    [SOLVED] Proxmox - RAM usage

    How much in theory PVE 8 requires RAM for its own usage? It runs on 1 TB SSD with ZFS. If I remember it correctly, the rule of thumb says: 1TB of storage equals to 1GB of RAM usage for ZFS based system... I have on server with 32 GB of RAM and mentioned above drive installed Proxmox 8 with 3x...

    Wrong memory usage reported in Proxmox interface even with ballooning off?

    Hi all, one of the problems I am trying to get to the bottom to is, Proxmox thinks my OPNsense VM is using 6 gigs of RAM when it's only using 400mb or something? I first simply assumed this would be something to do with ballooning feature, and working as intended if that were desired - but it's...

    Proxmox memory bar separated by type

    Hello! Is there any way to make memory bars colored by type of data that's stored in it? I mean, currently it shows you almost 100% of RAM if you use half of RAM by VM's and other half is ZFS cache. My point is to separate bar into multiple colors to make it clear what is cached and what's not...

    Ballooning Ram acting weird

    Whenever I allocate minimum memory to a vm the vm starts to consume all of its ram even when idle but when i check host the host is freeing up ram so ballooning works normal. But the problem is with vm, that when it consumes 98% of ram i cant carry out any work in it since apps crash due to no...

    Is it possible to disable RAM overprovisioning? I'm new to Proxmox. I created and started more VMs that I have physical RAM. I'm familiar with ballooning and the VMs have the ballooning driver installed in the guest, but the startup of the VMs happened too quickly so a VM that was running for...

    [SOLVED] [HELP] PVE can not detect all the ram (128G RAM only detects 64GB)

    Hi, everyone. I got an incomprehensible problem in using PVE. My server has installed 8*16 128G RAM, I am confident that the RAM is not broken and that it is correctly inserted. Because both the bios and the BMC can recognize 128G RAM. However, PvE cannot identify 128GB RAM and can only detect...

    I need to launch Memtest86+ at startup of my Proxmox machine. I manage to add it to Grub, but then I don't know how to add it to systemd-boot. I do "proxmox-boot-tool refresh" and only available kernels are added, not Memtest86+. Any ideas?
