XCP-ng 8.3 betas and RCs feedback 🚀

I think yes, but probably need some tinkering in the USB script filtering some devices for security reasons. It's documented: https://docs.xcp-ng.org/compute/#passing-through-keyboards-and-mice

@olivierlambert ok thanks

Is there a way to track the progress of applying patches to a host? I'm updating the master of one of my pools and it dropped out of XO and hasn't come back yet. I don't recall applying patches to take this long normally.
-
Yes, you can check the yum history for example, eg
yum history list -
@olivierlambert I'm seeing 27 EE which seems to indicate that it worked but there was an error?
I have had XO display errors when performing updates but there's currently nothing in the logs and the pool still isn't showing up.
Using yum history info it appears to output EE whenever the scriptlet has an output. In this case it returned ok and I also have lines regarding disabling the repos.
Now I'm getting UND_ERR_SOCKET as an error on the Servers page. If I disable and then enable the server, I get write ECONNRESET.

:Optional package
- kernel-alt-4.19.316+1-2.xcpng8.3: Enable CONFIG_X86_AMD_PLATFORM_DEVICE in kernel config
I see some mentions of this option in relation to fan speeds.
But what is the status on AMD support in general?
I have a recent AMD platform, and from what i can see a lot has been added for AMD support in the past few kernel versions.
Particularly in relation to power management.I did a purely unscientific test and booted a ubuntu 24.04 live cd on my XCP-NG server, and the power consumption was 10-15% lower at similar load level, compared to XCP-NG.
Is the hardware support for e.g. power management handled by the kernel in dom0 or by Xen?
What are the current plans for a more recent kernel for dom0 - i have not seen anything on kernel version plans for a long time?
Keep up the good work

:Is the hardware support for e.g. power management handled by the kernel in dom0 or by Xen?
It's a very complex question where there's no definite answer. But to answer your question, yes, XCP-ng 9 will have a recent kernel, providing many benefits for I/O and potentially power usage.

@CJ it may be that XAPI or stunnel failed to fully start.
Check:
systemctl status xapi-wait-init-complete.service systemctl status stunnel@xapi.service -
@stormi wait init shows exited with a success status. stunnel shows active and running.
I disabled the server and enabled it again and this time it connected without an error. However, it lists as unknown pool and doesn't show in any of the host/pool/vm pages.
Also, when I go on the console, it states that the host is already in maintenance mode. Selecting Enter/Exit Maint Mode results in the following.
(''NoneType' object has no attribute 'opaqueRef'') -
Is it known GPU passthrough dont work in 8.3 RC1 ?
i did the setup now through xen-orchestra and see it in windows but no matter what i do it keeps giving error code 43 -
@marvine I dont know if that is true or not.. I am using 8.3 RC1 with GPU pass-through to NVidia Tesla cards with no problems (aside from the NVidia drivers being a pain in the backside to install under Linux).

:giving error code 43
This error is a driver issue on Windows side.
It says that the card is "virtualised" Nvidia is very strong in blocking this, if it's not allowed.
If you google for it there should be plenty of workarounds.
-
@Houbsi yeah i did try it with the nvcleaninstall but gives me the same error and also tried the HV value to hide windows is virtualised.
Will try again to remove everything and start over
-
@marvine I am using two Nvidia P40 with passthrough to Debian VMs with XCP-ng 8.3 RC1. I had no issues with passthrough, installing and runing the P40. For Windows VMs, this older post might give some more information.

(''NoneType' object has no attribute 'opaqueRef'')Have you tried to reboot the server once again? If the issue persists, can you share
/var/log/xensource.logsomewhere (might contain sensitive information, so better share privately). -
@stormi I have not rebooted the server at all. I told it to apply patches and then this all happened.
I didn't want to reboot it in case it was in the middle of something or if there were things you wanted me to check.
I'll try rebooting it and see what happens. Hopefully the other pools and nodes won't have this issue.
-
This will be fun. The console keeps losing connectivity with the VMs so I wasn't able to suspend them before rebooting the server.
Oh, that's not good. No change after rebooting. It's still borked. What's the best way to reach out to you, @stormi ?
-
@CJ You can send me a PM here.
-
@stormi Uh, how do I do that?
Also, I think the problem may be due to when I was attempting to set up a private network. I had deleted all of that but it seems to be stuck in a loop trying to find sdn-controller-ca.pem. Therefore the update never completes and it just tries again.
