose: Tells more information if the command is successful
• -x, –xml: Returns xml instead of human readable text
• -n, –no-hash: Store plain password into the database

Number ranges can also be specified this way:

• [<start>-<end>]: generates numbers from start to end
• [<start>+<count>]: generates a range that starts with the number provided and has count number of elements

If <start>'s first digit is 0 then it will pad the numbers generated with 0 to the same size as the last element in the range.

Example:

[9-11]:   9 10 11
[09-11]: 09 10 11
[8+3]:    8  9 10
[08+3]:  08 09 10
