ConnectX-6 DX SR-IOV libvirt error

hi,

I’m trying to provide a VF to my instance via libvirt, but I’m getting the following error when I entered the command virsh create instance.xml:

error: internal error: missing IFLA_VF_INFO in netlink response

The MLNX_OFED version I have installed is MLNX_OFED_LINUX-5.5-1.0.3.2.

Please let me know how to mitigate the above error.

Hi bk-2,

Please verify if the libvirt version is 7.1.0 and above. Based on the error string shared, it looks like you are experiencing issue identified as a bug in libvirt that was fixed in following commit —> util: Add phys_port_name support on virPCIGetNetName · libvirt/libvirt@5b1c525 · GitHub

If correct version of libvirt is used on your setup and if this involves further debug, I would like to request opening a support ticket by emailing Networking-support@nvidia.com

Please note a valid support contract is needed for the same. For details on contracts, please feel free to contact our contracts team at Networking-contracts@nvidia.com

Thanks,
Namrata.

Thanks for your reply.

I’ll check it out and bring it here if there are any errors.
