@laszlobortel We concluded that older Linux kernels plus live migrations plus lvmohba storage seems to trigger the issue. Our workaround was to upgrade to a mainline 6.x kernel packaged by ElRepo https://elrepo.org/wiki/doku.php?id=start for Rocky 8 systems that were especially prone to the CPU hang. The kernel upgrades effectively stopped the issue from occurring.

Good to hear, thanks a lot for your feedback.

The rule is oddly written, and may conflict with another similar one that already exist in the distro (hence may not be useful to begin with). The modern generic rule for doing vCPU hotplug is, which would be preferable to the current z10-xen-vcpu-hotplug.rules. ACTION=="add", SUBSYSTEM=="cpu", ATTR{online}=="0", ATTR{online}="1"

Hi @pierrebrunet. I have deleted the "parentless" VDIs and snapshots. So the "Unhealthy VDI" page is empty for me. So everytime I retry with the VM in question it is creating a new (full) backup-chain. Regards, Marc

I showed my boss XCP-ng because it looks a lot like ESXi. He looked into the software and asked why XO lite has been "coming soon" for 5 years now. What should I tell him? It may be help to actually look at Xen Orchestra as XO Lite is targeted at basic functions. Anyway network creation is present in Xen Orchestra 5 and/or 6. Maybe more extensive, but will allow for better ACL (via RBAC) capabilities. https://docs.xen-orchestra.com/xo5/sdn_controller#network-creation The pieces are coming together it’s a new software XO Lite, the teams at Vates are growing more of XO Lite is being developed and tested. Though Xen Orchestra is a more suitable base for a business environment, with multiple departments and teams, due to XO Lite only using and allowing the use of root account authentication. The root account of XO Lite refers to the XCP-ng host server administrator account - full access!

@poddingue My colleage managed to workaround the issue by re-installing the lab on other hardware, I think it is now Cisco UCS-servers. It was HP ProLiant-servers before. Maybe it was an issue with some of the NIC or firmware, im not really sure, but it works now.
