gnt-os(8) Version 2.5.2 gnt-os(8) Name gnt-os - Instance operating system administration Synopsis gnt-os {command} [arguments...] DESCRIPTION
The gnt-os is used for managing the list of available operating system flavours for the instances in the Ganeti cluster. COMMANDS
list 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. Note that hidden or blacklisted OSes are not displayed by this command, use diagnose for showing those. diagnose 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. info This command will list detailed information about each OS available in the cluster, including its validity status, the supported API ver- sions, the supported parameters (if any) and their documentations, etc. modify [-H HYPERVISOR:option=value[,...]] [--hidden=yes|no] [--blacklisted=yes|no] {OS} This command will allow you to modify OS parameters. To modify the per-OS hypervisor parameters (which override the global hypervisor parameters), 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. To modify the hidden and blacklisted states of an OS, pass the options --hiddenyes|no, or respectively --blacklisted .... The 'hidden' state means that an OS won't be listed by default in the OS list, but is available for installation. The 'blacklisted' state means that the OS is not listed and is also not allowed for new instance creations (but can be used for reinstalling old instances). Note: The given operating system doesn't have to exists. This allows preseeding the settings for operating systems not yet known to gnt-os. REPORTING BUGS
