memory

Hi, We had recently a node that restarted suddenly without any warnings. The machine was running pretty capped RAM wise. I downloaded the logs from the node in question but i don't see any trace in them. all i see is the start phase, nothing interesting before Can you lead me to a log file...

Hi, I have some Ubuntu 22.04 VMs with qemu-guest agent installed and I've notice that the memory usage shown in the GUI is completely different from memory stats within the Ubuntu guest OS. Is it a problem of the guest agent? Does it computes memory usage as (used+buff/cache)/total instead of...

Hello everyone, I'm not used to the forum and it's rules so very sorry if make a mistake or if my thread is not at it's right place... So I have an issue with a little pve host that is actually a sort of mini network oriented computer with 4NICs and the following CPU : 4 x Intel(R) Celeron(R)...

Saw a mini PC with a Ryzen 7 3700U. I know that this processor is outdated, may this device consider small power consumption but big processing power? My main purpose is to install OpenWRT on the Proxmox as a Internet router. May simply learn docker, container and linux, use the virtual machine...

Hi, We are experiencing an issue that one of the VM (windows server) in our Proxmox cluster keeps stopping at regular intervals. We have checked the Syslog for OOM messages 'cat /var/log/syslog | grep OOM'. But does not get any output. On checking the summary in the Proxmox interface, we could...

Hi I imagine some VPS hosting companies have ways to sell more memory than their servers actually have. How do they do this? Any advice for making the most of your server memory? A few ideas so far: * Use containers rather than VMs - pretty obvious * Make sure KSM (Kernel Samepage Merging) is...

Hi, I have deployed a Win10 Vm on a 64 GB Ram node and have allocated it 32 gb. After installing the Balloon Drivers the VM shows correct memory usage but the node summary still shows the incorrect usage , no zfs used and cache/buffer is at 3700k only. I have tried old virtio drivers too . How...

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...

Hello everyone! I've been using Proxmox on NUC's for a while now and recently purchased a new ASRock NUC Box 1165G7 then installed Proxmox 7.1 as a ZFS mirror on two internal disks (Sata SSD and NVMe M.2). I started experiencing odd things where pings and the Proxmox UI would stop responding...

Hello! I have a windows server 2016 vm in proxmox, with 16gb of memory, installed the ballooning service which is running, but the used memory displayed by proxmox is very high (about 12gb), but in the task manager the used memory is only 3gb. Nothing happens if I stop or restart the ballooning...

Hey, I have a few VMs running Ubuntu. When I log-in using SSH, then the VMs tell me this info: So the memory usage (from Ubuntu's perspective) is around 11%. Now when I look at the VM overview of Proxmox, I see this: So Proxmox is telling me that the memory usage of the databases VM is...

Hello, This had been asked several times however after extensive search there is still no real answer that would make sense or a formula that I was able to follow to assign memory - sometime it work and sometimes doesn't (guessing!) up to 48GB works fine after adding this workaround "options...

Hello there! Recent changes: i have recently migrated my boot device on my proxmox server to two Seagate Iron Wolf M.2 SSD's - which are running in a raid1 configuration for failover. After setting up proxmox i started migrating all my VM's to it, thats where i noticed something weird. Proxmox...

Good day all, In the process of upgrading a pve 5 cluster to pve 6 (better late than never). After the corosync upgrade to 3 with all cluster nodes still on pve 5 and online with quorum there was a netwok issue on one of the nodes. All VMs became unreachable for a minute or two and then came...

Hi there, We've been migrating away from our ESXI cluster to Proxmox, and it has been great so far, but I am still wondering about the memory saving features such as KSM and ballooning. Are KSM and Ballooning both enabled at the same time once the 80% limit has been reached? Will KSM /...
