Title:
[Hyper-V] Disable CONFIG_HOTPLUG_CPU in linux-azure
Status in linux-azure package in Ubuntu:
New
Status in linux-azure source package in Bionic:
In Progress
Bug description:
While Hyper-V may present all potential CPUs via ACPI MADT, CPU
add/remove is not supported. This results in kernel data structures
created for the largest potential size based on the number of CPUs
when those CPUs will never be added during the time the guest is up
(it can certainly be resized when it's down and deallocated). Please
disable CONFIG_HOTPLUG_CPU in linux-azure.
