newplan

    hello ,i'm now confused with enabling VFs with 82599ES-SR2 ,my OS is ubuntu 14.04(64 bit)

    i have intsall some drives like ixgbe(4.12) and ixgbevf(2.16)(update to the latest version).

    i'm sure about having eabling the vt-x and vt-d in bios ,and having conformed that the system support SR-IOV (by order lspci -vvk -s 02:00.0 | grep SR-IOV)

    while i enable vfs ,it failed , i'm hoping for some further solutions.(my eamils is enwplan001@163.com)
