Ubuntu 24.04 gets a big open-vm-tools update

A major update to open-vm-tools, a package that integrates Linux virtual machines with VMware hypervisors, is rolling out to users of Ubuntu 24.04 LTS. “Without SRUing the newer version users get issues running on more recent hypervisors”, Canonical’s Lena Voytek explained in a backport request. It’s a full backport from Ubuntu 26.04 LTS to support platform enablement to benefit those running 24.04 LTS. The open-vm-tool package goes from v12.3.5 to v3.0.10 (the same version in Ubuntu 26.04 LTS). VMware’s open-vm-tools package enables clock sync with the hypervisor host, ‘graceful’ power management for clean shutdowns, vSphere API, shared folder support, relays […]

[$] How to be safe from quantum computing

Practical quantum computers have been ten years away for the last several decades. Now, however, it's beginning to look as though they will be possible in just a few years. Recent research with obfuscated results demonstrated much lower memory requirements to factor ECDSA keys on a quantum computer, with work by other researchers in the open more than halving memory use compared to the state of the art in 2023. At the same time, computer manufacturers are boasting quantum processors that retain viable superpositions over longer periods. Given how slowly software updates filter out to stable systems, it's worth looking at what configuration changes and protocol updates are needed to be safe from quantum computers now.
