Hello!
We are currently using a proxmox-server to virtualize about 20 windows machines (usually 6-8 hosts running concurrently).
Currently, we are experiencing an issue with RAM-Allocation.
We have 39.62% (24.91 GiB of 62.88 GiB) RAM usage and the SWAP usage is at 98.26% (12.16 GiB of 12.37...
Hi all
I've got 3 x Windows Server 2012R2 VM with the following memory config:
Min memory: 6144 MB
Memory: 24576 MB
My physical machine has 64 GB RAM.
I've enabled ballooning, installed QEMU agent, installed the balloon service and driver on each VM.
One VM uses around 2.63 GB RAM idle which...
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...
Hello,
The balloon memory behavior in version 5.3 changed compared to 5.1. And not for good.
I have a VM with a memory configuration like this:
min memory 448mb
max memory 16gb
In Proxmox VE 5.1, the host provided memory to the guest machine as it was needed. Usually, it had 3gb, and when a...
Good Morning.
I implemented a Proxmox server for testing in a company that provides consulting, what happens is:
Server has 16gb RAM.
Only Server 2016 x64 is currently installed.
I can not work with 2 concurrent users in RDP and I have not been able to figure out what happens to the memory...
Hello,
I've got a PVE cluster running Ceph and found out that a node, left alone without VM, will steadily use more RAM over time:
This is a concern since my total available memory isn't infinite ;)
I can reboot to solve the problem but it suppose that seems a bit Micro$ofty...
I could...
I've a Proxmox system with Virtual Environment 5.2-10 with problem for start a new machine with 16GB ram-

After read message, I've investigated.

I am doing my daily rounds (lol it sounds very official) and I noticed that my web interface was not responsive, I thought it was my laptop, it does that from time to time when I go from one place to the other, my firewall sometimes blocks me. So I rebooted my laptop and tried again, still the...
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...
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...
