Message-Id: <1415289167-24661-1-git-send-email-imammedo@redhat.com> Date: Thu, 6 Nov 2014 15:52:47 +0000 From: Igor Mammedov <imammedo@...hat.com> To: linux-kernel@...r.kernel.org Cc: pbonzini@...hat.com, kvm@...r.kernel.org, x86@...nel.org 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.
