#ProxLB start supporting #Proxmox's native HA rules (affinity/anti-affinity) with release 1.1.11.

This way, you can simply use the built-in rules via the interface, but still use enhanced rules via ProxLB by tags or pools (even for non HA VMs/CTs). This feature was already requested a long time ago and get's now streamlined over all ways, ensuring we can balance our VMs (and CTs) across the nodes with and even without any configured HA objects - fully flexible to your needs!

Requirements:
* Proxmox 9.x
* ProxLB 1.1.11

Version 1.1.11 is expected to be released by the end of this or within the upcoming week; depending on my spare time.

PS: Keep in mind, tomorrow starts our "Virtualization Gathering" at @credativde and I'm providing a talk about my @BoxyBSD project where I tell you a bit more about the infrastrucutre/hypervisors (due to the limited time only very high level)! Feel free to join, it's free!

Still looking how to balance your VMs in #Proxmox clusters? #ProxLB 1.1.9 is here!

This release adds features that were requested during the #DutchProxmoxDay2025 which was hosted by our friends Tuxis (tuxis.nl). I'm hearing your feedback and all your feedback from the community and user base is important to me, so let me introduce the following new features:

* Add an optional memory balancing threshold
* Add affinity/anti-affinity support by pools
* Add pressure (PSI) based balancing for memory, cpu, disk
* Pressure (PSI) based balancing for nodes
* Pressure (PSI) based balancing for guests

You can simply upgrade via APT or by obtaining the latest Docker/Container image. PSI based balancing (still in beta) requires Proxmox VE 9 or greater.

Thanks to my employer
@credativ (https://credativ.de) who provides me the required time to work at this.

We at @credativde are launching our very first & free open-source virtualization gathering in Germany, Mönchengladbach.

This new community event brings together everyone who’s passionate about open virtualization technologies, whether it’s Proxmox VE, XCP-ng, bhyve, Harvester, or any of the countless projects that make open infrastructure thrive. It’s about sharing experiences, learning from each other, and connecting with those who build and rely on open platforms every day.

We start the evening with two talks:

* "Enterprise-Ready? How people use Proxmox VE & Ceph" by Ronald Otto from Tuxis B.V.

* "BoxyBSD – Creating a free VPS hosting platform" by Florian Paul Azim Hoberg from credativ GmbH

Afterwards, the space opens up for discussion, networking, and casual chats. If you like to join with a talk, please feel free to reach out to me.

#Incus impressed me as a #Proxmox alternative, but #IncusOS? That’s the next evolution!

IncusOS comes with all the missing things like ARM64 (aarch64) support, boot safety, full disk encryption, immutable images (read-only and signed) and fully locked down to operate in API only mode.

For me, it’s a mix of #Talos, #Harvester and Proxmox where it merges the best features of all ones!

On Thursday, @gyptazy provided a talk about #BoxyBSD at the "Virtualization Gathering" at @credativde.

@gyptazy provided some more information about the BoxyBSD project, but also about the history and infrastructure including the switches of #FreeBSD #Jails, #bhyve and #Proxmox (#kvm). Afterwards, additional information about the #Sylve project were shared and why this is so important and interesting and could make BoxyBSD return to bhyve based #virtualization.

#ProxCLMC 1.2.0 for #Proxmox Clusters has just been released!

ProxCLMC detects the best CPU mode for VMs across all nodes in a cluster to guarantee safe live migrations.

I really love to see #Sylve in #FreeBSD allowing us to define CPU pinning with #bhyve! That's a missing piece in other "major" solutions... Well done!

#ProxLB 1.1.11 for #Proxmox clusters introduces many new features and now fully aligns with Proxmox’s native HA rules.

ProxLB 1.1.11 was released, focusing on deeper integration and smarter balancing for Proxmox VE clusters. This version introduces a beta integration with Proxmox’s native HA and affinity/anti-affinity rules (please report any kind of bugs!), allowing ProxLB to work seamlessly with existing placement constraints instead of duplicating them.

The balancing behavior has also been improved: operators can now prefer smaller or larger VMs during placement, and node memory reservations are respected to reduce overcommitment.

Overall, 1.1.11 makes ProxLB more predictable, safer, and better suited for production use, while paving the way for future HA-aware scheduling improvements.

#PegaProx as a multi-cluster, node & vm manager for #Proxmox based systems is just around the corner!

PegaProx steps in as a real manager with a feature set that you might already know from enterprise solutions which simplifies and standardizes the management of Proxmox based infrastructures.

Each capability focuses on reducing operational complexity while giving operators full control over clusters, nodes, storage, and virtual machines like:

Unified Multi Cluster Management
Node and Cluster Monitoring
User & Group Management
Semi-automated Node Security Patch Management
Cross Cluster Migration
Virtual Machine & Container Management
CPU Alignment over Nodes for safe VM live-migrations
Intelligent Load Balancing for VMs
Intelligent Load Balancing for Storage
High Availability and Failover
User-, Group- & Tenancy Management
And much more...

Instead of just providing and visualizing metrics you can finally completely manage the whole stack: Creating VMs, adding storage, maintenances, PVE node patch management, DRS alike balancing by #ProxLB, CPU compatibility mode for VMs across all nodes (like #ProxCLMC), Tenant support, API and much more!

This will become a game changer for Proxmox users - especially in enterprises which adds all the often requested but missing functions!

You can already find my first insights about it in my blog post: https://gyptazy.com/blog/pegaprox-real-datacenter-manager-proxmox-clusters/

Adding the new #syslog feature to #PegaProx for #Proxmox clusters during Easter is basically: hiding eggs → finding eggs → realizing some eggs are actually critical alerts

For real, many people asked me for their smaller and mid-sized environments, how to handle remote syslog of their nodes. I had some ideas (some of you may have already found my Rust interpretation of this) but I think having this included in #PegaProx as a centralized management interface makes more sense.

So, PegaProx comes with an own syslog server (ipv4/ipv6, udp/tcp, encrypted/unencrypted support) and is wired to the interface within the resources tab. Providing a quick overview of all your logs and filter options. The next thing is wiring it to the notification system of PegaProx, allowing automated alerting. Might be nice to quickly identify when the quorum got lost - all built-in into PegaProx!

Missing a centralized overview of all your snapshots in your #Proxmox clusters? #PegaProx has you covered!

Recently, I added #ProxSnap to #PegaProx which allows you to quickly find snapshots of your VMs and Containers. You can also filter them by date to quickly identify older or even outdated ones and clean them up at a central point!

https://blogs.gnome.org/feborges/future-of-boxes/

Last week I had several meetings with customers where I also showcased the #PegaProx project for #Proxmox.

The feedback was honestly amazing. Many were impressed by how PegaProx brings essential enterprise grade features to Proxmox clusters that are still missing today. We can clearly see the gaps that were fixed by #ProxLB, #ProxSnap, #ProxCLMC, #ProxPatch and many other ones! Keep in mind, PegaProx is free and fully #opensource!

That said, we know there's always room for improvement. Whether it is major enhancements or small quality of life tweaks, every detail matters. Over the weekend, I took your feedback from the calls seriously and integrated a number of improvements to make PegaProx even more intuitive and powerful.

Your input drives this project forward. If you feel something is missing or could be improved, let us know!

PS: Pegaprox also support #XCP (#XCPng) ans corss-cluster / cross-hypervisor migrations. So, you can quickly jump over to XCP 🙂
