LLefuneste replied to the thread Proxmox 9.0 Beta - kernel issues with vfio-pci on Mellanox 100G..I confirm a drastic change in behavior on the way VF passthrough is handled by 6.14.8-2-pve and 6.16.0-50-pve kernels when calling VF passthrough. I have made many tests changing kernel parameters but all comes down to the fact that everything...

LLefuneste replied to the thread Proxmox 9.0 Beta - kernel issues with vfio-pci on Mellanox 100G..So the issue seems to be related to the kernel parameter intremap=no_x2apic_optout which cannot be transposed to 6.14.8-2-pve and 6.16.0-50-pve without causing the passthrough to crash the NIC when calling the VF at start of VM. This kernel...

LLefuneste replied to the thread Proxmox 9.0 Beta - kernel issues with vfio-pci on Mellanox 100G..Unfortunately yes. The link points to latest kernel 6.16.0-50-pve. Exact same behavior than with 6.14.8-2-pve Here is my cmdline : root=ZFS=rpool/ROOT/pve-1 boot=zfs intel_iommu=on iommu=pt intremap=no_x2apic_optout pci_pt_e820_access=on quiet...

LLefuneste replied to the thread Proxmox 9.0 Beta - kernel issues with vfio-pci on Mellanox 100G..Ok Not sure if this is related but I am having a similar and serious issue since I updated to PMX 9. I have drilled down the issue to the kernel version. The issue is definitely present with kernels 6.14.8-2-pve and 6.16.0-50-pve behaving...

just fyi: we're currently looking into this, and believe we have identified a commit (+possible fix) that's responsible, i'll send a patch later if it turns out that it fixes the issue -

I am facing the same issue with intel e810-xxvda4t. Pinned to 6.8.12-11 and working fine now.

I'm running Proxmox on 6 home PCs all with PCIE pass-through. This morning I just updated to the latest kernel and other proxmox updates that were released today. All systems were fine except for one older Pre-Ryzen based PC. The pre-ryzen PC...

LLefuneste replied to the thread Kernel 6.8.12-12-pve Update results in VFIO PCI passthrough issues.Yes exact same issue here once I updated to kernel 6.8.12-12. There definitely is some regression with this kernel version. Several VM on multiple servers give error message when mounting vfio devices at VM start kvm: -device...
