    Watchdog Reboots

    ...are allowed to use. Our backup for this hosts starts at 2am, but at 3:05 when starting to backup an RDS host on this machine, memory usage goes crazy, Around 3:20 it started killing VM's one after another, till the watchdog gave up and rebooted the whole host. Last night, this also...

    [SOLVED] Docker inside LXC (net.ipv4.ip_unprivileged_port_start error)

    For me it's not so much about RAM as it's about Disk Space. RAM wise I agree that with Dynamic Memory Management (VM Memory using Balloon Feature) it works already much better. I use podman (rootless) instead of docker. As a Reference Point, although of course that's highly subjective, I have...

    Memory leak in 4.0.14

    No, its till an issue. It has not affected performance so I have come to the realization that it uses 80 to 95 precent of RAM on the VM What i have noticed is that when rebooted the RAM usage is normal (600MB) but when a backup is preformed on one of my VMs/LXCs then they RAM goes back to being...

    Memory leak in 4.0.14

    Did you ever figure this out or did they fix it in an update after this? I was having a similar memory leak issue after reinstalling Proxmox Backup Server with version 4. I didn’t have this issue with version 3. Started doing this immediately after migrating to a fresh version 4 VM. Nothing has...

    Hello, on some training-vms I upgraded to PVE 9.1.6 and Im having some weird issues atm I cant track down. Im not sure if it is related to the 9.1.6 upgrade. * Ceph -> OSD -> Global-Flags: Ceph Global Flags Show Integers "0" or "1" instead of Checkbox ** this makes it hard to use and multiple...

    Windows Server 2025 VM constantly 50%+ CPU and feels laggy on SSD storage (other VMs fine)

    ...to 12288 MiB. The problem is that Windows Server 2025 VM constantly shows around 50–60% CPU usage in Proxmox, even when mostly idle. Memory usage is fine (around 30%). Inside Windows: Initially saw TiWorker and Windows Modules Installer Worker high CPU (expected after install). System...

    Re: Windows VM Memory Full Issues (Driver locked RAM)

    Hello! Maybe someone will find my situation helpful. I was setting up a virtual machine on TrueNAS (Server 2019 Standard) and got a memory leak error when using the virtio-win-0.1.266.iso drivers (for example). The RAM usage by the block lock driver increased to 93-96%, no matter how much RAM I...

    [SOLVED] PVE 9.1.5: Linux VM Freeze Randomly

    Hello together, currnetly I'm running PVE version 9.1.5 on two HPE DL360 G10 as a two node cluster without HA. On host #1 I installed two VMs (IPfire 2.29 U199, Linux Kernel 6.12.58-ipfire #1 SMP PREEMPT_DYNAMIC) for testing an development and also one LXC and two other Linux (openSuSE 15.6)...

    Nach Upgrade von 8.4 auf 9.1.4 und 9.1.5 falsche RAM-Auslastungs Anzeige bei einzelnen Windows VMs

    Grundsätzlich ist eine Auslastung über 100% möglich, da nun seit Proxmox VE 9.0 auch die Host Memory Usage hinzugerechnet wird, was besonders bei VMs ohne Ballooning bedeutet, dass das konfigurierte, maximale Memory Assignment überschritten werden kann. Siehe dazu [0]. Läuft auf dem Windows...

    RAM Usage Discrepancy

    Both. PVE also counts cache. Htop shows this as yellow but it's hard to see/interpret. See free -h and google something like proxmox memory usage. There's decade old discussions about this.

    [SOLVED] Over 100% CPU Usage with one idle VM running in Proxmox 9.1.5

    Your cpupower frequency-info output on the R740 is the key here: no or unknown cpufreq driver is active on this CPU Your working R730 has intel_cpufreq with the performance governor. The R740 has no frequency scaling driver at all. So the Xeon Silver 4214s are probably stuck at base clock (2.2...

    [SOLVED] Over 100% CPU Usage with one idle VM running in Proxmox 9.1.5

    Hi there, I have 2 servers hosting proxmox 9.1.5. They are independent. One is an older R730 with spinning HDDs, and the other is a newer R740 with SSDs. Config info below. I am doing some testing as I've just installed the R740, and I am running a single debian plasma VM on each. The R730...

    Live migration from LVM to LVM thin without dataloss?

    BTW, ZFS with refreservation=none is the more feature-rich option: you get thin provisioning plus native checksums, self-healing (with RAID-Z), built-in compression (lz4), and very efficient copy-on-write snapshots at no extra cost. The downside is RAM usage, since ZFS ARC can consume a...

    [SOLVED] Wrong memory usage monitoring

    I was just searching for a solution to warnings I get about high memory usage. I understand your explanations, but I was wondering if you could make this configurable. The situation now makes total sense if you look at it from a hypervisior perspective. It may change if you look at it if you...

    How to set Swappiness permanent to 0 on Proxmox 9

    In my exhaustive testing over the decades, both Windows and Linux does not reliably swap _out_ data back into RAM. This is one of the important details why I not only monitor for any usage of swap at all on anything I care about (and alert if enough swap is used, >10%), I also have periodic swap...

    How to set Swappiness permanent to 0 on Proxmox 9

    What I don't see mentioned here is that just monitoring the swap usage is not as good as monitoring the swap in AND swap out activity. You want to monitor that, because if you only swap in stuff without reading it back soon, that is actually already not important. A lot of swap in / swap out...

    How to set Swappiness permanent to 0 on Proxmox 9

    There are lots of reasons you don't want to use swap day to day, and that it should be used as a last-resort available resource. I actually wrote an article on the matter: https://it.lanified.com/Articles/Youre-Using-Swap-Memory-Incorrectly But in the case of a PVE node, the fact is that all...
