Virtio NIC / Ethernet Controller not working with SRIOV

Post by bkannadassan » 2020/07/31 12:36:12

Hi All,

When we have all Virtio port the same works fine and when we have Virtio and SRIOV ports Virtio stops working after sometime. As a part of troubleshooting one option which made the Virtio to work again is when we did rmmod of virtio and modprobe the same started working. This is a VM created via Centos 7.x cloud image in openstack. Please let us know how we should go about debugging the same and what happens when we do rmmod and modprobe and make it work. Any help on the same would be great..
