Cubic is a lightweight command line manager for virtual machines. It has a simple, daemonless and rootless design. All Cubic virtual machines run isolated in the user context. Cubic is built on top of QEMU, KVM and cloud-init. Examples: Create a new VM instance with: $ cubic create example --image ubuntu:noble Open a shell in the VM instance: $ cubic ssh example Alternatively, use `run` to execute the above commands in a single command: $ cubic run example --image ubuntu:noble Show all supported VM images: $ cubic images List previously created VM instances: $ cubic instances Show information about a VM instance: $ cubic show <instance> Execute a command in a VM instance: $ cubic exec <instance> <shell command> For more information, visit: https://cubic-vm.org/ The source code is located at: https://github.com/cubic-vm/cubic
