    @leroyj We already know that our k10temp module doesn't have support beyond Zen 2, and needs to be updated. That's not incredibly complex, but still needs to be done. I was wondering if the amd cpu temp be probed the way you did for the intel cpu. No, AMD temperature infos are not exposed through MSR but through PCIe/MMIO (through various subsystems, like "SMU" and other ones). Like what does https://github.com/torvalds/linux/blob/master/drivers/hwmon/k10temp.c or https://github.com/ocerman/zenpower. (regarding the AI draft, there is no documented MSR 0xc0010292 in neither APM nor public Zen3 PPM) That doesn't require any specific Xen support aside the right Linux drivers in Dom0.

    @poddingue Thanks for taking a look. Yes it is this part that tells me that it should start the VM automatically once the import has completed. "After the transfer, the VM on XCP-ng side is started:" Followed by, "This process is fully automated, without any human intervention after it starts on step 1." [image: image.jpeg] https://docs.xcp-ng.org/installation/migrate-to-xcp-ng/ But my findings/experience is that the VM does not start once the import/transfer has completed. So either the docs are wrong. Or the function is not behaving as intended. I'm acctually fine either way. As long as I know what to expect. However, I would like to have it auto-start the VMs after transfer completion. Which would make the procedure "Fully automated". Update: Am I assuming correctly that "the XO V2V guide says to start the VM yourself once the migration is complete " you're reffering to, is part of the "test migration"-procedure? Not the acctual production mgiration? Because: "Final migration Run the production migration When you're ready for the final migration: Shut down the source VM completely. Start the V2V migration in Xen Orchestra with the Stop source option enabled. This ensures the final sync happens while the VM is powered off, and prevents any inconsistencies." In my mind doesn't state that the VM should be started manually post-transfer. Great thanks in advance for discussing! Cheers!

    @carloum70 said: @john.c We are using a LCAP bond. For my understanding, if I remove the IP settings from eth4, the problem will still not be solved because of the known issue with the bond that you explained in “Weak Host Model & HA Heartbeat Failures.” (At the moment we have HA disabled.) What use is eth4 put to is it still management, if so put it into bond0? In one of my earlier posts on this I also detailed how to in the meantime use sysctl to force strong host, but best to wait for the official update from Vates.

    @poddingue Turns out it is all secondary-to-secondary out of sync. So that makes it less intense, though if primary dies I wonder how it will resolve this, or if it will become split brained. Still unsure of how it happened, but the ones I manually cleaned up have not come back. Going to continue to manually clear them up. If it happens again I will have an alert setup to notify me, and I have all the xcp-ng logs and everything to be able to see what happened. If that happens I will post here with details and logs for the resource so we can see how it occurs. [image: image.jpeg]

    @AtaxyaNetwork Merci pour tes recherches ! Oui "cd_label" serait cool comme ajout au plugin ce qui permet sur les distro type Fedora/Redhat de ne pas avoir de boot_command à gérer
