    proxmox is not using available RAM, rather uses (full) swap

    Hello! We are currently using a proxmox-server to virtualize about 20 windows machines (usually 6-8 hosts running concurrently). Currently, we are experiencing an issue with RAM-Allocation. We have 39.62% (24.91 GiB of 62.88 GiB) RAM usage and the SWAP usage is at 98.26% (12.16 GiB of 12.37...

    I set SWAP = 0 on every container I've on Proxmox, but they still use swap for some processes. I can check that from 'top' command. What's wrong?

    Swap sync set to always by default?

    Ever trying to gain just another percent of performance out of an admittedly sub-par setup, I have arrived at the sync parameter of zfs. Digging through some boards told me that disabling sync should be kinda-sorta ok if I trust my power supply, the data on the servers is well backed up and a...

    Swap usage and IP address overview across containers

    LXC container memory configuration

    Could somebody elaborate on how to configure the LXC memory settings properly? The UI allows me to set the memory limit of my container to e.g 1024MB and 0MB for swap. According to the documentation this would be wrong: Is the UI missing a sanity check or am i misinterpreting the documentation?

I stopped/started the VM (to kill the process, rebooting the guest did not reduce swap usage) and swap went back...
