I’ve been asked to compare Ceph with Xostor – has anyone had any experience with either? Are there any comparison tables available?
And does Xostor support data locality?

RE: Loss of connection during an action BUG
@Pilow Il semblerai que j'avais une vm sur le meme réseau (eth0) que le réseau des hotes, se qui devais perturber sans doute le réseau. Du coup a chaque fois que je la redémarais sa faisait déconnecter, mais la je n'arrive plus a répéter le probleme, donc bon pour l'instant je dirai que c'est okay. En tout cas merci

RE: Loss of connection during an action BUG
@Pilow Non les hotre sont en 172.16.20. ect et le xoa en 172.16.10. ect et oui il peuvent bien se ping

RE: Loss of connection during an action BUG
Est que si imaginons mes hote sont sur eth0 et ma vm xoa sur eth1 sa joue ? ou pas

RE: Loss of connection during an action BUG
@Pilow Okay mais cela ne m'avance en rien vue que mes hôte on rejoint le master déjà.

RE: Loss of connection during an action BUG
@Pilow A oui ? Tu peux détailler sur la méthode ?
Et du coup pour en revenir a mon problème de déconnection lors d'une création d'une machine ou autre je ne comprend pas ...

RE: Loss of connection during an action BUG
Et oui il y a bien 3 srv dans le pool

RE: Loss of connection during an action BUG
@Pilow Oui Oui mais la j'avais mis sa pour montrer juste et voir si sa pouvais régler le probleme, mais oui c'est bien le srv 2 le master. Sauf que imaginons le srv2 tombe ba il faut que les autre node soit renseigner pour qu'il puisse prendre le master ?

RE: HOST_NOT_ENOUGH_FREE_MEMORY
@Danp Sorry for the late reply – I was in fits of laughter and completely forgot to ask my question. My question is: when I want to shut down a node with VMs on it, the HA will cause the following:

RE: Loss of connection during an action BUG
@Pilow Désoler de ma réponse tardive, j'étais absent, et oui si je disabled le srv ou le pool est connecter (srv master) :

Voici le réseau si il y a que la que on config :

HOST_NOT_ENOUGH_FREE_MEMORY
I have three nodes; initially, the master was on node one, then I moved it to node two. I set up Xostor storage with one SSD (230 GB) per host, shared across them, containing:


Here are the HA settings for the pool:


The VMs are configured as follows:

Loss of connection during an action BUG
I've got a major bug: whenever I launch or create anything (SR, VM, etc.) or reboot, it logs me out (about half the time), and I can no longer see the VM or anything else.
Et quelque temps apres sa reviens :

RE: Nested virtualization
@MajorP93 I followed your steps exactly:
- Shutdown the VM
- Disabled nested virtualization in Xen Orchestra
- Enabled it again using CLI with:
xe vm-param-set uuid=<UUID> platform:exp-nested-hvm=true - Started the VM again
However, Docker Desktop still shows:
"Virtualization support not detected"At this point, it seems more like a limitation of nested virtualization with Xen/XCP-ng rather than a configuration issue.

RE: Nested virtualization
@MajorP93 I’ve tested everything and restarted the system properly (nested virtualisation enabled, Xen Tools installed, Hyper-V features enabled, full restart), but Docker Desktop still isn’t working.
Systeminfo displays:
‘A hypervisor has been detected’Hyper-V cannot therefore function fully within the virtual machine. It appears that nested virtualisation on XCP-ng (Xen) does not offer full support for Hyper-V, which prevents Docker Desktop from working.
I therefore believe this is a limitation of Xen/XCP-ng, and not a configuration issue.

RE: Nested virtualization
I'm getting back to you. I've enabled ‘Nested virtualisation’, and I've also run the following command in PowerShell within the VM: "dism.exe /online /enable-feature /featurename:Microsoft-Hyper-V-All /all /norestart
dism.exe /online /enable-feature /featurename:VirtualMachinePlatform /all /norestart" in a PowerShell session within the VM, but it still isn’t working. Is this normal? Is Docker not working on Windows under XCP-NG? -
RE: XOSTOR
Well, yes, you had to register with an email address and then update.

Nested virtualization
I was trying to install Docker on Windows, but when I got to the point where I needed to enable virtualisation, I couldn’t do it. Does anyone know why? Here’s what happened:
And I can't turn it on
