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 ? net_vdev_netvsc: probably using routed NetVSC interface "s1p0" (index 8) tap_nl_dump_ext_ack(): Cannot delete qdisc with handle of zero tap_nl_dump_ext_ack(): Failed to find qdisc with specified classid tap_nl_dump_ext_ack(): Failed to find qdisc with specified classid tap_nl_dump_ext_ack(): Failed to find qdisc with specified classid tap_nl_dump_ext_ack(): Failed to find qdisc with specified classid tap_nl_dump_ext_ack(): Failed to find qdisc with specified classid tap_nl_dump_ext_ack(): Failed to find qdisc with specified classid tap_nl_dump_ext_ack(): Failed to find qdisc with specified classid tap_nl_dump_ext_ack(): Failed to find qdisc with specified classid net_vdev_netvsc: probably using routed NetVSC interface "s0p0" (index 7) tap_nl_dump_ext_ack(): Cannot delete qdisc with handle of zero tap_nl_dump_ext_ack(): Failed to find qdisc with specified classid tap_nl_dump_ext_ack(): Failed to find qdisc with specified classid tap_nl_dump_ext_ack(): Failed to find qdisc with specified classid tap_nl_dump_ext_ack(): Failed to find qdisc with specified classid tap_nl_dump_ext_ack(): Failed to find qdisc with specified classid tap_nl_dump_ext_ack(): Failed to find qdisc with specified classid tap_nl_dump_ext_ack(): Failed to find qdisc with specified classid tap_nl_dump_ext_ack(): Failed to find qdisc with specified classid Thanks, Raghava Dattu. -----Original Message----- From: Stephen Hemminger <[email protected]> Sent: Wednesday, October 12, 2022 10:41 PM To: Dattu Gundu <[email protected]> Cc: [email protected] Subject: Re: [External] : Re: qdisc errors on Azure VM (TAP Config) On Wed, 12 Oct 2022 11:14:50 +0000 Dattu Gundu <[email protected]> wrote: > Hi Stephen, > > Attached is the configuration params copied in the text file. > Please let me know your pointers on the same. 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.
