Hi, Guys: I have developed a VM to use SRIOV VF of DPDK2.1 libraryand its PF NIC is interl X552 NIC. The VM is deployed on KVM on Linux box. NIC Inforoot at localhost:~# modinfo ixgbe filename:?????? /lib/modules/3.14.49-rt46-WR7.0.0.5_ovp/kernel/drivers/juniper/x552-nic/ixgbe.ko version:??????? 4.2.0.4.1-unreleased license:???????

By the way, the SRIOV of this VM work fine for X550 NIC and? 82580 NIC, Thanks.
