Here's what I typically use for my guix system containers:

  (bootloader (bootloader-configuration
               (bootloader grub-bootloader)
               (target "does-not-matter")))
  (file-systems %base-file-systems)
  ;; No firmware for VMs.
  (firmware '())
  ;; We don't need any packages inside the container.
  (packages '())

Based on other discussions, it seems that (bootloader #f) may also work.
