Question about the swap file

[dcspicer]

I recently noticed that under the information page under storage there is a line there for swap file. It reads Swap: -1MB of -1MB used (100%). Meteohub is running under VM. Why is it showing this and is there concern?

I'm not running Meteohub under VM, but I've run other applications in VM environments and seen that for them as well. I suspect it either has something to do with the settings you use when initializing the VM environment, or it might simply be a limitation in the /proc system of VM installations that prevents it from querying data on the host, causing a null value to be reported.
