Run the following command to close any emulator instances you currently have open:
ffx emu stop --all
Start a new emulator instance:
ffx emu start --headless
When startup is complete, the emulator prints the following message and returns:
Logging to "{{ '<var>' }}$HOME{{ '</var>' }}/.local/share/Fuchsia/ffx/emu/instances/fuchsia-emulator/emulator.log" Waiting for Fuchsia to start (up to 60 seconds)........ Emulator is ready.
