    OVM 3.2.7 Virtual Machine guests have high network packet loss

    Hygeia

      Hi,


      I create network using eth7 on OVS, no bond and no VLAN. and then create virtual machine with 2 vnics from this network

      After start VM, there is a high network packet loss.

      Virtual Machine guest is OEL 6.5, has turned off iptables and selinux.

       

      Network configuration is port eth7---Xen Bridge 103ccb410e---Netback (vif47.1, vif47.2)---Netfront( eth1, eth2)
