New Open-Source Tool Spotlight

Firecracker is a lightweight, production-focused virtual machine monitor designed for secure multi-tenant workloads. Its minimal overhead enables high density on bare-metal servers while emphasizing isolation through microVMs. Built by AWS, it's used in services like Lambda and Fargate. #Virtualization #MicroVM

So close to remote image flashing for #Android servers!

The VM is dropping the USB device when `adb -d reboot bootloader` since I am USB forwarding NOT using PCI passthrough to qemu.

```
services.udev.extraRules = ''
SUBSYSTEM=="usb", ATTR{idVendor}=="18d1", ATTR{idProduct}=="4ee7", GROUP="kvm"
'';
```

Once it reboots and goes offline briefly the systemd service drops and doesn't reattach to the VM. Will need to figure this out

My #NixOS 23.12 upgrade story for all the servers and VMs I manage:

Let's start with the terrible. Grafana crashed because it is missed a directory when using provisioned dashboards. Fix is in https://github.com/NixOS/nixpkgs/pull/272564

Then I searched an hour for a faulty change I did two days ago where I didn't think about split Portunus LDAP server and applications and needed to move a mkIf.

That's two #MicroVM|s done. The next two just worked without any changes and nothing broke (so far?).

Starting to #bisect #edk2 #ovmf stuff because the #microvm blobs don't build anymore since last release...

If only they had a build system that is at least somewhat comprehensive and not a bizarre monster of #shell and #python scripts mangled together with some #make and other bits and pieces
