XCP-ng 8.3 public alpha 🚀
-
Yep I agree that security fixes are the most important ones. And I know that security patches are provided (as I wrote in my mail).
Since I am new to XCP-ng, and I did not study the changes related to 8.3, I do not know the improvements, but I assume there are!
-
As I said previously, you should really take a look at the doc and the blog...
https://xcp-ng.org/blog/2022/11/18/xcp-ng-8-3-alpha/
And posted very recently: https://xcp-ng.org/blog/2023/02/27/news-about-8-3-alpha/

Olivier thanks for the links. But it only confirms my idea that I should go for the latest releases as far as possible!
- IPV6 support is important to me (should work!)
- all security fixes (not only the most important ones)
- better hardware support ( I do have e.g. 2.5 g interfaces)
- newer python
- better update management
-
You should really start to work on 8.2 LTS first and see what you really need in real life. If it's not enterprise production, then go for 8.3.

Summary: upgrade from 8.3alpha to 8.3alpha2 broke my installation.
Yesterday I tried to upgrade my Intel NUC11 from the original 8.3alpha (very stable so far) to the 8.3alpha2.
The upgrade process concluded without errors, however upon restart while the host was accessible via SSH, all the rest disappeared (no XOALite, no VM and obviously no XOA).
I tried to list the vm with "xe vm-list" resulting in "Error: Connection refused (calling connect)". Then I tried to restart with "xe-toolstack-restart" but without success.
Right now using the installer I reverted to previous installation... indeed a useful function
Your insights is welcome, I can make any test you might be interested in.
Thanks

Hi There,
Just to mention, my personal hopes are for the future, that whatever kernel will be used, RPM packages will still be supported to install.Usecase:
I am using Dell / Quest DR-Appliances for Backups. They've implemented RapidCIFS and RapidNFS in order to do kind of CBT enhancement on these protocols. So when backing up - only delta is copied.However, as usual, they provide this driver officially only for Windows and RHEL. Therefore I could install the RPM on the XCP-Hosts, and benefit from this. It's running amazingliy smooth.
I would assume that there might be more of such use cases, and keeping support for RHEL packages could be wise in oder to keep a foot into the "enterprise door".
Thanks, for your work!
Regards,

Thanks for your feedback RaHu

Thank you, appreciated
I followed - maybe bluntly - this reassuring sentence but I guess it meant from 8.2!
-
rRobbie Yes, it meant from 8.2

gskger Thanks! For shorter logs, could you run
./xtf-runner -aqq --hostrather than./xtf-runner -aq --hostin the future? We don't need the full list of successful tests. Only skipped and failed ones. -
stormi Of course! Picked up that habit from other posts. Should I correct my post to improve readability?

gskger No, only future ones

I have a minor feature request…
Can we get the xen-cmdline (/opt/xensource/libexec/xen-cmdline) added to the default PATH? I don’t use it too often but having it would save me a google remembering? I’ve also added to my bashrc with the name xcl. -

Probably more a fun test than a real world test. I installed XCP-ng 8.3 alpha2 run on aHP T620 PLUS Thin Client
AMD GX-420CA @ 2GHz low power APU SoC (Jaguar)
16 GB RAMAccording to Art of Server on Youtube, this Thin Client supports up to 32GB RAM. It idles around 14-17W with XCP-ng and one Debian VM running. It also features a low profile PCI-e slot that I use with a Intel Pro / 1000 PT quad port LP card.

Haha that's an interesting little machine, indeed

Hello, here my test of version 8.3 in the last weeks:
I tried to put everything I could think of in or on the machine. Different hardware and different versions of Windows and Linux, backup of XO, with and without Xen tools, etc.
So far no crashes or major problems, even if I drove the machine to the limits of its resilience, everything runs smoothly and for days, for this a thumbs up.
Hardware:
Dell Poweredge 730, CPU 2x E5-2698 V4, 512GB RAM
2 x Intel I350 1Gb adapters
2 x Intel X540-AT2 10Gb adapters
1 x Dell H730P mono Raid Controller (5 x 8TB Disk in Raid5)
2 x SSD in Raid 1 as Boot Drive
1 x PCie NVMe Adapter (4 x 2TB NVMe Disk in Softraid 5)
( Yummi, over 1 GByte/sec write speed in a VM with 2 TB of Data)
1x Nvidia K80 GPU cardThis is without a doubt the biggest test machine I've ever had.
I have tested so far:
All standard functions (Copy, Move, Migrate, Snapshot etc.)
Use of GPU (Windows VM)
PCI passthrough (Windows, Linux - NetCard, USB, PCI card)
SR-IOV (see comments below)
Backup with XO
Heavy network load (copy 26TB of data via 10 GB netcard)
Heavy CPU and GPU load (8 VM with CPU at maximum for hours)
Fast copying of large data between the different SRs in the system.With the exception of the SR-IOV, no problems were encountered and the performance was excellent in all respects.
What made me very happy was the installation of Xen-Tools under Windows 2022. I have often had the experience that after a Windows update the server no longer wanted to start due to a driver update. The problem seems to have disappeared completely, all drivers were installed automatically when the server was installed and have so far survived all updates from Microsoft without any problems. I only had to manually add the management agent.
SR IOV:
The two Intel I350 1Gb adapters no longer show up as SR-IOV adapters and have lost that functionality. They still worked under 8.2.
The Intel X540-AT2 adapters have the SR-IOV function. But when I use it, the adapter port shuts down after a short time. The Xen server still shows the card as connectet, but the network function is gone. The coupled switch shows the port as deactivated. In between, the network function is there again for a short time and the switch also shows this. The second 10 GB port runs error-free all the time. If I switch off the SR-IOV of the port, it works without any problems. Both as a normal Xen-Nic and in PCI passthrough. I copied TByte over the port, no errors.
It must be somehow due to the SR-IOV that apparently no longer works under 8.3.
I would be interested to know if others have experienced something similar or if everything works there.I would like to test the "VM snapshot with disk exclusion" but somehow I can't do it. Both the snapshot and the XO always back up the entire VM with all disks. I'm sure it's error 50 (50cm in front of the keyboard)
. Is there a detailed description of how to set it up somewhere?Unfortunately I haven't been able to test any pool functions yet, so I have to set up a second machine for that. I can't get a second machine that size. I will probably have to build 2 smaller systems with shared storage and test them there.
If anyone thinks of anything else I could test, let me know
So far everything looks very good, you did a great job.
Greetings Joerg

Thanks jhansen for all your test work done on this alpha release!
- SR IOV: that's interesting, we will probably get that feedback to XS team too, I wonder why it's broken
- VM snap disk exclusion: that should be straight forward, but I'll try to see if I can reproduce it myself.
Thanks again!
