incrementally replicate libvirt based virtual machines to remote hosts using dirty bitmaps.
This utility can be used to sync or "replicate" virtual machines to other libvirt hosts. On the first execution, a complete (full) replication will be executed and an dirty bitmap is created. For any following command calls, it will only synchronize incremental changes since the last checkpoint.
Ein Vortrag über die Entstehung, Entwicklung des Incus Projekts seit 2023 und die Möglichkeiten zur Verwaltung von System Container und virtuellen Maschinen.
Incus ist ein fork des LXD-Projektes, welches viele Jahre als Teil der Linux Container Community entwickelt und gepflegt wurde. Es bezeichnet sich selbst als modernes, sicheres und mächtiges Verwaltungswerkzeug für System Container und virtuelle Maschinen.
Der Vortrag soll einen Überblick zum genannten Projekt verschaffen und klären, wie Incus gegenüber den bekannten Projekten wie Proxmox und XCP-ng einzuordnen ist.
Im ersten Teil meines Vortrags zeige ich u. a. die Möglichkeiten auf, welche Incus bei der Verwaltung von System Container und Virtuellen Maschinen bietet. Hierbei wird auch der Unterschied erklärt zwischen Application Container, System Container und virtuellen Maschinen. Im zweiten Teil meines Vortrags gebe ich einen Überblick, wie sich Incus seit dem initialen Release im Oktober 2023 entwickelt hat und was es noch so rund um Incus gibt bzw. was für 2025 geplant ist. Zum Abschluss wird es natürlich auch eine kurze Demo geben.
A Terraform / OpenTofu Provider that adds support for Proxmox Virtual Environment.
Incus is a next-generation system container, application container, and virtual machine manager.
It provides a user experience similar to that of a public cloud. With it, you can easily mix and match both containers and virtual machines, sharing the same underlying storage and network.
Incus is image based and provides images for a wide number of Linux distributions. It provides flexibility and scalability for various use cases, with support for different storage backends and network types and the option to install on hardware ranging from an individual laptop or cloud instance to a full server rack.
When using Incus, you can manage your instances (containers and VMs) with a simple command line tool, directly through the REST API or by using third-party tools and integrations. Incus implements a single REST API for both local and remote access.
The Incus project was created by Aleksa Sarai as a community driven alternative to Canonical's LXD.
Today, it's led and maintained by many of the same people that once created LXD.
clipscreen is a simple application that creates a virtual monitor that mirrors a portion of your screen. A green rectangle highlights the specified area.
Why's this useful? You can use any screen sharing tool (Google Meet, Microsoft Teams, Jitsi Meet, etc.) to share the virtual monitor instead of your entire screen. No need to share individual windows and having to switch between them, just move any window you wannt to share into the green border.
Virtual clusters are fully working Kubernetes clusters that run on top of other Kubernetes clusters. Compared to fully separate "real" clusters, virtual clusters do not have their own node pools. Instead, they are scheduling workloads inside the underlying cluster while having their own separate control plane.
Network booting is cool. Once you have setup everything you can stop juggling iso images in your virtual machine configs. Instead you just kick a network boot and pick whatever you want install from the boot menu delivered by the boot server.
This article is not about the basics of setting up a boot server. The internet has tons of tutorials on how to install a tftp server and how to boot your favorite OS from tftp. This article will focus on configuring network boot for libvirt-managed virtual machines.
General note concerning the use of guest agent interfaces:
"unsupported" is a higher-level error than the errors that individual commands might document. The caller should always be prepared to receive QERR_UNSUPPORTED, even if the given command doesn’t specify it, or doesn’t document any failure mode at all.
