    Ping destination unreachable from OVM Host to guest

    NotSteven
      Hello,

      I currently have an OVM guest running with Oracle Linux 6 but I'm unable to ping from this guest to the OVM Server host. A VNIC has been created in OVM Manager and it has been assigned to my guest.
      However when I try to ping from the OVM host to the ip address of my guest i get destination host unreachable error.

      (the guest has a static ip)
      [root@lnx-iaovm01 scripts]# ping 10.0.2.80
      PING 10.0.2.80 (10.0.2.80) 56(84) bytes of data.
      From 10.0.2.76 icmp_seq=2 Destination Host Unreachable


      network-bridge status on ovm host:

      [root@lnx-iaovm01 scripts]# ./network-bridge status

      I'm sure you'll need additional info but I'm not sure which info to supply.
      Feel free to query.
