** Package changed: ubuntu => kernel-package (Ubuntu)
** Description changed:
Hello,
- We are testing network performance with SR-IOV and bridging on ubuntu
- and security onion in Rhev Hypervisor which is connected to a SuperMicro
- box running T-rex traffic generator on CentOS which is connected to a
- gigmon.
+ We are testing network performance with SR-IOV on ubuntu and security
+ onion in Rhev Hypervisor. We are using a SuperMicro box running T-rex
+ traffic generator on CentOS which is connected to a gigamon to push
+ traffic to the Ubuntu/Security Onion VMs.
The ubuntu 16.04 vm is running on a RHVH host node and is running SR-
- IOV. We have ensured that SR_IOV is enabled in the BIOS. We are finding
- that on security onion that the packets are dropping after a few
- seconds. This is because the interface is going down after a certain
- point. We found that packets are getting dropped as soon as the
- interface shows as down in ip -s link. We are running promiscuous mode
- and it is required for our use case of measuring network traffic. Once
- this process was completed, Kernel 5.3.0-rc3 was built using the 3.2.3
- iavf SR-IOV driver. Note that the i40evf driver was renamed to iavf,
- which is why the name discrepancy exists. After updating the Kernel we
- stopped seeing this issue.

- We were able to perform testing using the 5.3.0 kernel, but long term a
better solution is needed as this would require supporting a modified Linux
kernel with updates, testing, etc.
