high level description: VM/CT vmstatus returns new fields for configured and running "usage" values, these are then broadcasted by pvestatd on each node via KV.
helpers in guest-common to check those limits pool API returns limits and usage, them and allows setting the limits qemu-server/pve-container try to check actions against those limits. since the broadcast is async, there is always an opportunity to cheat by racing against the broadcast. this is unavoidable unless we want to serialize all usage affecting tasks across the cluster.. TODOs (but sent this anyway to get feedback for the basic concept): - disk limits/usage - fill in missing edge cases (I am sure there are some) - RRD/metrics support (or even switching entirely to RRD based broadcasting instead of KV) - timeout of broadcasted data if node goes offline/stops broadcasting - actual GUI - ... ? I haven't tested the pve-container changes much, there might be missing parts and dragons there, although it mostly follows the qemu-server changes. interdependencies: - pve-guest-common needs pve-access-control - pve-manager needs pve-access-control and pve-guest-common - qemu-server/pve-container need pve-guest-common pve-access-control: Fabian Grünbichler (1): pools: define resource limits src/PVE/AccessControl.pm | 42 +++++++++++++++++++++++++++++++++++++-- src/test/parser_writer.pl | 14 ++++++------- 2 files changed, 47 insertions(+), 9 deletions(-) pve-guest-common: Fabian Grünbichler (1): helpers: add pool limit/usage helpers src/PVE/GuestHelpers.pm | 190 ++++++++++++++++++++++++++++++++++++++++ 1 file changed, 190 insertions(+) pve-manager: Fabian Grünbichler (4): api: pools: add limits management pvestatd: collect and broadcast pool usage api: return pool usage when queried ui: add pool limits and usage PVE/API2/Pool.pm | 51 +++++++++++++++++++++++++--- PVE/Service/pvestatd.pm | 59 ++++++++++++++++++++++++++++++--- www/manager6/pool/StatusView.js | 33 ++++++++++++++++++ 3 files changed, 135 insertions(+), 8 deletions(-) pve-container: Fabian Grünbichler (7): config: add pool usage helper status: add pool usage fields create/restore/clone: handle pool limits start: handle pool limits hotplug: handle pool limits rollback: handle pool limits update: handle pool limits src/PVE/API2/LXC.pm | 25 +++++++++++++++++++ src/PVE/API2/LXC/Config.pm | 21 ++++++++++++++++ src/PVE/API2/LXC/Snapshot.pm | 7 ++++++ src/PVE/LXC.pm | 37 +++++++++++++++++++++++++++ src/PVE/LXC/Config.pm | 48 ++++++++++++++++++++++++++++++++++++ 5 files changed, 138 insertions(+) qemu-server: Fabian Grünbichler (6): config: add pool usage helper vmstatus: add usage values for pool limits create/restore/clone: handle pool limits update/hotplug: handle pool limits start: handle pool limits rollback: handle pool limits PVE/API2/Qemu.pm | 54 ++++++++++++++++++++++++++++++++++++++++ PVE/QemuConfig.pm | 30 ++++++++++++++++++++++ PVE/QemuServer.pm | 49 ++++++++++++++++++++++++++++++++++++ PVE/QemuServer/Memory.pm | 6 +++++ 4 files changed, 139 insertions(+) -- 2.39.2 _______________________________________________ pve-devel mailing list pve-devel@lists.proxmox.com https://lists.proxmox.com/cgi-bin/mailman/listinfo/pve-devel
