📄️Daemon Virtual Machine

This section introduces how to set virtual machines to start automatically with the host operating system. Virtual machine auto-start is achieved by setting the virtual machine as a daemon virtual machine. If a virtual machine is set as a daemon virtual machine, every time host-agent starts, it will ensure that this virtual machine is in running state.
