memory

Hi, everyone I have a problem with the use of memory in my proxmox. The memory consumption is increasing while a backup task is in progress, and when finalize the backup job, remains high. I run only 3 containers and no VM in this server (is a Lenovo ST550). Kernel Version Linux 4.15.18-7-pve...

Hello, I'm seeing when I write a large file within a VM linux, I'm also filing up the VM systems memory. This memory is released when I delete the file. dd if=/dev/zero of=test1.img bs=512k count=1000000 Is this normal? Cheers

Hi, I use Proxmox version '5.1-38'. I've 30 containers and VM-s. I want to change swappiness variable from 60 to 15 on several containers and it says 'sysctl: setting key "vm.swappiness": Read-only file system'. I think I should to change this on node but I don't want. Can I change it on only...

I have seen a suspicious behavior of my GPU-passthrough VM (Linux) for quite some time. That is no matter how small the actual memory usage is (even when the ballooning is enabled), upon starting the VM, it will "try" to allocate the full memory (as configured). This doesn't mean that ballooning...

Hi guys! I have a cluster with proxmox, how I can see, which VMs use memory (RAM) on one node. command or something else...

I need to virtualize several dozen Windows 10 Pro boxes, does anybody know if the Virtio drivers do work and also how does the memory sharing works? I need to show 16G RAM per box, but naturally, I want to use only what is needed so I may overcommit.

Hi, I have a personal Proxmox environment I use for testing, for it I use the community repo which is running the latest version of proxmox VE (5.2-2). Full package version list: proxmox-ve: 5.2-2 (running kernel: 4.15.17-1-pve) pve-manager: 5.2-1 (running version: 5.2-1/0fcd7879)...

Hi, I am using a pfSense 2.4 (FreeBSD based) virtual machine on KVM and I see a different RAM usage in Proxmox than in the VM itself. Proxmox shows more than 90% of RAM usage (~ 15Gb of 16 Gb): but both pfSense and FreeBSD are showing only 2% of usage: But the virtual machine is giving...

I am investigating 2 incidents that seem to be similar. On 2 different PVE servers, both running ZFS with raidz (mirroring with 2 disks), I experience random reboots during backups of KVM machines. (no clustering, single hosts) Both server are low on RAM. One has 8 GB RAM and a single VM with 1...

Hello there, I have two questions. When VM is starting, is there some way to allocate full memory which is assigned to VM on node? If not, is there any option to disable memory overcommitment? I'd be very grateful for any response. Thank you!

Hello I would like to ask you for some help. I've a weird situation. Every few hours I can't restart my VM because of: root@s0:/home/xarion# qm stop 128 root@s0:/home/xarion# qm start 128 ioctl(KVM_CREATE_VM) failed: 12 Cannot allocate memory failed to initialize KVM: Cannot allocate memory...

Hello, It's seems the shared memory from an LXC container shows the shared memory from the host. Here's the host: total used free shared buffers cached Mem: 64414 62599 1815 1833 9329 31029 -/+ buffers/cache: 22241...

Hi, I am new to Proxmox and am using it on a small homelab system. It is running on a fanless mini PC with only 8GB of RAM. I am a Linux user and so I am currently hosting virtual Linux environments running in containers. So I am trying to understand how memory is managed. So let's assume I...

Hi folks, Just after a sanity check here. I recently upgraded my Proxmox 5.x server to 5.1 and noticed the following errors on boot. [ 0.000000] [Firmware Bug]: TSC_DEADLINE disabled due to Errata; please update microcode to uersion: 0x3a (or later) Reading all physical volumes. This may...

Hello, I've recently changed the swappiness on my host to 0 since there is plenty of ram available. Rebooted to apply the change. Now my container still consume swap even when there is memory free. Here's in the webui: Here's the free output inside the container: total...

Hello, After rolling back a snapshot on an LXC containers the pvestatd service completly freaked out and started spitting alot of errors regarding this container Nov 24 10:35:59 dev-proxmox-1 pvestatd[16792]: lxc status update error: can't open '/sys/fs/cgroup/memory/lxc/143/ns/memory.stat' -...

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?

Originally posted this in IRC and was suggested I post here. I have a proxmox host running 4.4.67-1-pve which is using 99% of it's swap. Yesterday it was one vm using ~25G of swap. I stopped/started the VM (to kill the process, rebooting the guest did not reduce swap usage) and swap went back...

Hello, In proxmox 4, the use of the memory for a vm is wrong. On the line memory use proxmox displays 90% while in the vm (windows 10) there is only 15% of used: 8 go of allocated - 1.5 used in windows. Is this normal? thanks

Hi guys, Experiencing the same issue on 2 separate clusters of different sizes in two different locations with completely different hardware. Issue is that after a week or two of regular cluster operation memory usage by corosync grows to crazy levels for instance currently on a node it's at...
