No LXC Container Doesn't Want to Start

[Blais]

Hello, hello.

After a return from AMD's RMA, I just relaunched the server. I made an update to Proxmox. Then I reconnected as before.
I have a pci passthrough for a network card for the firewall, in short, I have no problem for VMs unlike LXC containers.

Here is an extract by inserting the flag --logfile

Thank you for helping me understand what's going on and enlighten me towards a possible solution.

please include the container config file, and a full debug log (https://pve.proxmox.com/pve-docs/pv...ontainers_with_span_class_monospaced_pct_span)

Hello and thank you for your response.

I modified the grub command, put an isolcpu, and amd_iommu=on iommu=pt that I deleted.

I relaunched the machine and miraculously, the containers were able to start. I don't understand what broke the LXC because it worked before.

Another thing, which has nothing to do with it, but npt's KVM bug seems to have found a solution: https://patchwork.kernel.org/patch/10027525/

Will you apply it very soon?

Personally, I recompiled the kernel pve with the patch and the passthrough gpu gives very good performances.

It was just in case.

Other than that, thank you very much.
