moondevon Kubernetes on Oxide: How customer needs shaped our integrations

Could there theoretically be a swappable hypervisor for oxide some day? I'm imagining a oxide Linux distro of sorts running on the hosts, and using kvm for vms, but still oxide control plane bits downstream. Then you get nested virt and gpu support, and could maybe even virtualize a traditional oxide host. Like running multi-host vcenter clusters inside a single esxi, amazingly powerful lab scenarios, teardown is even fun

Love to see the CAPOx provider and buy in to Cluster API

moondevon Proxmox VE now available for ARM64

Unfortunately as of today DGX Spark doesn't support GPU PCI passrhru for KVM

A good alternative is incus and running LXC and or OCI containers, GPU works in those and can be shared with multiple instances

What if this project offered binaries from GitHub releases instead? How do you read those?

It's more realistic to decide if you trust the source, GitHub user yamafaktory in this case. Then you can ensure that your method of download uses TLS.

moondevon You can now run same OCI images as containers or Firecracker microVMs

If you run an ubuntu image with a kata kernel, do you have difficulty installing some packages? For example if you need linux-headers-$(uname -r) or linux-modules-extra-$(uname -r), it won't exist in canonical apt repos?

moondevon I tested every IP KVM in my Homelab

The HP z2 mini g1a supports a BMC module that is a full redfish implementation, so it can do virtualmedia and UEFI configuration read/write.

I was pretty disappointed to discover DGX spark has no BMC. I was able to hook it up to pikvm by connecting leads to the power switch wires. It honestly works really well and I can provision it with MAAS

Shout-out to pikvm for their redfish support with the pikvm switch

Great writeup there are quite a few here that are new to me

moondevon Apple's accidental moat: How the "AI Loser" may end up winning

How is changing the architecture of a platform that only you make hardware for doing the impossible?

They could change the architecture again tonight, and start releasing new machines with it. The users will adopt because there is literally no other choice.

Every machine they release will be fastest and most capable on the platform, because there is no other option

moondevon Apple Silicon and Virtual Machines: Beating the 2 VM Limit (2023)

You are confusing macos guests on KVM (Linux) and macos guests on ESXi which is a real enterprise product, and officially enables you to run as many macos vms as your hardware supports.

moondevon Apple Silicon and Virtual Machines: Beating the 2 VM Limit (2023)

An artificial limit on the number vms you are allowed to launch doesn't make it solid

moondevon Apple Silicon and Virtual Machines: Beating the 2 VM Limit (2023)

VMware vSphere is not a product intended to be used by consumers. It's intended to be run by enterprises at scale. ESXi is running the vms not macOS.

moondevon Layoff Thinking

Being unexpectedly unemployed also starts a virtual timer of sorts not on your terms. Regardless of how you feel about the event, the longer it persists is universally seen as a negative signal to those that would hire you for your next role. It gets exponentially worse as time goes on making it even harder to find a job, because of the increased time you don't have a job.

moondevon Apple Silicon and Virtual Machines: Beating the 2 VM Limit (2023)

Imagine buying a mac studio with 500+ GB of memory and being limited to 2 vms.

moondevon Apple Silicon and Virtual Machines: Beating the 2 VM Limit (2023)

The VM limit only applies to the number of macOS VMs launched from macOS itself.

My 2018 mac mini officially supports VMware ESXi to be installed directly on the hardware and virtualize any number of macOS machines

Funny enough I can even launch more than 2 macOS vms on my framework chromebook with qemu + KVM from the integrated Linux terminal.

moondevon MAUI Is Coming to Linux

Things like this remind me how much I love open source software. Choice is amazing shout out to all the contributors!

moondevon Cockpit is a web-based graphical interface for servers

Yes that is the package. It's just like the canonical ui for lxd, but it also supports the incus enhancements like OCI containers.

Very handy to generate yaml config for machines and viewing their console / terminal.

moondevon Cockpit is a web-based graphical interface for servers

> I'm feeling like it is hard to find a simple GUI to just review a system and manage a bunch of containers and VMs.

Incus does all three through the same web ui

* OCI compatible "app" containers - with support for registries like docker.io and ghcr.io

* LXC "system" containers

* virtual machines with qemu + kvm

moondevon A decade of Docker containers

That's why I love Incus. It offers all three so you don't have to choose. OCI app containers, LXC containers and KVM.

moondevon Show HN: Kappal – CLI to Run Docker Compose YML on Kubernetes for Local Dev

Just like KIND runs containerd inside docker, you can also run dockerd inside containerd backed pods.

Start a privileged pod with the dind image, copy or mount your compose.yaml inside and you should be able to docker compose up and down, all without mounting a socket (that won't exist anyway on containerd CRI nodes)

To go even further, kubevirt runs on kind, launch a VM with your compose file passed in via cloud-init.

moondevon Independent Guest Virtual Machine (IGVM) File Format

This looks like OVA, firmware can be bundled inside along with additional disks, networking config, machine type and so on.

So essentially a virtual appliance package
