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
