Hi, This is v5 of memory hotplug support patchset for PowerPC sPAPR guests.
This patchset applies on spapr-next branch of David Gibson's tree with pc_dimm_pug reorg+NUMA node lookup patchset v4: http://lists.nongnu.org/archive/html/qemu-devel/2015-06/msg07174.html Changes in v6 ------------- - Rebased on top of latest pc_dimm_reorg+NUMA node lookup patchset v4. - Instead of silently disabling memory hotplug, refuse to boot with memory configurations where RAM size or maxmem size or node memory size isn't aligned to SPAPR_MEMORY_BLOCK_SIZE(256MB). (2/6) - Pushed a recoverable error check (hotplug mem size not aligned to 256MB) from spapr_add_lmbs() down to spapr_memory_plug() so that we can pass error_abort to spapr_add_lmbs() and let it abort in case of errors. This is in line with Igor's observation that we shouldn't fail and hence shouldn't try recovery after we have done guest visible changes.
