Re: [libvirt] [Qemu-devel] incorrect memory size inside vm

The rest of visible memory is eaten by reserved kernel areas, for us
this was a main reason to switch to a hotplug a couple of years ago.
You would not be able to scale a VM by an order of magnitude with
regular balloon mechanism without mentioned impact, unfortunately.
Igor Mammedov posted hotplug-related patches for 2.6.32 a while ago,
though RHEL6 never adopted them by some reason.
Hmm.. Thanks for info, from what version of kernel memory hotplug works?
