XCP-ng Center 25.04 Released

[Andrew]

@michael.manley Thanks for the update! I still use it, mostly for the direct (not web based) console and it can still do a few things XO does not.

The update did not replace the old version (also different install location), but that's ok. I just uninstalled the old one and reconnected to the XCP servers.

Hi, I test Build 25120 ( rev: d7ac261f ) and Is working with XenServer 8.2 CU 1 and XCP-ng 8.2 LTS.

Great Work, thanks for all

[LukeBlodgett]

Working well for me on XCP 8.3. Thanks for all your hard work on this!

Hello, I noticed that in this new version there is no option to connect to the server via Active Directory. I still use version 20.04.01 and this feature would be very useful. I would appreciate it if you could return this option.

@crismarcul Yes, I would also like this option. It is essential.

[michael.manley]

@crismarcul Authenticate via AD or somthing else? I remember seeing before that the auth via AD code in XCP-ng itself was removed to require use of XO instead but I'm not 100% sure.

[DeOccultist]

@michael.manley The "Join Domain" option in the Users tab.
Keeping this will be very useful.

Hi, with this modification on MainWindow.cs in

        private List<TabPage> GetNewTabPages()

adding this at the end:

           if (!multi && !SearchMode && (isPoolSelected || isHostSelected && isHostLive))
                newTabs.Add(TabPageAD);

the AD tab appears:

I test this modification and is working.

Maybe @michael.manley can update this and the modification to support attach iSCSI SR without error with gfs2

[Dude417]

Lovin' this.... thank you for picking it up. Great tool to have.

GFS2 isn't supported in XCP-ng at all, and is only supported in Citrix Hypervisor, the fact that it works is pure chance.

[uberiain]

@DustinB I think I expressed myself poorly; the iSCSI SR creation test does not remove the gfs2 check and does not allow it to be created as LVM.

In LVMoISCSI.cs if you set:

var performSecondProbe = Helpers.KolkataOrGreater(Connection) && !Helpers.FeatureForbidden(Connection, Host.RestrictCorosync);

The SR can be created.

Sorry to ask, but I can not find any code/compiled program to download on this page.
I find this github page not user friendly at all - maybe fine for developers, not for users. Maybe I just dont see it...

Could you please shed some light on it, that I can download it?
Thanks for your help!

@JBlessing At the bottom of the release page (https://github.com/xcp-ng/xenadmin/releases/tag/v25.04) are the links to download either the MSI installer or a Zip file containing the entire application (if you want a portable package).

@kagbasi-ngc Thanks for your help. I found the culprit: Brightcloud Webfilter was blocking parts of the github site - I was wondering why it looked so .. weird...
My fault not checking it beforehand.

@JBlessing You're welcome!

This will add the tab back in XCP-ng Center but I don't think it works in XCP-ng 8.3.
I just upgraded from 8.2.1 to 8.3 when I logged into XCP-ng Center I saw the error message

Active Directory authorization is not available","Server 'xcp-ng-TEST' has failed to connect to the Active Directory server.

INTERNAL_ERROR: [ Xapi_systemctl.Systemctl_fail(""INTERNAL_ERROR: [ Subprocess exited with unexpected code 1; stdout = [  ]; stderr = [ Job for winbind.service failed because the control process exited with error code.

I haven't figured out what to do yet. None of the users can log into XCP-ng Center using their Active Directory credentials and only root can log in.

EDIT: Actually winbind wasn't even used in XCP-ng 8.2.1, I'm not sure why this service started up in 8.3.

XCP-ng 8.2.1# systemctl status winbind.service

But I can see that windbind is used for XenServer 8.4 https://docs.xenserver.com/en-us/xenserver/8/users
Anyone got suggestions on how to get AD authentication working with XCP-ng Center again? Or add users manaully?

SOLUTION:
What I found after following the steps in the in the XenServer page above is that if I disable AD Authentication then re-enable it then it will work.

To Disable AD Authentication:
xe pool-disable-external-auth

Enable AD Authentication:
xe pool-enable-external-auth auth-type=AD service-name=full-qualified-domain config:user=username config:pass=password

Without the Users tab in XCP-ng Center, CLI command is needed to add or remove users. Refer to the XenServer page above.

xe subject-add subject-name=entity_name

@uberiain at this point, when I am uninstall the old XCP-ng center software, and install the new msi, I just realized the xcp-ng keeps the settings file in Roaming folder. (C:\Users\user\AppData\Roaming\XCP-ng)

When I deleted it I could re-register the servers.
