Stephen Smith ☛ Virtualizing Ubuntu on an M-series Mac
Recently, I had a look at Ubuntu 25.10 running in a virtual machine running on my old Windows laptop. I chose this as I figured VMWare was the easiest way to get running quickly. When I downloaded Ubuntu, I noticed there was an ARM64 version posted right alongside the Intel/AMD one. This made me wonder how easy it is these days to run virtualization software for free on MacOS with an M-series Mac, meaning running Apple’s ARM64 processor.
When I first received my M1 Mac back in 2020, Parallel’s desktop virtualization software was available for free as a beta which I used and it worked pretty well. This software is now either $65 per year on a subscription or $286 for a one time purchase. So I thought I’d have a look around for something ideally open source. As a result I found UTM, so this article is about running Ubuntu 25.10 on my M1 Apple Mac as a virtual machine under UTM.

Dan Langille ☛ Test run – moving to a smaller zpool (zroot) using zfs snapshot and send | recv
Today, I’m going to try a test run of moving a zroot into a smaller zpool. Over the past few posts, I’ve tested moving to smaller zpools using zfs remove. That’s not what I want to do with my zpool – mostly because it does not leave you with a functioning original zpool.

Dan Langille ☛ Moving a zpool to smaller drives with UEFI #ZFS #FreeBSD
This is another in the series of shrinking zpools. In this test, I’m repeating the previous test, only with UEFI, not BIOS, boot partitions.

Dan Langille ☛ Moving a zpool to smaller drives #ZFS #FreeBSD
After succeeding with whole drives and with partitioned drives, I’m ready to try with more complex partitions. This is a repeat of the failed attempt a few days ago.

Dan Langille ☛ Let’s try shrinking a whole-disk zpool
Today, I’m going to try the same thing with whole disks, just to see if that works.

Dan Langille ☛ Doing stupid things with zpools
Over the past week or so I’ve done some “stupid” things with zpools.

Hagen Bauer ☛ Migrating a ZFS Pool to smaller disks
In this document I would like to document my successful migration (completed 2 weeks ago) of a ZFS mirror to 2 smaller disks. I started the server on 2 3TB spinning discs but I dont need the size and wanted to move to 2 2TB NVME drives.

HPC Wire ☛ Hammerspace Delivers IO500 Top-10 Result with Standards-Based Linux and NFS Architecture
Hammerspace, the high-performance data platform for AI Anywhere, today announced a breakthrough IO500 10-Node Production result that establishes a new era for high-performance data infrastructure. For the first time, a fully standards-based architecture — standard Linux, the upstream NFSv4.2 client, and commodity NVMe flash — has delivered a 10-node Production fully reproducible IO500 result traditionally achievable only by proprietary parallel filesystems.
