ram

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...

Hi, I have a mv with windows 2022 in pve 7.3-3, a week ago I added a 1TB disk, but the operating system eats all the RAM, when entering the OS I identified that what is eating the memory is a process that tries to deframe the disk I have been adding to the RAM but it always has the same...

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...

Hello! I'm looking for guidance on how to efficiently manage and allocate resources for different users within our Proxmox environment. What are the possible solutions within Proxmox to allocate specific storage, CPU, and RAM resources to individual users, with the goal of limiting their...

hi forum i have very high Ram consumption. What can I do ?

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...

Hello community, Today i did fresh install of Proxmox. While doing first setup I discovered that my system is showing only 11,62GiB RAM as usable from 24Gbit I checked ram with dmidecode -t memory -q and here is result SMBIOS 2.8 present. Handle 0x000F, DMI type 16, 23 bytes Physical Memory...

Hi, we are seeing a really strange behavior on one of our VM. Proxmox () is showing a lot of less RAM ussage for that VM. VM RAM Config (we are not using Ballooning): VM Info: And if we go to the console and show the `free -h`: The VM has installed qemu-guest-agent. The VM OS is: The...

Hello :) I encountered a strange issue today. One of my VM servers had some additions/changes done to it about two weeks ago. Without reduntantly explaining too much, a site with a map was added to a service its running. This new site with the map had been running fine for two weeks, but today...

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...

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...

Hello there, i have a 64gb ram server and have 2 vm running on it one has 50gb allocated other has 6gb allocated. Both devices have ballooning enabled and latest stable virtuo driver installed. But in images i have attached, you can clearly see max 7gb being used but my datacenter dashboard...

On PVE 7.2-3, I created VM (linux Debian) with 4 GB of memory for example (or more), but inside the VM, this is only 915 MB. debian@test:~$ free -mh total used free shared buff/cache available Mem: 915Mi 113Mi 759Mi 0.0Ki...

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...

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?

Hello, first of all, sorry for my English as it is not my native language. I have a problem with some Proxmox servers and memory RAM. The sum of the memory of all the virtual machines diverges a lot from the total of the Proxmox server. All virtual machines have QEMU Guest Agent installed...

Hello, I have some problems with my PVE host and mostly with the RAM management. I attach the screen of my host resources: On this host, I installed one(and only one) VM, that it configured as shown in the following image: The Ballooning is corretly enabled, but I don’t understand why the...

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...

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...
