Thank you for the post. Can you help alos by providing what is the network adapter model used here? And the operating system?
I will further check for you. Thanks.
Network adapter model is Intel 82599 10 Gigabit NIC, OS is both Centos 7 & Ubuntu 14.04.
Thank you for the info. Would you help clarify which OS is the host OS and the guest OS? What are the kernel versions?
For the Intel 82599 10 Gigabit NIC, is it an onboard NIC or X520 series network adapter? Please refer to this site for the model. ARK | Compare Intel® Products
