March 18, 20215 yr I'm very sorry, my English is not good has been normally turned on SRIOV through the command, and the VF network card can also be seen in the system equipment, but it is not displayed in the virtual machine Unraid OS kernel /bzimage append intel_iommu=pt vifo-pci.ids=8086:10c9 initrd=/bzroot //[/boot/config/go] #!/bin/bash # Start the Management Utility /usr/local/sbin/emhttp & sudo echo 7 > /sys/class/net/eth1/device/sriov_numvfs xml addition can be used normally <hostdev mode='subsystem' type='pci' managed='yes'> <source> <address domain='0x0000' bus='0x03' slot='0x10' function='0x3'/> </source> <address type='pci' domain='0x0000' bus='0x00' slot='0x08' function='0x0'/> </hostdev>
March 18, 20215 yr I do not have any experience with SRIOV, but it is discussed over Here: https://forums.unraid.net/topic/103323-how-to-using-sr-iov-in-unraid-with-1gb10gb40gb-network-interface-cards-nics/ The problem is that Unraid binds devices to vfio-pci very early in the boot process, so by the time you enable SRIOV it is already done. Try adjusting your go script like this: #!/bin/bash # enable SRIOV and process vfio-pci binding again echo 7 > /sys/class/net/eth1/device/sriov_numvfs /usr/local/sbin/vfio-pci >>/var/log/vfio-pci # Start the Management Utility /usr/local/sbin/emhttp & With this change, Unraid will re-process the vfio-pci bindings after running your SRIOV command. I recommend doing both of these BEFORE starting emhttp so everything will be in place before the array starts. Also, I'd recommend removing the `vfio-pci.ids-808:10c9` param from your syslinux. It is better to manage that from System Devices rather than in syslinux. Please post your diagnostics (Tools -> Diagnostics) after doing this Note: it is probably a good idea to stop the array and disable array autostart (Settings -> Disk Settings -> Enable auto start = no) before making these changes, that way if the system has problems you can power it down and edit the files again without worrying about an unclean shutdown.
March 19, 20215 yr Author @ljm42thank you the network.cfg file is like this, sriov cannot be used normally /boot/config/network.cfg # Generated settings: IFNAME[0]="br0" DHCP_KEEPRESOLV="no" DHCP6_KEEPRESOLV="no" BRNAME[0]="br0" BRNICS[0]="eth0" BRSTP[0]="no" BRFD[0]="0" DESCRIPTION[0]="unraid" PROTOCOL[0]="ipv4+ipv6" USE_DHCP[0]="yes" USE_DHCP6[0]="yes" METRIC6[0]="0" PRIVACY6[0]="0" IFNAME[1]="eth1" PROTOCOL[1]="ipv4+ipv6" USE_DHCP[1]="yes" USE_DHCP6[1]="yes" PRIVACY6[1]="0" SYSNICS="2" Only show one network card If the network.cfg file is like this, # Generated settings: IFNAME[0]="br0" DHCP_KEEPRESOLV="no" DHCP6_KEEPRESOLV="no" BRNAME[0]="br0" BRNICS[0]="eth0" BRSTP[0]="no" BRFD[0]="0" DESCRIPTION[0]="unraid" PROTOCOL[0]="ipv4+ipv6" USE_DHCP[0]="yes" USE_DHCP6[0]="yes" METRIC6[0]="0" PRIVACY6[0]="0" SYSNICS="1" After adjusting the go script, the network card is displayed, but other problems have occurred #!/bin/bash # enable SRIOV and process vfio-pci binding again echo 7 > /sys/class/net/eth1/device/sriov_numvfs /usr/local/sbin/vfio-pci >>/var/log/vfio-pci # Start the Management Utility /usr/local/sbin/emhttp & Network Settings-eth1 prot down The default port is closed after booting, you need to click to open it, the virtual network card can be used normally Can I add a user script to open the port? After manually clicking, the virtual machine can't get the network normally. You can only get the network normally by restarting the virtual machine or disabling the network card, and then opening it Adding user script can solve this problem. Is there a better way? Or can it be added to the go script? #!/bin/bash ifconfig eth1 up tower-diagnostics-20210319-1023.zip Edited March 19, 20215 yr by s1oz
March 19, 20215 yr Just to be clear, I have never worked on something like this before But if this solves the problem: ifconfig eth1 up then I would add it to the go script after vfio-pci but before emhttp. i.e. you want to call this after the network cards are setup but before plugins are installed, the array starts up, etc. And all that is started by emhttp. User scripts are for things that need to be run after the array has started. It looks like you have added some more to your go script: ip link set eth1 vf 0 mac 00:25:8b:03:10:01 ip link set eth1 vf 1 mac 00:25:8b:03:10:03 ... Is that related to the NICs that you bound to vfio-pci? If so I'd think these lines should come before the call to vfio-pci. But I don't really know.
