Title:
  no memory hot-plugging in cloud-images

Status in cloud-images:
  New
Status in linux package in Ubuntu:
  Confirmed

Bug description:
  Memory hot-plugging is not working with public cloud-images. Error with dmesg 
shows:
  [  184.544535] acpi PNP0C80:00: Enumeration failure

  checking kernel configuration:
  root@ubuntu:/boot# uname -r
  5.4.0-1038-kvm
  root@ubuntu:/boot# grep CONFIG_ACPI_HOTPLUG_MEMORY config-5.4.0-1038-kvm
  # CONFIG_ACPI_HOTPLUG_MEMORY is not set

  Obviously the necessary kernel configuration for ACPI memory hotplug
  is missing.
