I have two VMs set up in our test bed, one was created by cloning of the other. Both are running pfSense, so are set as "other FreeBSD." PVA shows dramatically more memory usage than the VM shows. With 1 GB of RAM per VM (2 MB video RAM), the vast majority of the time I've looked I see something like: PVA shows: 650 MB used out of 1 GB pfSense's web interface shows: 14% of 989 MB used "top" (run inside the VM) shows: 17M active, 71M inactive, 105M wired, 769M free The resource graph in PVA has occasional steep dips but is usually at the higher level. How does PVA calculate memory usage? I realize that without an agent installed it would likely be less accurate but if it shows a number I wouldn't think it would show an inaccurate one...?
