ram

Moin, gibt es eine Art Formel um den RAM-Verbrauch von Ceph sauber abzufedern? Bei Ceph stand, dass jeder Dienst 1GB RAM benötigen würde, bei OSDs nur 500MB. Wenn ich also mit 4 Journalen (1TB SSD) und 20 OSDs (1TB HDD) unterwegs bin, dann komme ich auf 14GB RAM für CEPH reservieren. Haut das...

I was experimenting with KSM. I wonder if it can work on PVE with lots of LXC containers running same apps. Eg.: lots of apaches. I've enabled ksmtuned with threshold of 50%, it seems to run=1, but pages_shared:0 means it's not sharing and full_scans:0 probably means it didn't even tried to find...

Hi, i installed a windows 10 vm with drivers inside: -viostore -vioserial -netkvm -balloon -qxldod After that i installed qemu agent and spice virt-manager. I give the vm 2 cpu cores and 4g memory. The performance of the vm is ok, but inside the vm, windows shows memory usage 1,5gb and...

I realize this isn't the typical use case. Have Proxmox up and running atop a Debian Stretch install on a very low power\low ram host (Intel Cherry Trail Z8350 processor with 4G RAM). This isn't for production, but mostly a learning environment. Had to do the Proxmox install atop Debian as I had...

Hello, I'm trying to use this monitoring script for Nagios which monitor LXC cpu and ram usage. https://www.claudiokuenzler.com/nagios-plugins/check_lxc.php#CommandDefinition The script uses the command lxc-cgroup I tried lxc-cgroup -n 101 memory.stat which return nothing and no error...

I've a Proxmox system with Virtual Environment 5.2-10 with problem for start a new machine with 16GB ram- kvm: -object memory-backend-ram,id=ram-node0,size=8192M: cannot set up guest memory 'ram-node0': Cannot allocate memory After read message, I've investigated. On Proxmox interface y show...

I've successfully built a Debian 9 host with Proxmox and ZFS. My understanding is that with the availability of resource sharing (e.g., "balloon" memory) it is common to overcommit resources. In other words, on a machine with 64GB, with several VMs running the same OS, I might be able to get...

I was wondering... The HA feature in proxmox ensures that a VM (or LXC) will start on another node in case a node goes down, but the machine will shutdown and will have to reboot on the next node. Would there be any way to ensure that the machine will instantly appear on the other node once its...

Hi everyone, Proxmox allow local RAM/disk overallocation (infinite "virtual" allocation whereas physical host has finite ressources) which is a great tool to optimize use of ressources. But overallocation can be tricky as it represent a risk for the global host (Out Of Memory, No space left on...

Hello, I'm trying to understand how does the webui report the ram usage for the host. As you can see here the ram usage reported by the webui is 50GB but according to free shouldn't that value be "total - available column" (125-45=85GB used) I'm not sure which one to believe. Could ZFS...

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

Hey, I'm new to LXC containers and had a question. When I have a container that's off, why does the container still use all X gb's of ram it's allocated. If it's off, shouldn't it now use the ram. All my charts and netdata show it using it. Thanks.

Hi, we have two node cluster test environment and we have concerns about ram usage which is about 90% on each node. Each node has 64GB RAM and 5 VM consuming abount 24GB of RAM. What consumes the rest?

Hello, We have a weird issue where last night one of our service on our mail server got killed for no apparent reason. Here's the dmesg error: [2018-05-15 19:37:34] Memory cgroup out of memory: Kill process 20766 (sa-learn) score 6 or sacrifice child [2018-05-15 19:37:34] Killed process...

Okay, so before I delve into this, I'd like to point out that the real applications to a concept like this are fairly limited, so please don't just respond with "Why do you need this?" I'll tell you the answer right now: I don't. BUT, someone else might. So if you have even a little bit of...

I've had my Proxmox server for a good few months, and I have a handful (about 6 running 24/7) of full VMs with various hardware stats. Most just have a 1 core processor with 1 or 2 gigabytes of allocated RAM. I noticed today that my RAM usage was higher than normal, about 6.8GB (as reported by...

Hello, my name is Juan Carlos and this is my first time writing into this mailing list. I'm testing Proxmox using an ASUS P6T with 24GB RAM. Currently I have 4KVM using up to 12GB, which means I have 12GB free for ZFS, yet every time I do a VM backup, OS installation or any other workload...

Hello to the community, I'm trying to understand this two parameters that appear on the Web Interface Summary tab on each node. I'm posting this image show both parameters. As you can see my node RAM has used 4.65 GiB and ksmtunned service has consolidated 6.91 GiB. I thought that RAM usage...

Hello, I was wondering if maybe the memory reported in the webUI for LXC containers is wrong. Here's a 'free -m' from a container with 2GB ram and 0 swap total used free shared buff/cache available Mem: 2048 978 9 2757...

Hello everyone, I recently configured Proxmox VE 5.1 as my new hypervisor. Everything works fine, but I can't explain its high SWAP usage. Some more information about the system: root@prxsrv:~# pveversion -v proxmox-ve: 5.1-25 (running kernel: 4.13.4-1-pve) pve-manager: 5.1-35 (running...
