No. There is no reason to use failsave if you you use tne native netvsc PMD. Netvsc PMD has internal support for the accelerated SRIOV path. > Question2: Is there any alternatives on Azure cloud ?

Plead post full kernel config for your custom kernel, You will need the multi-queue prio qdisc to get the interface to TAP working.
