[pve-devel] [PATCH qemu-server 00/10] rework memory hotplug + virtiomem

[Alexandre Derumier]

This patch series rework the current memory hotplug + virtiomem.

memory option now have extra options:

memory: [[current=]<integer>] [,max=<enum>] [,virtio=<1|0>]
ex: memory: current=1024,max=131072,virtio=1


patches 1-2: add a memory parser

patches 3-7: add the max option with 64 static dimm hotplug

for classic memory hotplug, when maxmemory is defined,
we use 64 fixed size dimm.
The max option is a multiple of 64GB.

patches 8-9: add virtio-mem

The virtio option enable new virtio-mem support,
instead of plugging dimm, it's add/removed block inside
big dimm.
virtio-mem can use 32000 blocks, the blocksize is compute from
max memory.

patch10: hotplug fix

Alexandre Derumier (10):
  test: add memory tests
  add memory parser
  config: memory: add 'max' option
  memory: add get_static_mem
  memory: get_max_mem: use config memory max
  memory: use 64 slots && static dimm size with max is defined
  test: add memory-max tests
  memory: add virtio-mem support
  tests: add virtio-mem tests
  memory: fix hotplug with virtiomem && maxmem
