https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=222996 --- Comment #23 from Michael <michael.adm@gmail.com> --- Passthrough Intel X710 in Windows 2019 Gen2 Hyper-V guest Freebsd-CURRENT works, but not as we would like. Action roadmap: 1. disable the necessary adapter in the Device Manager 2. Add adapter to R03 VM $MyEth = Get-PnpDevice -PresentOnly | Where-Object {$_.Class -eq "Net"} | Where-Object {$_.Status -eq "Error"} $DataOfNetToDDismount = Get-PnpDeviceProperty DEVPKEY_Device_LocationPaths -InstanceId $MyEth[0].InstanceId $locationpath = ($DataOfNetToDDismount).data[0] Dismount-VmHostAssignableDevice -locationpath $locationpath -force Get-VMHostAssignableDevice Add-VMAssignableDevice -LocationPath $locationpath -VMName R03 R03 dmesg: pcib0: <Hyper-V PCI Express Pass Through> on vmbus0 pci0: <PCI bus> on pcib0 ixl0: <Intel(R) Ethernet Controller X710 for 10GbE SFP+ - 2.1.0-k> at device 0.0 on pci0 ixl0: fw 5.40.47690 api 1.5 nvm 5.40 etid 80002d35 oem 1.264.0 ixl0: PF-ID[1]: VFs 64, MSI-X 129, VF MSI-X 5, QPs 768, I2C ixl0: Using 1024 TX descriptors and 1024 RX descriptors ixl0: queue equality override not set, capping rx_queues at 4 and tx_queues at 4 ixl0: Using 4 RX queues 4 TX queues ixl0: Using MSI-X interrupts with 5 vectors ixl0: Ethernet address: 3c:fd:fe:21:02:e2 ixl0: Allocating 4 queues for PF LAN VSI; 4 queues active ixl0: PCI Express Bus: Speed 8.0GT/s Width x8 ixl0: Failed to initialize SR-IOV (error=2) ixl0: netmap queues/slots: TX 4/1024, RX 4/1024 ixl0: Link is up, 10 Gbps Full Duplex, Requested FEC: None, Negotiated FEC: None, Autoneg: False, Flow Control: Full ixl0: link state changed to UP 3.

Live migration is one of the cornerstones of virtualization. And what threatens, for normal functioning, an error message: ixl0: Failed to initialize SR-IOV (error=2) -- You are receiving this mail because: You are the assignee for the bug.help
