[libvirt] [PATCH 0/8] logically memory hotplug via guest agent

Logically memory hotplug via guest agent, by enabling/disabling memory blocks. The corresponding qga commands are: 'guest-get-memory-blocks', 'guest-set-memory-blocks' and 'guest-get-memory-block-info'. detailed flow: 1 get memory block list, each member has 'phy-index', 'online' and 'can-offline' parameters 2 get memory block size, normally 128MB or 256MB for most OSes 3 convert the target memory size to memory block number, and see if there's enough memory blocks to be set online/offline. 4 update the memory block list info, and let guest agent to set memory blocks online/offline. Note that because we hotplug memory logically by online/offline MEMORY BLOCKS, and each memory block has a size much bigger than KiB, there's a deviation with the range of (0, block_size). block_size may be 128MB or 256MB or etc., it differs on different OSes.
