XCP-ng 8.3 betas and RCs feedback 🚀

@moussa854 You can create a vTPM with
xe vtpm-create vm-uuid=UUID_OF_YOUR_VM. -
@moussa854
And after adding it you might need some more prep? I have had no time to try more:https://xcp-ng.org/forum/topic/6578/xcp-ng-8-3-public-alpha/121?_=1687790268385

xe vtpm-create vm-uuid=UUID_OF_YOUR_VMwas enough to enable the vTPM in my case. Thank you so much.

:@rRobbie can you disable/re-enable the "Auto power on" toggle, reboot and see if it works?
If it doesn't, if the problematic VM is hosted on a storage repository that's inside a VM on the same host? (could be a "dependency" auto boot issue)
I disabled / enabled the auto power on option, then rebooted the host and it worked fine. The vm started automatically along with the other vms with auto power on which started regularry the first time after upgrade to beta.
Btw, the vm is running on local storage.
Thanks

I think the upgrade disable auto power on at the pool level (so even when your VM got it, disabling and then re-enabling will also re-enable it on the pool).
I'm not sure there's an ideal solution, except maybe display if there's a discrepancy visible in XO when you have VM with auto power on enable while the pool doesn't.

I am migrating from Proxmox and have installed 8.3 beta. So far everything looks nice.
Is SMAPIv3/ZFS-ng available in this release?
https://xcp-ng.org/blog/2022/09/23/zfs-ng-an-intro-on-smapiv3/ -
SMAPIv3 is "working", but you won't be able to live migrate the storage, export, backup etc. So it's not fully baked yet.
It's better for now to use local ext SMAPIv1 for your local disks
-
Thank you for the clarification. If I would like to test ZFS-ng, how can I do that?
-
IIRC, there some hints here: https://xcp-ng.org/blog/2022/09/23/zfs-ng-an-intro-on-smapiv3/
-
I saw your post on https://github.com/xapi-project/xapi-storage/issues/101 about the status of SMAPIv3. I also saw another comment on the project that the code has been merged with xen-api. Is SMAPIV3 stable? When you say it is not fully baked yet, are you referring to SMAPIv3, ZFS-ng or both.
Can we expect ZFS-ng support in XCP-ng at least by 2024?
closed Is SMAPIv3 still maintained? #101
-
SMAPIv3 isn't fully baked because:
- Doesn't support live storage migration
- No migration path from v1 to v3 and vice versa
But it's the future of the platform. ZFS-ng is just "one driver" written to work for SMAPIv3, which is the "framework" if you prefer
-
So, if I understand correctly, it seems that SMAPIv3 may currently lack some features, and until those features receive upstream support, XCP-ng might not be able to provide full support for it.
I'm curious about this because, from what I've seen, Vates has been making admirable efforts to enhance XCP-ng with new features. However, if this specific feature relies on upstream support, it might take some time before we can expect its implementation.
-
Let's say it's harder with the upstream, since it requires a good collaboration with other entities, that might have other priorities or not really interesting in reviewing/validating your contributions. Note it's better with some projects and harder with others.

@gsrfan01 The error happens because the joining host has TLS certificate checking enabled for pool connections while the joined host don't.
This mismatch happens because on fresh installs TLS certificate checking is enabled, while for updates from previous versions is not.
To enable TLS certificate checking in a pool simply running
xe pool-enable-tls-verification.The emergency command is not needed in this case, it's useful to re-enable certificate checking in a single host after is has been disabled using the emergency disable
-
@psafont Will a 8.2 to 8.3 upgrade (through the installation ISO) leave TLS verification disabled, or will it enable it by default?
In other words: must we expect any user who upgrades from 8.2 or lower and then later wants to add a new host to the pool to see this error (and likely ask for help, even if we document it properly - and we would of course)?

:@psafont Will a 8.2 to 8.3 upgrade (through the installation ISO) leave TLS verification disabled, or will it enable it by default?
It's not enabled by default, enabling it by default is not possible with the current update procedure where the pool coordinator is updated before the other pool member because these do not expose the new certificates to xmlrpc clients before upgrading, breaking communications.
In other words: must we expect any user who upgrades from 8.2 or lower and then later wants to add a new host to the pool to see this error (and likely ask for help, even if we document it properly - and we would of course)?
Yes
-
@psafont that's good to know, there were disturbingly few results when I searched for the error or the command.
This post is actually the top result for me now alongside a blog post from Oliver that wasn't there originally.

I just pushed a few updates to the XCP-ng 8.3 repositories. Update as usual.
- blktap, sm, tzdata: requirements for supporting XOSTOR on XCP-ng 8.3
- xsconsole: now displays VLAN number for each NIC (improvement contributed by XCP-ng users: https://github.com/xapi-project/xsconsole/pull/6)
closed add vlan display on xsconsole #6

Hi stormi !
Thanks for the wonderful release. Here are my 2 cents after preliminary testing :
Bugs Found :
The iso creates the partitions: 1,2,3,5,6 ( Partition No. 4 seems to be missing ), this is when NO SR is created at the time of install.Improvements Found [ Over previous Releases] :
The IP is allotted much faster than in 8.3 alpha release which took a long time to set-up the network.Other Notes:
Dual-Stack without static IPv6 does not seem to work. I don't know if this is a bug. Also if Dual-stack is selected at the time of installation, and the Router/DHCP does not support IPv6, even IPv4 is not allotted. Technically, if IPv6 is not available, then IPv4 should be allotted and IPv6 left without allotment. But in this case the whole system seems to have no network.Test Specs :
Processor : Intel 8700
RAM : 32 GB
SSD : 512GB + 1 TBPlease note that this is a preliminary test only and I would conduct more tests soon on Ryzen 5950X also.
Thanks once again for your quick releases !
