E610-XT4 Hyper-V 2025: Queue Pairs limited to 4 per vPort — Event 280/285

[ReubenTishkoff]

Hi,

I’m using Intel E610-XT4 for OCP 3.0 NICs (8 units total) in a Windows Server 2025 Hyper-V host with a SET Team virtual switch. Driver and firmware are from the official Intel Ethernet Adapter Complete Driver Pack 30.1.1. NVM version is 1.33 (1.21).

⸻

Problem:

Hyper-V constantly logs Event ID 280, saying:

QueuePairs adjusted from requested 16 to actual 4.

This happens for every VM, regardless of the IOVQueuePairsRequested setting, event if I force it to 4.

Additionally, I get Event ID 285 (OID_GEN_STATISTICS timeout) on the host’s vNIC.

⸻

What I’ve tried:
• Applied Set-VMNetworkAdapter -IOVQueuePairsRequested 4 to all VMs
• Disabled RSC on vSwitch
• Firmware and drivers fully up to date

Still, the hardware appears to limit Queue Pairs per vPort to 4, while similar Intel NICs like X710 do not.

⸻

Questions:
1. Is this limitation expected on the E610-XT4 under Hyper-V 2022/2025?
2. Will there be a firmware or driver update to allow more QPs per vPort?
3. Is this card certified for Hyper-V SET scenarios?

I’ve attached screenshots of NVM version and both warnings. Thanks in advance!

Best regards,
