Proxmox Lite

I am using proxmox without cluster, zfs etc in standalone mode. I installed it on debain and by default install it takes near about 900 MB ram. Now I stop below services which I do not use

systemctl stop pve-daily-update pve-ha-crm pve-ha-lrm pve-firewall pvefw-logger corosync spiceproxy pvesr.timer pve-daily-update.timer

systemctl stop zfs-mount.service zfs-share.service zfs-volume-wait.service zfs-zed.service zfs-import.target zfs-volumes.target zfs.target ceph-fuse.target ceph.target

And now memory is 475MB and still gui works. Now if I stop web interface by

systemctl stop pveproxy pvedaemon pvebanner

then memory usage is 200 MB. But I want web interface so I enabled above. But when I check in top I have three process for pveproxy & pvedaemon workers. Can I change this worker setting to 1 to reduce further memory usage.

Thanks in advance if some one know this config location or any other option to further slim down proxmox for standalone usage.

  • Have you tried systemctl disable for the unwanted services?

    Yes, once system is stable then I disabled by below command

    sudo systemctl disable pve-daily-update pve-ha-crm pve-ha-lrm pve-firewall pvefw-logger corosync spiceproxy pvesr.timer pve-daily-update.timer

    sudo systemctl disable zfs-mount.service zfs-share.service zfs-volume-wait.service zfs-zed.service zfs-import.target zfs-volumes.target zfs.target ceph-fuse.target ceph.target

    Well, usually running KVM or Proxmox on nodes less than 8GB makes no sense.
    And if you have more, you likely wont give a fuck about that 900MB.

    If you really go that low, I would skip KVM and try LXC/LXD.
    Which as nearly zero memory usage alone.

    LXD does support KVM as far as I know, so may try that.

    I like proxmox web interface even for LXC/LXD. Is there any option to disable KVM in proxmox in case if I do not need it to check how low memory usage goes. I am able to reduce workers to one by editing below files

    sudo nano /usr/share/perl5/PVE/Service/pveproxy.pm
    sudo nano /usr/share/perl5/PVE/Service/pvedaemon.pm

    And change max_workers => 1. And now memory usage is 425 MB

    Bookmarked, to remind me to review my three Proxmox instances - 2x8Gb, 1x16GB. ;)
    I had a 4GB one but installed OpenNebula on it - probably revert though.

  • Why not use docker with portainer?

    He wants to reduce his memory usage and you come around with Docker to add more memory.....

    Well, I did modifications in the code also, to disable some shit, which was listen on all ports for no reason. Still iptables would be easier.

    Could work though but you need to make sure to run your updates again after an proxmox update or reverse it if it breaks and put it back afterwards.

    Isn't docker is supposed to have almost zero overhead ?
