Comment 2 for bug 1822263

Hi Alexander,

I have tried to reproduce the issue on our environment but the VM rebooted many times without errors.
But during an examination of customers logs, some errors were observed. Let's try the next steps to resolve the issue:

1) Recently we have updated i40e drivers to the 2.7.29 version - https://review.fuel-infra.org/#/c/40697/ . Is issue reproduced with them?

2) Could you please check that next recommendation from XL710 configuration guide fulfilled:

The VF driver automatically loads in the host operating system as soon as the VFs are created by
the PF driver. The VF driver claims newly-created VFs, and these VF are not available for Virtual
Machine (VM) assignment. There are two methods to overcome this scenario:
a. Unload the VF driver from within host operating systems by executing the following command in
Linux terminal with superuser (root) permission.
#rmmod i40evf
b. Blacklist VF driver by adding blacklist i40evf to the /lib/modprobe.d/dist-blacklist file

3) I the dmesg logs of the compute instance the next error observed "Unable to send opcode 2 to PF, err I40E_ERR_QUEUE_EMPTY, aq_err OK".

Did this error persist after doing paragraphs 1 and 2?
