From 1d4e7e3c0bca747d0fc54069a6ab8393349431c0 Mon Sep 17 00:00:00 2001 From: Igor Mammedov Date: Thu, 6 Nov 2014 15:52:47 +0000 Subject: [PATCH] kvm: x86: increase user memory slots to 509 With the 3 private slots, this gives us 512 slots total. Motivation for this is in addition to assigned devices support more memory hotplug slots, where 1 slot is used by a hotplugged memory stick. It will allow to support upto 256 hotplug memory slots and leave 253 slots for assigned devices and other devices that use them.
