ice-zc driver error in Rocky Linux 9.2 & 9.3 under XCP-ng 8.2 (Xen) #935

Hi I would like to report issues that I found while using Zero Copy ice device (E810). Informations:

I found Zero Copy working if I used X710 (i40e-zc) under XCP-NG 8.2 and Rocky Linux 9.3 with different server. It is also working just fine if we are not using XCP-NG (no virtualization) under the same machine.

Please find the attached dmesg log of ice-zc and i40e-zc for comparison. ice-zc under Rocky Linux 9.3 i40e-zc under Rocky Linux 9.3

The user found a solution by extending Xen IRQs size from default 64 due to 1024 as this was due to E810 requesting more IRQs.

/opt/xensource/libexec/xen-cmdline --set-xen "extra_guest_irqs=1024"

Please mark this issue as resolved.
