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...
I have a system using zfs it only has 64 GB of memory in the unit with 241TB of storage, I have 3 windows vm's using 8gb each arc hit ratio at 84% .Proxmox shows a total of 48.11 GiB of 62.57 GiB used (76.89%)
my vm's become extremely sluggish during a resilver so much so that we can't log in...
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 /...
Hello there lovely people.
So, as the title says, Memory Performance is really bad. I tried to debug this since 3 or 4 Weeks now and I´m all out of Ideas. In a Linux VM i get around 24GB/s with 1M BS which is around the maximum my Board/System can handle. I used the Phoronix Test Suite as a...
My summary of virtual machine Memeory Usage is not correct by all linux servers.
For my windows vm's i have installed the virtio drivers en the guest agent en they memory usage is perfect the same as in task manager.
Only how do i set this in debian and centos servers? I have installed...
I have a hyperconverged setup with 3 nodes. All running Debian 10, same hardware. There appears to be a memory leak on all the nodes that I could use help tracking down. Here's some pertinent information
proxmox-ve: 6.3-1 (running kernel: 5.4.78-2-pve)
I'm trying to create a new VM on one of our nodes but I'm getting an error when clicking "Finish."
Parameter verification failed. (400)
memory: value must have a minimum value of 16
Searching the forums and the web didn't give me anything useful, so I've resorted to...
I am currently looking to use proxmox for my cluster but i have some consernes..
can i put all the cpu power, memory power on a single pool so for exemple i can use 4core on one node and 2core on an other node and for memory i use 4GB on 1 node and 1GB on an other node. is it something...
Hi, have a strange problem with one PVE (V. 6.1) host and its Debian 8 (old version for technical reasons) Guest. The guest crashes every now and then with no apparent reason, sometimes runs fine for weeks. The PVE logs say out_of_memory :

Hallo liebe Proxmox Community!
Ich beobachte seit Längerem ein Problem mit LXCs bei Proxmox. Nach ein paar Tagen unterscheidet sich der Speicherverbrauch laut ps_mem (welches den Speicherverbrauch der einzelnen Prozesse in der VM addiert) und der zur Verfügung stehende Speicher laut free...
I installed my proxmox server on a two 250 gb ssd with raid1. My vms are stored on another zfs storage pool. The box has 64 gb memory. My memory usage is constantly past 90% despite having a few containers and vms setup with about 30 gb usage between all of them.
I am having to do this daily...
We are trying to debug some memory issues with a container and best practices to monitor
Within the PVE interface I see

inside the container:
MemTotal: 8388608 kB
MemFree: 2967096 kB

I'm having a issues regarding the ram usage on our hypervisors. It seems there is ram going I don't know where.
The hypervisor has 70GB of usable total ram. The current arc usage is 9GB according to arc_summary. I've calculated the amount of ram used by each LXC containers on the host...
Hey. I noticed a strange one. Added 8 GB of RAM to the virtual machine. And inside she sees only 7.8 GB. What could be the problem? Virtual Machine is Ubuntu 16.04
Hi; I saw few post on this in the past but no answer make really sense.
Here Proxmox tell me my OpenMediaVault use more than 90% of the allocated memory (independently how much I give to this VM) but in reality OMV only use 5%.
There is a way to fix that ?
I have a (possibly unrelated) problem where one cluster member's TOTEM keep generateing retransmits from other nodes or local timeouts. When I checked nodeC kept joining and leaving the cluster, about 50 per seconds. Restarting corosync resulted the same.
It turned out however that on other...
I've been having an issue on one of my proxmox servers lately, but I've been unable to recreate this on my other server:
I run a set of Ubuntu 18.04 LTS Server VMs. When I launch VNC to access the VM shell after some time running, I encounter a spam of this error:
