gnt-os - instance operating system administration


gnt-os command [ arguments... ]


The gnt-os is used for managing the list of available operating system flavours for the instances in the ganeti cluster.



Gives the list of available/supported OS to use in the instances. When creating the instance you can give the OS-name as an option.


This command will help you see why an installed OS is not available in the cluster. The list command shows only the OS-es that the cluster sees available on all nodes. It could be that some OS is missing from a node, or is only partially installed, and this command will show the details of all the OSes and the reasons they are or are not valid.


Report bugs to or contact the developers using the ganeti mailing list <>.
