Add a command to Finder services in Mac OSX to open a folder in VS Code
- Open Automator
- File -> New -> Service
- Change "Service Receives" to "files or folders" in "Finder"
- Add a "Run Shell Script" action
- Change "Pass input" to "as arguments"
- Paste the following in the shell script box: open -n -b "com.microsoft.VSCode" --args "$*"
- Save it as something like "Open in Visual Studio Code"

Setting up Qemu with a tap interface

Setting up Qemu with a tap interface

There are two parts to networking within QEMU:

  • The virtual network device that is provided to the guest (e.g. a PCI network card).
  • The network backend that interacts with the emulated NIC (e.g. puts packets onto the host's network).

Example: User mode network
