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 for classic memory hotplug, when maxmemory is defined, we use 64 fixed size dimm. The max option is a multiple of 64GB. 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. Changelog v2: update differents patches based on Fiona comments. (I have send 2 others mails with comments not yet addressed) Biggest change is on virtio-mem, instead of trying to have same amount of memory on each virtiomem (some block could be unmovable and break unplug), we try to balance/dispatch remaining block on other available virtiomems. Also, the minimum blocksize supported by linux guest os is 4MB currently, even if virtiomem can use 2MB on qemu side. Changelog v3: - cleanup from last Fiona comments - classic hotplug : fix memory unplug - virtio-mem: split retry logic in a second optional patch (feel free to apply it later if needed) Changelog v4: - cleanup from last Fiona comments Changelog v5: - move dimm hot-unplug patches on top of the serie - cleanup from last Fiona comments Changelog v6: - qemu-server : rebase on last git qemu-server: Alexandre Derumier (10): add memory parser memory: add get_static_mem memory: use static_memory in foreach_dimm config: memory: add 'max' option memory: get_max_mem: use config memory max memory: use 64 slots && static dimm size when max is defined test: add memory-max tests memory: add virtio-mem support memory: virtio-mem : implement redispatch retry. tests: add virtio-mem tests PVE/API2/Qemu.pm | 41 +- PVE/QemuConfig.pm | 4 +- PVE/QemuMigrate.pm | 6 +- PVE/QemuServer.pm | 37 +- PVE/QemuServer/Helpers.pm | 3 +- PVE/QemuServer/Memory.pm | 422 +++++++++++++++--- PVE/QemuServer/PCI.pm | 8 + test/cfg2cmd/memory-max-128G.conf | 11 + test/cfg2cmd/memory-max-128G.conf.cmd | 86 ++++ test/cfg2cmd/memory-max-512G.conf | 11 + test/cfg2cmd/memory-max-512G.conf.cmd | 58 +++ test/cfg2cmd/memory-virtio-hugepages-1G.conf | 12 + .../memory-virtio-hugepages-1G.conf.cmd | 35 ++ test/cfg2cmd/memory-virtio-max.conf | 11 + test/cfg2cmd/memory-virtio-max.conf.cmd | 35 ++ test/cfg2cmd/memory-virtio.conf | 11 + test/cfg2cmd/memory-virtio.conf.cmd | 35 ++ 17 files changed, 744 insertions(+), 82 deletions(-) create mode 100644 test/cfg2cmd/memory-max-128G.conf create mode 100644 test/cfg2cmd/memory-max-128G.conf.cmd create mode 100644 test/cfg2cmd/memory-max-512G.conf create mode 100644 test/cfg2cmd/memory-max-512G.conf.cmd create mode 100644 test/cfg2cmd/memory-virtio-hugepages-1G.conf create mode 100644 test/cfg2cmd/memory-virtio-hugepages-1G.conf.cmd create mode 100644 test/cfg2cmd/memory-virtio-max.conf create mode 100644 test/cfg2cmd/memory-virtio-max.conf.cmd create mode 100644 test/cfg2cmd/memory-virtio.conf create mode 100644 test/cfg2cmd/memory-virtio.conf.cmd pve-manager: Alexandre Derumier (2): ui: qemu: hardware: add new memory format support ui: qemu : memoryedit: add new max && virtio fields www/manager6/qemu/HardwareView.js | 17 ++++++++-- www/manager6/qemu/MemoryEdit.js | 52 +++++++++++++++++++++++++------ 2 files changed, 58 insertions(+), 11 deletions(-) -- 2.39.2 _______________________________________________ pve-devel mailing list pve-devel@lists.proxmox.com https://lists.proxmox.com/cgi-bin/mailman/listinfo/pve-devel
