Changing values in qm.container or through drop-ins does not work

[raballew]

In case I set MemoryLimit or MemoryMax to lets say 50% in the qm.container file, reload the daemon and restart the unit and then run podman stats it still showing a limit of 100% of the memory available on the system.

Without any changes:

podman stats
ID            NAME        CPU %       MEM USAGE / LIMIT  MEM %       NET IO          BLOCK IO    PIDS        CPU TIME    AVG CPU %
a25868ed6acc  qm          0.40%       5.37MB / 2.055GB   0.26%       1.726kB / 838B  0B / 0B     5           315.61ms    0.40%

Edit /usr/share/containers/systemd/qm.container:

# MemoryMax
# -----------
# Default is infinity - sets no upper bound on memory usage, allowing the
# service to consume as much memory as the system allows, just like
# MemoryMax=0 or omitting it.
MemoryMax=50%

# MemoryHigh
# -----------
# Default is infinity - Disables the soft memory limit, meaning no throttling
# will occur due to high memory usage, similar to MemoryHigh=0 or
# omitting it.
MemoryHigh=50%
MemorySwapMax=0

Run systemctl daemon-reload and systemctl restart qm.service but this still returns the following:

podman stats
ID            NAME        CPU %       MEM USAGE / LIMIT  MEM %       NET IO          BLOCK IO    PIDS        CPU TIME    AVG CPU %
a25868ed6acc  qm          0.15%       5.37MB / 2.055GB   0.26%       1.866kB / 908B  0B / 0B     5           319.407ms   0.15%

Note that drop-ins do not work either.
