I decided to burn my lab down because of some trouble and wanted to start fresh to isolate any problems I may have created in the past. Wiped the disks, built a new NFS share ready for work, installed the XCP-ng OS and configured networking for the management interface on the local machines, all normal stuff. Went back to my desk and logged into XO Lite on each machine, using console --> xsconsole I was able to get all the hosts into a pool, and add an ISO and NFS SR, all seemed to work.

Went to the New VM to create a simple Debian vm on which I intended to host XO-CE from sources. Typed the info in, chose the Debian image from my ISO SR, the rest of the config as normal. Uncheck the boot after creation box, and create.

Click on the VM to bring the console up, then click power on... UEFI loader comes up, and ... Can't find the boot disk. Tried another iso that I knew was capable of EFI boot, same.

Realized I was trying to start in EFI, made a new one in BIOS mode, this one worked but now my screen shots are messed up so I'll probably have to go through and delete stuff with a different XO and go back to grabbing images of the process to write up "for the next guy".

Other than this small issue, it's working and doing it all from XO Lite. Yes still a bunch of missing features, but I know you are working on this. I just wanted to try things this way on this fresh build and see what I could get done from local console and XO Lite.

BTW, the ram increase made zero difference in the VDI migration times.

I may still change the ram for each host in production, but I only have like 12 VMs right now and probably not many more to create in my little system. Might be useful if I ever get down to a single host because of a catastrophe. Currently running what it chose for default at 7.41 MiB, roughly doubled that in my lab to see what might happen.

Just got my VMware lab started so all this other stuff is going to back burner for a while. I will say I like the basic ESXi interface that they give you, I can see why smaller systems may not bother buying VCenter. I hope XO-lite gives us the same amount of function when it gets done (or more).

I was looking for a way to mark this solved, can't find it.

I haven't moved things, but after migrating my big lab to my mini-lab, I'm confident that the warm migration is the way to go. It was fast and seamless as long as you have the right network adapters set up. I had to fool with one of my networks to make a VM function, but that was certainly something I overlooked while setting up the mini-lab. A little testing before moving the VMs should make this go easily if using the old servers is the option for this project.

Having what is essentially XCP-NG Center from a browser would be nice, no more need to install something on a Windows machine just to get some basic stuff set up until you get a full XOA instance running. Yes I know you can just grab the demo with a single command, but sometimes you want to configure a few things first.

Documentation is the first thing to get pushed to the back burner, same in my area, same in my larger IT department. Never enough time to document things correctly.

I need to get going with Netbox and see if I can make this speed up what I want to document.

trobertson

Ummm... Your documentation sure makes a lot of us jealous!

Was that just a layout program like draw.io, or are you using something like Netbox for that work?

I'm starting on GLPI to handle more than just flow paths going forward, need to track serial numbers, date of purchase, maybe installed software as I go forward. A project for the summer.

So there might be two other things to look into if you get bored.

It is not cheaper, but it draws about half the power when idle. When doing work the power still gets up there, they are 60-90 watt computers, which is still less than the 300 watt capable HP servers at full go.

If you really stress your lab a lot, real servers are a win as they will draw less power for more performance, but if yours is like mine and it idles a lot, cutting the power is nice. I'm about 200 watts at idle with the above, and that's two labs worth. I was 400 with the single old lab system.

Mounts are cheap book ends, drilled and screwed to that specific shelf, and drilled for short m4 thumbscrews to get into the VESA mount on the t740.

If anyone reading this wants to duplicate, and they see HP T755 cheap enough, I recommend these because it has 6 cores / 12 threads over the t740 with 4 cores / 8 threads. Both are DDR4 sodimm and top out at 64GB. Both have a PCI 3.0 x8 (x16 slot) that takes half height cards. And if the BIOS is locked, you can write over them with a programmer and enter the data needed to function (see badcaps forum for my guide).

Here is mine

HP DL360e Gen 8 for Truenas, 96GB of RAM, more processors than it needs, and 8x500 drives, NFS share for the VMs

3x HP DL360p gen 8 for XCP-NG with 128GB of RAM and 20c40t worth of processors.

10gbps networking to a Mikrotik switch, also an old Cisco 2960s for a second gigabit network (with POE+)

There is also a cheap GPS/GNSS NTP clock at the top of the rack, just too far to show these other items.

I like the spinning lights on the drives, just wish it was a little faster.

Thank you, that's what I thought and why I was willing to buy the lower end CPU in order to get the project through. At the time going for the larger Gold would have doubled the cost of each server.

Do I need to change each host or just the pool coordinator? Since my lab was recently rebuilt, I might as well get on the testing branch.

Will this installer remove the Xenserver drivers if they are already installed? Or should I use the cleaner first?

The instructions say to remove secure boot, then run a powershell script, isn't this going to cause a problem with Windows 11 and maybe Server 2025? Can secure boot be turned back on after the powershell script has been run?

I'm trying to slice out some time to work with Server 2025 in my XCP-ng lab so I can move forward in my production system when I'm comfortable with the upgrade. I'm on 8.3 stable if that matters, I could move to 8.3 testing if needed for these drivers/management agent. I'd really like to move away from Xenserver drivers because I just don't trust them to remain available in the long term.

I'm also trying to keep my Server 2025 in UEFI, Secureboot, and vTPM going forward. We are going to be forced sooner or later so I might as well get familiar with any problems that might appear now while I can test.

Off topic, XO-Lite is really moving along. I have screen captures for setting up a system from install using XO-Lite. This gets me up to installing Debian for an XO from sources VM to go farther. Keep up the good work!
