The `ps` from the Debian Bookworm version of the `procps` package does report
it here if I use something like `ps -C kvm -o pss` though, FWICT

FWIW, depending on how the sum is used it might actually make even more
sense to use PSS, i.e., the proportional set size which better accounts
for shared memory by dividing that part between all its users, as if
e.g. 10 QEMU processes have 100 MB of shared code and what not

total does not require the printf fix because it does not do any
calculation.
The "print $2"

oh, and shouldn't we also add that to total and free_memory calculation,
even chances are less that the limit is hit there ?
total=`awk '/^MemTotal:/ {print $2}' /proc/meminfo`

Hi Stefan,
looks good for me so far and indeed, on very large system when VMs eat
up >2TB this could hit the limit very soon.
but shouldn't we add some newline , as the original "print sum" prints one ?
root@s740:/usr/sbin# seq 1 10 | awk '{ sum += $1 }; END { print

No reason, but even if this looks pretty straight forward, positive
feedback would

hi,
any reason why this did not get a response ? (i do not see rejection of
this ,nor did it appear in
https://git.proxmox.com/?p=ksm-control-daemon.git;a=summary )
and, while we are at ksmtuned, i think it's is broken, especially when
run on ZFS based installations, as
awk internally uses float for every calculation, printing a large float
with awk results in 1.233e+09 format which causes the script to fail afterwards.
Instead I am printing the float without decimals.
