This command boots a virtual machine with QEMU, allocates 3 GB of RAM, and connects to it with a Spice server using the Spice client, while also configuring various settings such as CPU, graphics, network, and disk image.

The command boots a virtual machine using qemu-system-x86_64 with specified settings for CPU, memory, and graphics. It then connects to the VM using the Spice client, allowing remote access and managing the VM through a graphical interface.

QEMU and Spice Server Command

This code is a command that boots a virtual machine (VM) using qemu-system-x86_64 and connects to it with a Spice server.

Components:

• qemu-system-x86_64: The QEMU emulator.
• Options:
  • -smp 3: Specifies the number of CPU sockets to 3.
  • -cpu host: Uses the host's CPU type.
  • -m 3G: Allocates 3 GB of RAM.
  • -vga qxl: Uses the QXL graphics card.
  • -spice: Enables Spice protocol.
  • port=5924: Specifies the Spice port to 5924.
  • disable-ticketing: Disables ticketing for remote access.
• -drive: Specifies a disk image.
  • file=/Users/briancullinan/VirtualBox\ VMs/Ubuntu/Ubuntu.vmdk: The disk image file.
  • if=virtio: Uses the VirtIO disk interface.
• -net nic and -net user: Creates a virtual network interface.
  • model=virtio: Uses the VirtIO network interface.
  • hostname=ubuntuvm: Sets the hostname of the VM.
• -monitor stdio: Connects the QEMU monitor to the console.
• -name "Ubuntu": Sets the name of the VM.
• &&: Runs the second command only if the first is successful.
• spicy: The Spice client.
• --title Ubuntu: Sets the title of the window.
• 127.0.0.1: The IP address of the host machine.
• -p 5924: Connects to the Spice server on port 5924.
