  1. [SOLVED] Wer klaut meinen RAM? :-)

    Hallo, der PVE hat 47 GB RAM. ZFS ist auf 18 GB RAM begrenzt. Der VM sind 12 GB RAM zugewiesen. Macht zusammen 30 GB. Wenn ich nun die VM, z.B. durch Kopier-Jobs beanspruche, steigt der RAM-Bedarf des PVE, zumindest kurzzeitig, auf über 90% oder 43 GB an. Jetzt meine Frage: Wer klaut meinen...
  2. 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...

  5. disable RAM overprovisioning

    Is it possible to disable RAM overprovisioning? I'm new to Proxmox. I created and started more VMs that I have physical RAM.

  6. [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...
  7. Memtest86

    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?
  8. Memory problem

  10. [SOLVED] High RAM consumption

    Hello, I'm not sure if this is normal. PVE is reporting almost 50% RAM usage (out of 56 GiB) while all I have running are 2 lxc containers which combined have under 1 GB of RAM allocated. I do have a Windows 10 VM set up but it is stopped and its RAM is from 8 to 24 GB. When I use top to see...
  11. Moving VMs Between Different Hosts

    Hey all, I normally use the host CPU option when setting up VMs (for best performance). This has worked great for me so far. I have recently setup another host server and set them up in a cluster. The new host has different hardware to the previous servers, so now I have Intel and AMD...

    Hello everyone, Basically, I have a SuperMicro 1U with 128GBs of RAM installed. I just installed Proxmox fresh last night on it and it only ever registers 1.83GBs of RAM.

  13. Proxmox not allocating set memory to VMs

    I have this weird issue where all of the VMs that I run, do not get the allocated amount of memory. When rebooting the VM, the correct amount of memory is in fact available in the VM, but after a couple hours, the maximum allowed memory in the VM will be way less. The issue is resolved when I...

  17. Backup RAM overload

    Ich speichere meine Backups täglich auf eine extern eingebundene NAS. Das Problem ist, dass jedes mal, wenn meine Backups gemacht werden meine RAM usage in die Höhe schießt. Normalerweise ist sie bei 30% aber wenn die Backups laufen geht die usage bis auf 80% hoch. Merkwürdigerweise bleibt sie...
