	Meet one9s: A blazing fast, k9s-style TUI for OpenNebula (Go & Bubble Tea) (r/commandline) Hey folks, If you use OpenNebula, you probably know the daily struggle. Sure, the `onevm` CLI exists, but by default, only `oneadmin` can use it without fighting a permissions battle. That leaves regular users connecting to a VPN/tunnel, logging into the Sunstone web UI, hunting down their machine…	1	Sep 22, 2026

Terminal UI for OpenNebula cluster management
Monitor VMs, Hosts, Datastores, Manage ACLs and Quotas from your terminal
one9s.scszero.com | Documentation

one9s is a TUI (terminal user interface) for managing and monitoring OpenNebula clusters directly from your terminal, inspired by k9s and lazygit.

No Sunstone web UI. No Ruby CLI dependencies. Just a single binary that talks to the OpenNebula XML-RPC API.

https://github.com/user-attachments/assets/d30f232b-1ae5-4170-a2b8-efb1c4ba4879

Features

VM Management - monitor all VMs with state, CPU, memory, IP, host. Split view with detail pane showing full VM info.
VM Lifecycle - reboot, stop, resume, suspend, terminate directly from the terminal with confirmation modals.
Host Management - enable, disable, offline, delete, rename hosts. Detail view with CPU/Memory progress bars.
Datastore Monitoring - view storage pools with type, total capacity, used and free space.
ACL Rules - view and decode access control rules (user, resource, rights, zone) from hex to human-readable.
User Quotas - view and edit per-user quotas for VMs, CPU, Memory, Running VMs, Images, Size and Leases.
Fuzzy Search - / key for instant filtering on all tabs.
Vault Encryption - credentials encrypted with AES-256-GCM, safe from third-party access.
Cross-platform - single binary for Linux, macOS, Windows (amd64/arm64).

Quick Start

Download

curl -LO https://github.com/SergioZ3R0/one9s/releases/latest/download/one9s-linux-amd64.zip
unzip one9s-linux-amd64.zip
chmod +x one9s

Configure

mkdir -p ~/.one9s
cat > ~/.one9s/config << 'EOF'
ONE_XMLRPC=http://opennebula:2633/RPC2
ONE_AUTH=oneadmin:password
EOF
chmod 600 ~/.one9s/config

Or as a one-liner:

ONE_AUTH="oneadmin:password" ONE_XMLRPC="http://opennebula:2633/RPC2" ./one9s

Encrypted vault (recommended)

Store credentials encrypted with AES-256-GCM:

# Create encrypted vault
one9s vault init

# Run (prompts for vault password)
./one9s

# Or skip vault with direct env vars (no password prompt)
ONE_AUTH="oneadmin:password" ONE_XMLRPC="http://opennebula:2633/RPC2" ./one9s

Vault commands:

Command	Description
`one9s vault init`	Create new encrypted config
`one9s vault encrypt`	Encrypt existing plain config
`one9s vault decrypt`	Decrypt and display contents

Vault password can be set via ONE_VAULT_PASS env var to skip the prompt.

Run

./one9s

Key Bindings

Key	Action
`tab` / `shift+tab`	Next / previous tab
`↑/↓` / `j/k`	Navigate rows
`PgUp/PgDn` / `b/f`	Page up / page down
`g/G`	Go to start / end
`enter`	View details (VMs/Hosts split view)
`/`	Fuzzy search
`F5`	Refresh current view
`?`	Help

VM Actions (VMs tab)

Key	Action	Valid States
`r`	Reboot	ACTIVE
`s`	Stop	ACTIVE
`u`	Resume/Start	POWEROFF, SUSPENDED, STOPPED, UNDEPLOYED
`x`	Suspend	ACTIVE
`d`	Terminate (hard)	Any (with confirmation)

VM State Filters (VMs tab)

Key	Filter
`a`	All VMs
`i`	Active only
`o`	Stopped only
`p`	Poweroff only
`e`	Error only

Host Actions (Hosts tab)

Key	Action
`e`	Enable host
`d`	Disable host
`o`	Offline host (confirmation required)
`x`	Delete host (type `yes` to confirm)
`n`	Rename host (type new name)

Quota Actions (Quotas tab)

Key	Action
`e`	Edit user quota (form modal with VMs, CPU, Memory, etc.)

Permissions

one9s requires appropriate OpenNebula permissions. If an action fails due to insufficient permissions, you'll see a clear message like "permission denied: requires VM:MANAGE".

Action	Required Permission
View VMs, Hosts, Datastores, ACLs	VM:USE, HOST:USE, DS:USE, ACL:USE
Reboot, Stop, Suspend, Resume VM	VM:MANAGE
Terminate VM	VM:ADMIN
Enable/Disable/Offline Host	HOST:ADMIN
Delete/Rename Host	HOST:ADMIN
Edit Quotas	Quota:ADMIN
