Status in cloud-images:
New
Status in linux package in Ubuntu:
Incomplete
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.
