<![CDATA[SR-IOV and Proxmox reset_hw() failure: Reset Failed!]]>So I'm trying to evaluate SR-IOV on a test server (Dell R620, dual E5-2670v2, SR-IOV, VT-D, etc all enabled) and everything works on a Linux guest, but I'm getting the following error whenever I attempt to boot up a pfSense guest.

The NIC is an Intel X520 based Dell rNDC, and AFAIK is fully functional and supported by SR-IOV and Proxmox.

Is this a known issue in Proxmox? A known issue with pfSense? A configuration mistake I've made somewhere? Please advise.

The following is the error I get on pfSense:

ixv0: <Intel(R) X520 82599 Virtual Function> mem 0x1000004000-0x1000007fff,0x1000000000-0x1000003fff at device 0.0 on pci1

I've reproduced it on pfSense 2.7.2 and Proxmox 8.1.4.
