4G RAM qemu-kvm
Test case: boot the image, wait 5 minutes (there is a settle period
during which services are still doing things and memory usage isn't
stable), launch Terminal and run 'free -m', launch System Monitor and
read Memory value.
**Fedora 32 workstation live**
$ free -m
total used free shared buff/cache available
Mem: 3922 617 1685 11 1620 2987
Swap: 0 0 0
System monitor: 950 MiB
**Fedora 33 workstation live**
$ free -m
total used free shared buff/cache available
Mem: 3922 619 1902 11 1400 2997
Swap: 1960 0 1960
System monitor: 941 MiB
Weird that 'free -m' shows used is 2M more for F33, but System monitor
shows 9M less. And also the ~320M difference between the two tools'
report for memory in-use. The amount of installed memory (the total)
does affect these. I'm not sure why.
But that's a hermetically sealed setup. I suspect PackageKit. I've
seen it take upwards of 15% RAM in some cases. Currently on my laptop
it's taking up nearly 1G on its own
25Kb 36Kb CPU% MEM% VIRT RES

0.0 11.9 1.44G 932M
2112 root 2:19 3 0 S ? ? /usr/libexec/packagekitd
After 'systemctl restart packagekit' and waiting 5 minutes for it to
settle, it's only taking up 24M. Does this suggest a memory leak?
