Maybe the IO scheduler is not the right one?

@eeldivad i turned on "override-certs" option and it seems to work now. I'm still curious why the other build fails. Does anyone know how i can generate those 3 pem files manually to test?

This is solved. What I ended up doing was installing ubuntu and doing the whole install as root. Thanks for the help, I hope I can use XOA in the future!

@olivierlambert said in XOCE - Language not keep when i come back (surrely dumb question): Why? I mean you are the first person to ask this. It's more work to do that and I'm not sure to really see the value A cookie is the perfect simple way to store info that are from your same browser/session, so it's very logical. Yeah, I don't see the value in having to keep a user preference within XO itself either.. just don't clear your cookies. It's what they are meant for.

Thank you for your attention. It worked!

@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?

@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

@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.

came across this topic.. i have exported a vm and trying to import it to another xcp.

@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!

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
