CHANGELOG.md

• 0.4.2:
  • Fix a large bug with qemu launches; I had misunderstood what -snapshot was for, VMs launched with this flag will not retain their state.
  • Instead of letting qemu spit out a nasty error, we now detect port forwards already in use and block the run.
• 0.4.1:
  • Named snapshots are now under the snapshot sub-commmand structure and provide the following features for now:
    • emu snapshot save <vm> <name> saves a new snapshot to the VM. The snapshot's name must not already be saved.
    • emu snapshot load <vm> <name> loads snapshot into the VM's current running state.
    • emu snapshot delete <vm> <name> deletes snapshot state.
    • There is no listing command yet; you must remember your names for now. One thing at a time! :)
  • emu reset performs a hard reset of a VM.
  • emu restart shuts the VM down and waits, and then spawns it again. Will re-create windows, and should not be used with supervisors/systemd.
• 0.4.0:
  • Snapshots! The following commands now manage a single, easy-to-use snapshot for quickly managing state.
    • emu save <vm> will save your VM's current state
    • emu load <vm> will load the saved state (as many times as you want)
    • emu clear-state <vm> will clear the saved state.
    • Notes:
      • Lots of operations in a rush seem to crash qemu easily. Still looking into this.
      • You must clear a saved state before creating a new one. Saving twice results in an error. May change this.
  • emu clone now has a cool progress meter for copying large files
    • Also, you can now pass -c to copy the configuration as well as the image data. Default is off.
  • Underpinnings now include a semi-comprehensive QMP client for qemu.
• 0.3.0:
  • emu shutdown now waits for qemu to quit before quitting itself.
    • Provide the -n flag to return to the shell instead of waiting.
  • Allow emu ssh to supply arguments to the underlying ssh command.
  • Code rewrite: most code has been replaced and re-organized for future enhancements including polymorphism amongst operating systems and hypervisors.
• 0.2.0:
  • emu list-disks to list disks for a VM.
  • emu import always creates a new disk when importing.
  • emu clone copies all images from one VM to the new destination.
  • emu delete now takes an optional parameter to delete individual VM images.
  • emu config copy allows you to copy pre-configured settings from one VM to another.
  • emu create -a can now be used to add disks to an existing VM.
  • Disks are now created stamped with the epoch seconds they were created at.
  • emu list -r lists running VMs only.
  • Rename command; rename vms you manage.
  • Better error messages in some situations.
• 0.1.1:
  • Tracking of run state; specialized for systemd or ad-hoc qemu runs
    • Reflected in lists and also with a new command is-active
• 0.1.0:
  • First release (after 4 years of sitting on the shelf)
