cubic 0.18.0

Cubic is a lightweight command line manager for virtual machines. It has a simple, daemon-less and rootless design. All Cubic virtual machines run isolated in the user context. Cubic is built on top of QEMU, KVM and cloud-init. https://cubic-vm.org https://github.com/cubic-vm/cubic Show all supported images: $ cubic images Create a new virtual machine instance: $ cubic create mymachine --image ubuntu:noble List all virtual machine instances: $ cubic instances Start an instance: $ cubic start <instance name> Stop an instance: $ cubic stop <instance name> Open a shell in the instance: $ cubic ssh <machine name> Copy a file from the host to the instance: $ cubic scp <path/to/host/file> <machine>:<path/to/guest/file> Copy a file from the instance to the hots: $ cubic scp <machine>:<path/to/guest/file> <path/to/host/file>
