@olivierlambert said in XO Community Edition - Ldap Plugin not working ?: If there's no issue in XOA but XO from the source, it's very likely an environment problem, because we don't have any specific LDAP code difference between source and XOA. What exactly do you mean by this? I'm not a developer, so in almost all cases I defer to you - @olivierlambert - and the other knowledgeable members of the Vates team. However, in this case, I'm struggling to accept your logic. If by environment you're referring to the Active Directory configuration, then - at least - in my environment, that is the common denominator (i.e., the variable that hasn't changed). The fact that XOA works against the same AD domain but XOCE doesn't (unless a user's security groups are limited to no more than 2), hints to me that something is different in how the LDAP plugin is being implemented in XOA. Now, I didn't compile it myself but relied on @ronivay's install script, so it's very possible that perhaps there's something in how he compiles that's causing the issue - but I feel it important to emphasize that the AD environment hasn't changed - at least in my environment. I have other systems that are authenticating against the same AD backend, that I'm not having any issues with. If you guys can dedicate some time to troubleshooting this issue, I'm available to assist in any way possible (even if it means burning the midnight oil - just let me know).

@payback007 said in vm start delay - does it work yet?: unfortunately "start delay" is not working as expected. The function what you marked above is to change the start delay of an existing "vApp". Here is an example of my setup: [image: 1558128450595-04e7439d-6b92-4356-aa23-14d704588be3-grafik.png] The value whould change the "Delay interval" later by XOA, nothing else. Otherwise is vApp feature also not working on my XCP-ng installation, I think it was never really tested. If you want to implement start delays to your VM's you can follow this guide: define vApp for autostart in xcp-ng center including start order find out the uuid of the vApp: xe appliance-list write autostart script containing #!/bin/sh xe appliance-start uuid=uuid-autostart-vApp implement new systemd.service in /etc/systemd/system/autostart.service [Unit] Description=autostart script for boot VM After=graphical.target [Service] Type=simple ExecStart=/path/to/your/autostart-script.sh TimeoutStartSec=0 [Install] WantedBy=default.target enable the service systemctl enable autostart.service Editing of boot delay time is then possible via XOA which is already a nice feature at all for "fine tuning" or adapt if new VMs are added to the autostart vApp. @olivierlambert whould it make sense to open an additional feature request? vApp-implementation was several times discussed with no "final statement" I think. When I have a pool without HA, how could I use this script? I thought about setting the script on the master server. However, in a maintenance, where a second node becomes the master, will I have to recreate the script?

@Mefosheez Marking a new post as a question will not be necessary. @anthonyper is the one working on what we think is the issue (a regression on the EDK2 package). I haven't heard of a fix yet, but it's in progress.

@Chico008 What does it show for the commit on the About page in XO?

@Danp It wasnt a VM. I dedicated a whole PC to debian and XO. But I was completely clueless as to what I was doing. I am off and running now though. Thank you

It looks like this issue occurs only when saving the backup to non-block storage. When saving to block storage ("Store backup as multiple data blocks instead of a whole VHD file: ON"), it does not, at least in my environment.

@merango said in XOA Install Issues: @merango Hi DustineB, Thanks for the help, after looking at the BIO, I have a question around the management server. I have a spare windows 11 Pro PC that is running a Hyper-V Ubuntu 24.04.1 bare install. Can I follow your guide to install this as the MGMT server for my XCP-NG host on the same LAN? I'd prefer to manage it on a separate PC if possible and that would work nicely if that is possible? Of course you can, anywhere you can install Debian or Ubuntu can you install XO. Be it physical or virtual.

I'm adding @dinhngtu in the loop in case we can makes sense of that, but it's really strange indeed.

@DustinB tried your command, it runs OK, restarted the vm hosting XOCE, but still have the same issue after typing an @ in console, char following are wrong

For information : The downgrade change nothing. The only solution was to reinstall xcp with the upgrade option (even if it was up to date before the bios update) If we go back to the original problem, the latest version of the Bios changes nothing (there is no information about the BIOS on the Host page)

@Danp it turns out I had a typo that took me forever to find . . . 102 vs 192 in the gateway ip. The strange thing to me was that the internal networking was working (pings, connections, etc). But there's something in the xoa web site that could not make the connection to the server it was running on, which makes me think there is some kind of external communication going on for server connections. If xoa can ping the dom0 then why would it need the gateway to connect to it for the web interface? Anyway I fixed the typo after finding the error running ip monitor, and then everything works great. This was the 3rd or 4th install of xoa so I was getting a bit hurried . . . next morning it took 2 minutes to find the error. Now its registered and working.

@olivierlambert Can't wait. V6 Gui is really nice Most of my colleagues are saying it's sexier than vcenter

It also happens when you run xo-server as non-root user.

@olivierlambert said in Mirror failed: @AlexanderK said in Mirror failed: "OLD_447ff17a-82bc-4d49-a177-02f9086e9a04 That's the missing bit reported by XAPI/SM, indeed. Does this mean it is a bug?

@Meth0d thanks for sharing your experience. Fortunately I was able to just hit "Convert to HVM" after my imported PV failed to reboot after upgrade from 20.04 to 22.04 - was all set to load a livecd etc too!

Using XOA "Disaster Recovery" backup method can be a lot faster than normal offline migration. One time I did it, it took approx 10 minutes instead of 2 hours...

yep i know but i think it is much better to have 2 Ext SR each with 1 hdd than to have 1 SR with a raid with 2 hdd, regarding downtime in case of failure disk
