@damjank Hi !

Did you have any error when trying to install the tools ?

@carloum70 Yep I tested on XOA, latest version
You can use https://vates.tech/en/deploy/ to deploy the XOA, register for free and reimport your XO configuration

@carloum70 I just tested on my side, I had some error because other disk was mounted, but after a xo-server restart, it works as expected

Debian 13, UEFI + LVM

If you are running XO form source, can you try with an XOA ?
Are you running an XO source with LVM for the OS ?

@carloum70 Hi !

Could you tell us which version of XOA you're using and what guest OS the disk you want to mount comes from?
Also, is it BIOS or UEFI?

My boyfriend submitted a PR a while ago to fix LVM + UEFI disk mounting. It fixed file restore for the guests we tested, but we might have missed some rare cases. Maybe we can provide a fix base of the info you can give

@bvivi57 Hello !

Déjà bravo pour le travail d'écriture, faire plusieurs articles aussi long, avec screenshot et commandes CLI intégré, c'est un boulot de fou !
J'ai rapidement parcouru tous tes articles, je prendrais le temps de tout relire pour te faire un feedback complet avec quelques tips, si tu le souhaites !

Sur le dernier article, j'ai vu que tu as redémarré xo-serveur parce que tu n'arrivais pas à te reconnecter au master: tu peux (dans XO5, pas encore XO6) juste aller dans setting server, et cliquer sur le bouton "disconnect" et "reconnect". Ça va forcer une reconnexion à la XAPI, et si elle est disponible, ça va reconnecter ton pool instantanément à ton XO.
Redémarrer un XO, surtout si tu as plusieurs pools, peut avoir certaines conséquences : Si tu as des backups en cours, ça va les kill instantanément, pareil pour les migrations entre deux pools différents. Il faut y aller doucement avec un systemctl restart xo-server

En tout cas merci pour ces articles, je suis heureuse de voir que la communauté francophone s'intéresse de plus en plus à l'écosystème XCP-ng/XO (et je dit ça en tant qu'"early" qui utilise la solution depuis... longtemps ! )

@fdhabhar Hi !
IIRC the host affinity is checked by the XAPI only at the start of the VM, not during its life.
So it's "normal", but not ideal, I agree

@Dezerd Hi !

Just add the third host via New -> Server, it will appear as an independent host in his own pool (assuming the third host was just installed).

@SuperDuckGuy Hi !

Are you on XOA trial and/or air gap environment ?
I remember seeing the -32000 error a while ago, but I don't remember why

You are looking on the host, right ?

Hello everyone !

I rebuild a new OME appliance with the latest version (4.6)
Dell decided to give this appliance Proxmox, Nutanix and OpenShift compatibility, but no XCP-ng yet... If someone from Dell want to reach out about this, please contact me !

What i did on the rebuild:

• Via live CD
  • add xen-blkfront and xen-netfront driver, and rebuild the initrd
  • change root password
  • activate SSH.
• Via SSH

sed -i -e 's/sda/xvda/g' /opt/dell/omc/utilities/tui/bin/ome_disk_config.sh
sed -i -e 's/sda/xvda/g' /opt/dell/mcsi/appliance/scripts/appliance_resources.sh
bash /mnt/Linux/install.sh # To install XCP-ng tools

As usual, please send a DM if you want the link to the VHD

Feedback is welcome !

(Disclamer: This build is something I create on my free time and to help people who have difficulty running Dell appliances on XCP-ng. I do not guarantee a fully functional appliance, but I do my best to make it work. If you have a support contract with Dell and require official support for OME, please contact Dell and request compatibility with XCP-ng.)

@fluxtor Hi !

First thing to check is dmesg -T, to see if you have any hardware error

Hi ! I think you need to increase XAPI timeout: https://docs.xcp-ng.org/management/manage-locally/api/#modifications

Hi !

PE2950 is very old hardware, I'm not surprised you have some issues with it
Honesty if you can, try to find newer hardware. This generation is also inefficient when looking at the power/performance ratio

@fred974 Hi !

Do you see anything red in XOA check ? (XOA > Support) ?

(BTW you don't have any backup from XOA ? If you have backup, you can just register a new XOA, connect to you remote and restore everything, it will be much simpler)

If I was in your place, I would do:

• Disconnect all USB used as SR
• Reinstall XCP-ng
• if you have only a few VMs, my option would be just to redeploy XOA, REATTACH the SR (not create, REATTACH, be careful, a create will wipe your disk)
  • Recreate VMs, attach the VDI, boot from here
• if you have to many VM, directly after deploying XOA restore your metadata backup, it should be repluging the SR and create PDB at least (but it's been a while since I didn't use the metadata)

In any case, backup everything, especially the VDI (.vhd). If you have the VDI, you can work around with the rest

@nuentes You can reinstall without wiping the SR. Just plug the ISO, it will ask you if you want a clean install or a reinstall

@AlexanderK You're welcome, i'm happy my tests are useful !

@amititre331 Hi !

Can you try the API request by hand (without ansible) to see if it works ?

Also, do you have any errors when running ansible ?

New version release !

A new patch version of the OME appliance is now available

What I changed:

• Add xen-blkfront and xen-netfront driver
• Add guest tool (so RAM/network is reported, soft shutdown is working)
• /dev/sd* is replaced by /dev/xvd*
• Remove grub password
• Change admin and root password
• SSH is now enabled
• SElinux is working correctly
• DHCP is enabled by default

As usual, please send a DM if you want the link to the vhd

Feedback is welcome !
