  1. Как решить, что виртуалка больше не нужна

    Речь пойдёт про VDI-портал: систему, которая клонирует виртуалки из шаблона, выдаёт их пользователям и гасит простаивающие. Но статья не о нём как о продукте, а об одном вопросе, который на входе выглядит тривиальным: этой машиной ещё пользуются? Ссылка на код будет в конце, одна. Нужен был пул виртуалок под технический отдел. Много. Держать их все включёнными не на чем: одновременно работает хорошо если четверть, а ресурсы гипервизора кончаются сразу и у всех. Первое решение было очевидным — скрипт по таймауту. Никто не подключён N минут — машина гасится. Понадобилась — поднимается. Скрипт я написал за вечер, и он даже работал, но по итогу я изобрёл VDI. Только не так, что посмотрел готовые решения и они меня не устроили, — я вообще не формулировал свою задачу как «нужен VDI» и потому не искал. Я решал «пусть виртуалки сами гасятся», а всё остальное наросло само, вопрос за вопросом. Когда стало очевидно, во что это превратилось, переезжать на готовое было уже и поздно, и незачем. Дальше разбираю вопросы, которые нарастали.

  2. The big problem I have with #Proxmox is that volumes are stand-alone objects: it just has mount points on containers.

    This bothers me because I want to do OCI on LXC, and upgrades mean recreating the LXC.

    On Incus, you can do this naively and safely because networks and volumes and stuff are stand-alone objects, so you can create and delete in whatever order.

    On Proxmox, you have a specific sequence so resources get migrated without losing data or state. Fuck it up, and you deleted your data.

  4. Diagnosing Proxmox ZFS latency? Use zpool iostat for real-time per-vdev IOPS/bandwidth, then zdb -C for pool config and deeper structural insight. Pair with arclist to spot ARC pressure. Practical commands for ZFS 2.x on PVE 7/8. #proxmox #snippet #zfs-performance #zpool-iostat #ValtersIT

  5. I get 900/100 service from my ISP, Zen, but that's irrelevant, as we're dealing with the layer 2 connection between the proxmox NIC and the ONT.

    If I force the link speed on the proxmox NIC to speed=2500 I get an error about the driver not supporting forced settings, and the link goes down. It only comes back up if I set it to auto again.

    Like I say, I'm only on a 900/100 package from Zen, but I'd still expect the NIC and ONT to negotiate a 2.5Gb/s link 🤔

  7. Question for anyone out there running a combination of #OPNsense (26.7.1) as a guest on #proxmox (9.2.10) with #openreach fibre:

    Does your external NIC negotiate 2.5Gb/s with the openreach ONT?

    Mine only negotiates 1Gb/s, even though it's an Intel I225-V (rev 3) NIC that is 2.5GbE capable, as is the ONT.

    The NIC is not passed through to the OPNsense guest, it's on a Linux bridge in proxmox with the guest given a virtual NIC on the bridge. OPNsense sees the vnic as 10Gb/s

  10. @adr If Proxmox counts as "just container it", that's a great solution. HaOS thinks it's managing the system, but still all advantages of having it containered.

    I'm running it happily that way since a year or so

  12. New post: Last night my docker containers did not come back after a scheduled host reboot. I don't know why.

    I'm hoping this script should prevent this from recurring though:

    If anyone got a good theory on why this happened, I'd love to know.

  14. 🚀 Deploy a virtual load balancer on Proxmox VE.

    Our latest technical guide covers the complete journey — from VM creation and networking to 2-node HA, security, SSL/TLS, testing and monitoring.

  15. After coming close to running out of resources last week and having to re-purpose another device turning it into a 3rd Proxmox node, got me thinking....

    So, I built a basic tool for rough guidance.

    It calculates vCPU overcommit ratios and RAM allocation locally in your browser. Just pure client-side math so you don't accidentally OOM your hypervisor like I almost did.

    Have a play with it here: https://unknownuniverse.uk/tools/proxmox-calculator.

    More tools coming soon!

  23. Very strange. One of my #Proxmox cluster nodes managed to temporarily break itself because the ownership of `/var/log/pveproxy/access.log` was changed to root:root after a reboot. Easy to fix, but strange.

    Also not sure why the node rebooted, could be a watchdog timeout, perhaps caused by one of the NICs being an Intel I219. I've not seen any issues with that NIC on any of the nodes (all are the same hardware) so offloading is still enabled.

  30. I've been trying to diagnose intermittent dropped packets, high latency, and WAN disconnects on a DSL connection at a remote site for months. The ISP has had many techs come out and try to fix it on their end.

    Today I ran some tests with disabling different equipment at the site to try and narrow down if something is inducing these issues upstream of the router.

    It seems like perhaps the #proxmox server or VMs or LXCs, the KVM dongle for remote access, the TrippLite PDU, or the five port switch all of that is plugged into might be to blame.

    However, this has been an intermittent problem so I'm not entirely convinced that I've isolated the problem. It could just be that when I was testing it was acting up in a specific way.

    I'm not physically at the site and my local support can't physically get to where the switch is (on top of a high cabinet) so I can't easily disconnect individual devices and the switch, while it has a management interface, is not the easiest to figure out what is plugged into what port.

    I think what I can do is move Pulse and Uptime Kuma LXCs to operate locally at the site rather than remotely. That'll take off some network traffic (the site is bridged to another site).

    I could also upgrade the switches at the site with something more user friendly. This is the site where I've blown up a half dozen switches and never could really figure out why until I kicked most things off the wired network and onto Wi-Fi. It could have been a ground loop between different buildings, a faulty device somewhere, or a bad cable.

    But also I don't want to throw parts at something that might not need parts.

    I've done packet inspection and nothing looks amiss. Nothing is trying to talk to the Internet in a weird way. No security issues that I've seen. Nothing rogue on the network.

    I'm not really sure what to do at this point. This is so perplexing.

  32. The system is back online. I just upgraded the Proxmox Cluster base to v9.2, something I’ve been putting off for months. However, since support for Proxmox 8.x expires on August 31, I finally got around to it. Proxmox is based on Debian (in this case, the upgrade was from Bookworm to Trixie), but with 15 LXCs and VMs spread across 4 servers, you never know. No #backup—no mercy. 😉

  35. pmg-userprefs-sync ist jetzt öffentlich

    📬 Wir haben pmg-userprefs-sync veröffentlicht:
    code.awit.at/D3/pmg-userprefs-

    Das kleine Tool hält auf zwei unabhängigen Proxmox Mail Gateways die persönlichen Welcome-/Blocklisten aus den Quarantäne-Digests synchron. So wirkt die Entscheidung eines Empfängers unabhängig davon, über welchen gleichpriorisierten MX die nächste Mail ankommt.

    Der Ansatz ist bewusst restriktiv:

    - Peer-Daten nur lesend über die PMG-API mit Auditor-Rolle
    - Änderungen ausschließlich lokal über pmgsh
    - add-only: keine automatischen Löschungen, kein Datenverlust
    - kein PMG-Cluster, kein pmgcm, kein SSH zwischen den Gateways
    - Dry-run als sicherer Standard, systemd-Timer optional

    Nicht synchronisiert werden Filterregeln, Transports, TLS-Policies, Spam-Scores oder Quarantäne-Inhalte. Das sind bewusst getrennte Themen mit anderen Risiken.

    Getestet mit PMG 9.1.2 auf zwei produktiven Gateways. 🔧
