That's weird. Adding @Team-XO-Backend in the loop including @julienxovates

Yes it's for this summer, can't tell more precisely (because I don't know ^^)

Ah excellente nouvelle Je passe le sujet en résolu !

Ping @julienxovates

@psafont Thank you for the quick response. I also found a similar issue: the other-config:auto-scan=true parameter is not being applied during xe sr-create either. As with the name-description parameter, the workaround is to add it separately afterwards using xe sr-param-add.

Dug a little deeper. For a VM where the disks are not shown the following XO API call fails: /rest/v0/vms/a519e879-3971-9210-51b6-7df14336e7b7/vdis { "error": "no such VDI ac37700d-3157-4df7-b8e8-e1799a994591", "data": { "id": "ac37700d-3157-4df7-b8e8-e1799a994591", "type": [ "VDI" ] } } Also the VDI cannot be retrieved over the XO API: /rest/v0/vms/a519e879-3971-9210-51b6-7df14336e7b7 ...

Thanks for the ping and for narrowing it down; that live-migration repro is a really useful signal. I don't know enough about how the guest tools report IPs back through XAPI to say where the canonicalisation should happen, but it sounds like something @Team-Hypervisor-Kernel might want to look at since the trigger is on the agent side after migration. If it turns out to be reproducible on another Windows guest version (2022, 2019), that might help narrow it further; no pressure though, you've already done the hard part.

Hi @maximsachs, Sorry for the delay. From what you describe, the driver seems to be probed in all cases but I have a doubt regarding the driver from xcp-ng 8.2. I rebuilt it specifically for 8.3. To completely eliminate a driver issue, can you try this RPM ? From the host, this can be done by running the following commands: $ wget https://nextcloud.vates.tech/public.php/dav/files/R33Dwpt5gjy6CCr/broadcom-bnxt-en-1.10.0_216.0.119.1-1.0.82srcs.0.xcpng8.3.x86_64.rpm $ yum update ./broadcom-bnxt-en-1.10.0_216.0.119.1-1.0.82srcs.0.xcpng8.3.x86_64.rpm Also, since this xcpng-8.2 release seems to have support for device IDs that have been removed from the 8.3 one, can you give the output of the following shell commands: $ lspci -nn -s 0001:86:00.0 and $ lspci -nn -s 0001:86:00.1 Regards, Thierry
