This guide will walk you through setting up a system service to automatically launch your desired VirtualBox VMs, saving you precious time and effort.

Configure Autostart Properties

• Create a file named autostart.properties in the folder C:\Users\Admin\.VirtualBox.
• Inside the file, define the following:

1
2
3
4
5

default_policy = deny
Admin = {
    allow = true
    startup_delay = 10
}

• default_policy = deny: This sets the default policy to deny all autostarts.
• Admin = { allow = true; startup_delay = 10 }: This allows the user “Admin” to start VMs with a 10-second delay.

Set System Variable

• Create a new system variable named VBOXAUTOSTART_CONFIG and set its value to C:\Users\Admin\.VirtualBox\autostart.properties.

Install the VirtualBox Autostart Service

• Navigate to the VirtualBox installation directory: cd "C:\Program Files\Oracle\VirtualBox"
• Run the following commands:

1
2

.\VBoxAutostartSvc.exe install --user=Admin
.\VBoxManage.exe modifyvm "virtual-pc" --autostart-enabled on

• Replace "virtual-pc" with the actual name of your VM you want to autostart.

Check and Start the Service

• Use the sc command to check the service status: sc query VBoxAutostartSvcadmin-pcadmin
• Start the service: sc start VirtualBox Autostart Service VBoxAutostartSvcadmin-pcadmin

Congratulations! Your VirtualBox VM is now set to autostart when your system boots.

In Bash, you can trim whitespace characters from a variable using various methods, as shown in your code. Here’s a breakdown of the different approaches:

1. Remove Leading and Trailing White Spaces:

   1 2	NEW_VARIABLE="$(echo -e "${VARIABLE_NAME}" | tr -d '[:space:]')" # NEW_VARIABLE='aaa bbb'

   This method uses the tr command to delete all whitespace characters, both leading and trailing, in the variable VARIABLE_NAME.

2. Remove Only Leading White Spaces:

   1 2	NEW_VARIABLE="$(echo -e "${VARIABLE_NAME}" | sed -e 's/^[[:space:]]*//')" # NEW_VARIABLE='aaa bbb '

   Here, sed is used to remove only the leading whitespace characters from the variable.
