I've taken a quick look, looks like it'll be solved as part of the Windows guest agent overhaul, so please look forward to that.

@abudef An overhaul of the guest agent is coming. We're considering adding some kind of update notifications as part of that overhaul, but it'll take some time to suss out the details. Autoupdating the Xen drivers is potentially disruptive and I'd prefer avoiding outages arising from an update coming at a bad time.

i2c error seems related to (I guess) a RGB controller that is presumably controlled by something else (or maybe not usable/non plugged). But it's harmless unless you are looking to configure RGB (but I don't think you want to do that anyway).

EFI_MEMMAP warning is probably because Dom0 doesn't see UEFI mappings, as it relies on a different method to do UEFI calls. This is expected and this warning doesn't indicate a problem.

The latest error is likely related to the first one.

what I will miss /won't be able to do vs a user that has not these messages? (otherwise, why they would be raised)

Nothing meaningful.

if these messages /failures have an impact on the time during which the machine is booting? (it seems the load process is hanging for about a minute)

No.

if these messages /failures are officially documented somewhere?

For the EFI_MEMMAP, XenServer has a article on it stating the same as me : https://support.citrix.com/external/article/CTX331542/citrix-hypervisor-82-efi-efimemmap-is-n.html

how can I resolve these failures, because failures are failures... even if "one should not worry about them"?

You may be able to hide it, like by blacklisting i2c and such, but TBF it's not worth the time.

@taghjichte A PCI card should be more reliable than an USB card in most cases. Do you have realtime/low latency audio requirements or is it simply for normal playback (music etc)? Virtualization will work fine for typical playback but for low latency, you might want some specific tuning. Also, you might want to test DPC latencies with the Xen drivers when there's I/O activity.

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
