I consider setting up an XCP-ng server .... or perhaps a xen-server
(for private use), since I like the concept!
The problem is that the actual 8.2.1 release is over a year old ...
Looking at XEN that release 4.17 is much more recent ...
So I consider 8.3 .... however ... it is alpha which sounds as ^still a long way to go^ / not stable. I also think I would need to update from 8.2 since there is no 8.3 snapshot.iso available
So I wonder what the expected 8.3 timeline is, and to which extend XEN 4.17 is included in the 8.2 / 8.3 release.
@Louis what's the issue with 8.2.1? It's an LTS, so it's normal to use mature versions of Xen and such. It's not a contest on getting latest versions, especially since XCP-ng is very stable. What do you want to achieve?
The latest versions tend to have fixes, security updates and probably added features. For those reasons I always prefer to use the latest versions the more at the moment I start a new system.
So, I am not saying 8.2 is bad / not ok, but on the other hand I am surprised to see that 8.2.1 is over a year old. And at the same time I note that there is a xen-server release november 2022.
I assume that XCP-ng is based on xen-server. But on which version !??
Of course there have been security updates, but never the less. But I have no idea what has changed since the original 8.2.1 release. As far as I am aware there is no change log.
The latest versions tend to have fixes, security updates
Not true. All security fixes are backported. Do you really think we'll leave an LTS version of XCP-ng without any security fix since 2020?
Probably added features
Which features in Xen 4.17 you need you don't have in 4.13?
I am surprised to see that 8.2.1 is over a year old
This is not a toy project but a serious distro meant to run in a stable fashion in datacenters, at scale. Especially as an LTS version, that is expect to be maintained between 5 and 10 years.
I assume that XCP-ng is based on xen-server. But on which version !??
It's XenServer. Take a guess, XCP-ng 8.2 is based on which XenServer edition?
Of course there have been security updates, but never the less.
Never the less? That's the most important thing, to backport the sec patches.
As far as I am aware there is no change log.
You should really look at the documentation. Each XCP-ng release is covered by a change log, and each update is also documented with at least a dedicated blog post. You can start here: https://docs.xcp-ng.org/releases/ (to read what's an LTS and why we don't add features in an LTS) and there: https://xcp-ng.org/blog/ for all the blog posts on our almost monthly updates.
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...
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.
Just to mention, my personal hopes are for the future, that whatever kernel will be used, RPM packages will still be supported to install.
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!
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
