Hello Proxmox Community,
I hope you're all doing well. I'm currently exploring the functionalities of Kernel Same-page Merging (KSM) in conjunction with AMD's Secure Encrypted Virtualization (SEV) and Secure Memory Encryption (SME) features. Specifically, I'm keen to understand the interplay...
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!
Thank you for the superior product!
I have just upgraded the cluster from version 5.2 to the version 5.3 .
I noticed, that KSM sharing seemed not to work any more - on the dashboard in the Summary I saw always "
KSM sharing 0 B".
As I migrated form version 4.4 to 5.2 I experienced...
Hi
I migrated VMs from 4.4 to 5.2.
These VMs used KSM but now the KSM usage is 0 or minimal.
Which memory setting that when the system allow use KSM?
Thanks
I noticed that I have the ability to download ksmtuned from the apt repo (it says that it is not installed on all 3 of my nodes) and that it plays a large part in balancing memory usage between VMs, but it also seems like I have config files for KSM and that ballooning/memory sharing is working...
I am running the very latest updates of Proxmox 5.1 and the server does have KSM enabled, I had a VM kernel dump on me, and I noticed in the logs I am getting "page allocation failure" messages. Overall the RAM usage seems to be OK and the server is only running about 35 VMs each with 4GB of...
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
Have anyone else noticed 'lazyness' in KSM with kernel pve 4.13.13-5.
May patches for Meltdown and Spectre have any impact for this?
Before we could share up to 2TB of memory in our test cluster. Now the sharing is very slow and it can share only about 100GB in whole cluster. Cluster...
Hi! I have Proxmox VE 3.4-3 with kernel 2.6.32-37-pve. My server runs several OpenVZ containers together with KVM virtual machines.
At the moment cat /sys/kernel/mm/ksm/pages_sharing returns 0 and that's fine because my RAM usage is under 80% and KSM_THRES_COEF=20 in /etc/ksmtuned.conf.
My...
Long time lurker on this forum, first time poster. I have read many many threads that are a close variation to, but not exactly similar to my issue. And I have already resolved my issue to my satisfaction, but have some questions about how Proxmox's deeper features work and if I should really be...
