    @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!

    @tjkreidl said: @john.c Interesting information about the strong v. weak host model. Active-active and LACP bonds will split the network traffic between the NICs, while an active-passive bond only uses the primary. WHat type of bonds do you have set up? It’s from analysis of the posts above and digging into the networking stack of the Linux kernel, I’d also noticed this myself through bonding ports of my setup, into a similar network setup, then suddenly getting this kind of event, everything is setup correctly, but it’s the packets going out on the wrong networks as packet flow analysis monitoring, via special monitoring modules made for OpenMetrics revealed. Essentially using similar methods to tracing unauthorised connections or studying how water and air behaves. But in this case understanding why and how the packets weren’t travelling where they should be and thus at times not reaching the specific destination they should on the particular port.

    @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
