Hi Stephen,
As Microsoft recommended in the below link to use the failsafe PMD in the AZURE.
-----------------------------------------------------------------------------------------------------------------
https://learn.microsoft.com/en-us/azure/virtual-network/setup-dpdk#failsafe-pmd
So, we are using the failsafe/tap/vdev_netvsc in AZURE cloud VM's.
-----------------------------------------------------------------------------------------------------------------
Am I referring to the old link ?
Is there any further update from Microsoft on the recommended PMD on AZURE? Did I miss any?
It would be helpful if you share any pointers to the same ?
Actually, we don't have any functional issues.
Also, the below errors are not a big problem for us.
But only request is do we have any way to suppress them ?

Config looks like it should work.
Why are you not using the native netvsc PMD instead?
Failsafe/Tap/vdev_netvsc is excessively complex, and is slower.
