Whoosh... technically it is possible but it would be an incompatible fork for the upstreams for both SeaBIOS and Qemu, because the generic way of plugging DIMMs in is available down to at least generic 2.6.32. Except may be Centos where broken kabi would bring great consequences, it may be better to just provide a backport repository with newer kernels, but it doesn`t sound very optimistic. For the history records, the initial hotplug support proposal provided by Vasilis Liaskovitis a couple of years ago worked in an exact way you are suggesting to, but its resurrection would mean emulator and rom code alteration, as I said above.
Ok, i'm try to build latest libvirt and check all oses for memory hotplug support =). -- Vasiliy Tolstov, e-mail: v.tolstov@selfip.ru
