I just received new hardware to build new PVE cluster and I faced an issue with intel E810 driver (ice). As i googled, this issue related only system with large CPU number.
Here is error
[258314.532279] ice 0000:63:00.1: The DDP package was successfully loaded: ICE OS Default Package version
[258314.533037] ice 0000:63:00.1: not enough device MSI-X vectors. requested = 257, available = 256

[258314.544696] ice: probe of 0000:63:00.1 failed with error -5

And CPU on server

Now I found a temporary fix, just limited number of CPUs with `maxxpus=252` in grub params and driver loaded successfully.

Here is corresponding bug with fix in ubuntu kernels https://bugs.launchpad.net/ubuntu/+source/linux/+bug/2012335

I guess this fix should be ported to pve kernels too.

Upd: tested with pve kernel 6.2 and ice driver successfully loads
