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

#ProxLB compatibility tested with #Proxmox 9.

Also added a compatibility matrix, now.

Probably the most interesting new feature in Proxmox 9 (Beta 1):

Finally we're able to create #Snapshots of VMs with shared block storage (such like #iSCSI, #FibreChannel & #NVMeoF) with LVM Thick without doing dirty workarounds. Well done Proxmox (& Alex!).

Recently, I created a plugin (including PVE UI integration) for #NetApp based storages to create storage side snapshots.

PS: #ProxLB also already supports PVE9!

Let's test #Proxmox 9 (Beta 1).

Time to test that all automation stuff still works with PVE 9; also ProxLB & Co :)

How I quickly spawn my #Proxmox Labs - Proxmox Cloud Image & Proxmox Bare-Metal Auto Installer

This way, you can just spin up your cluster in less than 5 minutes and continue your tests :)

Pssssst - ProxLB 1.1.5 for your Proxmox Clusters has been released!

Just one small new feature:
* You can now use custom ports for the API request

This becomes handy when using additional/external load balancers on different ports than tcp/8006. Have fun :)

Simply NUC has their moonstone line that might be a good option for a homelab virtualization platform. The base models for an AMD start at $649 and I can upgrade the RAM separately.

Bulk Proxmox Subscription Management with my new Ansible module: proxmox_node

Moving over to Proxmox? Mass deploying hundreds of new nodes? How to import the subscription? How to manage the node in an API driven way?

currently fighting a very bizarre issue with #proxmox where the guests get terrible download speeds and a not as terrible upload speeds but the host has a full bore 10gb duplex. i'm talking like 7mbps down on the hosts and 600..ish mbps up.

if i had any hair left i'd be pulling it out...
