the memory usage bar in the VM summaires in PVE (6.1-3) shows "active"
memory including caches, which is in practice misleading. E.g. this
$ free -m
total used free shared buff/cache
Mem: 7821 4778 177 51 2864
Swap: 3276 123 3153
is shown as using 7.46 GB memory, in red warning color, since this
number exceeds 90% of the available 8 GB. However IMHO the almost 3 GB
memory used as buffer/cache are irrelevant as they will be freed as soon
as they are required by applications. Hence I'd rather see the bar
showing me only 4.8 GB of used memory.
Is that achievable? The guest OS is CentOS 7.x. The qemu gest agent is
