#XCP

Anybody out there in #homelab land using #TrueNAS Scale with VMs?

I've built a nice, reliable NAS. And then I noticed that it could do VMs. Great! I thought. I have a couple different VMs running some important things like #HomeAssistant.

What I have discovered is that their VM support is terrible. Unless I misunderstand, I literally cannot do any of these things:

  • backup a VM
  • restore a VM
  • export a VM
  • import a VM
  • snapshot a VM

If I treat each VM like a full #linux host, I can back it up using something else (e.g., rsync). But if this was #xcp with Xen Orchestra, I'd have this whole thing solved in seconds.

I'm thinking about creating a big VM, running a nested hypervisor (XCP) and then running my VMs there. But that sounds like a huge faff. And even then, while I could snapshot the child VMs, that parent VM running the hypervisor would be hard to backup/restore.

I have plenty of RAM and spare CPU cycles on my NAS. But I've only recently understood how bad this VM support is. If I lost my HomeAssistant VM I'd cry.

Anybody have thoughts on this?

How to get #XCP-NG running on Apple hardware and get past that “Fatal error” at the end of the installation. Finally wrote this up so others can get this working too.

If any #homelab folks have some spare disk space and bandwidth and want to help #resist, you can #selfhost an instance of ArchiveTeam Warrior as a VM.

The VM appliances are downloadable off of GitHub and then you just launch the VM and let it work.

If you use #xcp as your #xen hypervisor, and #xenorchestra to manage it, you might think you can just give it the GitHub URL and import. Sadly, no. I got an error. But the VM is only 165M, so if you download it to your laptop and then upload it via the XO web interface, it's trivial to launch.

Ist XCP-ng eine Proxmox-Alternative? Virtualisierungslösung mit Xen

Dieses Mal schaue ich mir die Virtualisierungslösung XCP-ng an, die nicht auf KVM sondern auf Xen basiert, und ob XCP-ng eine Proxmox-Alternative ist bzw. werden könnte.

Virtualization - How’s it going? My personal and the @BoxyBSD infrastructure will be shifted. By the end of the year a multi geo located setup (Germany, France, Canada) takes place - running on #XCPng and I’m really excited.

#XCP including #Orchestra perfectly fits my requirements. Not being that nit-picky about latencies also allows me to include nodes located on the other site of the world. @olivier is doing great with XCP!

A blog post why I moved from #bhyve -> #Proxmox -> XCPng follows!

Running #Enterprise or #Homelab with #Proxmox? Doesn’t matter!

#ProxLB is now available in version 1.0.4 with some more features and fixes! ProxLB fills the gap of missing DRS in Proxmox and also brings in some more features!

There's still a lot left to do.
I need to implement the #XCP stuff into the STM32 firmware, so it can run the #startergenerator stand-alone.
Stuff like:
- Checking the firmware version on the ECU, so it doesn't poke the wrong memory address
- Reading and parsing the status of the motor
- And actually controlling the motor properly instead of just sending it a hardcoded 1 Nm torque request :D

And then also cleaning it up enough, documenting and testing it thoroughly, so it can be published.

I spent many dozens of hours losing track of time in #Ghidra (I swear, it's worse than #Factorio)

Until I had figured out the #CAN message handling, signal parsing and where and when which #DTC codes get set.
With that knowledge I could figure out, slowly but surely, what the #startergenerator needs to run.
Even #FBS4 was pretty trivial to circumvent (a single 1 written to the right memory location via #XCP)

And after implementing the ~25 CAN messages in my STM32 code I finally got this today:

Hello #sysadmin
I would like to get some shared experience from people running #XCP-ng in this context:
- at least 2 server rooms / DC
- iSCSI storage appliances
- at least 15 physical hosts
- hundreds of VM
- HA

Thanks :)

Bonjour les #sysadmin
Je cherche quelques retours d’expérience sur l’usage de #XCP-ng dans ce contexte :
- au moins 2 salles machines
- baies de stockage en iSCSI
- plus de 15 nœuds
- plusieurs centaines de VM
- HA

Merci :)

There is the CAN #XCP protocol (Universal Measurement and Calibration Protocol) which does pretty much what it sounds like. But it's usually locked down for production.
Fortunately, this was not the case for the BSG :D
I had to hack together my own XCP dump script and it took about 20 minutes to dump the first contiguous memory segment before the BSG reset the session. (CAN is slow ^^")
Now I had exactly 2 MiB worth of some kind of data, maybe/probably the flash contents.

I've been working with VMware for much of the past 20 years, and with Broadcom now...meeeeh. If anything good has come of this situation, I'm forcing myself for the first time to explore XCP-NG, Proxmox, and Xen and KVM in general more seriously. So far I'm really impressed with what XCP-NG has become, and Xen Orchestrator seems to be heading in the right direction.

So, any Fosstodon-ers out there have thoughts and experience on Vates and XCP-NG in general? #vmware #virtualization #xcp-ng

Instalados primeros dos servers con -ng y otros 2 con .
Decidiré de cuál de ellos muevo 1 para hacer HA. Y así tengo servers de producción y de testeo.

Can I do a shout-out to my favourite #hypervisor #xcp-ng (xcp-ng.org/)? Fast install times, faster machines, easy to manage, disaster recovers is a bliss. And it is rock-solid.

I have been using it (an #xenserver initially) for more than a decade.

if you stream from my #plex server(s), EstuaryPlex will go offline at some point this weekend, EmoCloud will continue to be available.

if you've got access to Estuary, you'll get added to the new one. i'm replacing an old core i7 Haswell-era system `post` with `volta`, the 56-core monstrosity with GPUs slotted. new hardware will let me double the resources across the board.

i was going to just use proxmox again, but #xcp / #xcpNG may have ensnared me? it's just like me to 180.

Homelab update:

Upgraded the Proxmox cluster from 7 to 8. Process went smoothly for the cluster, the only issue was a Windows VM had issues booting after migrating off a host for some reason. I'll have to do some troubleshooting there.

Set up the first node in a nested XCP-ng cluster within Proxmox. I think I installed XOA but need to make sure since each time I let the installation run the terminal times out and it logs me back out before I can see the result of the installation script. Need to find out where it installs the XOA listener for the web interface. Then I'll have to read up on how to get the rest of the nested XCP-ng cluster nodes up.

Anyone else running a nested hypervisor cluster? XCP-ng in Proxmox or any other nested configuration? Any issues?

@techaddressed I run it almost exclusively! #lxd has an awesome set of features surrounding them that have changed my on-prem cloud game. I need vm's for vyos and opnsense or anything iso and I can't help to think #proxmox or #xcp-ng #vmware just kill it with the interface.

I know a lot of us IT folk love a good cli.. You just really need to understand the technology you are working with.. If you don't, man cli's really kind of suck.. at least for a little.

Now I gotta homelab the shit out of this. I'm ganna try #lxd on this thing to run my stuff!! Then of course that will flame out! #Xcp-ng will be next, that will be fine, but ultimately I'll find some shit wrong! Cause no one uses the damn thing. Then land back on #proxmox because #proxmox is #homelab pimp and if you don't come back, shit will happen to you! 😂💥🔥
