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.
modify [ -H HYPERVISOR [ : option=value ... ] ] OS
This command will allow you to modify OS parameters. At the moment we
just support per-os-hypervisor settings. You can run modify -H with the
same syntax as in gnt-cluster init to override default hypervisor
parameters of the cluster for specified OS argument.
Note: The OS doesn’t have to exists. This allows preseeding the
settings for OSes not yet known to gnt-os.
