Improve VM setup and IP detection logic

Suppress libguestfs warnings, enable and start QEMU Guest Agent during first boot, and enhance VM IP address detection by waiting for the guest agent to become available and adding a fallback method. These changes improve reliability and provide better feedback during VM initialization.
