------------------------------------------

             Summary: problem adding new shared network NIC to VM "A NIC with this MAC address exits for network:"
                 Key: CLOUDSTACK-10350
                 URL: https://issues.apache.org/jira/browse/CLOUDSTACK-10350
             Project: CloudStack
          Issue Type: Bug
      Security Level: Public (Anyone can view this level - this is the default.)
          Components: Network Devices
    Affects Versions: 4.11.0.0
            Reporter: Stephan Seitz
         Attachments: cloudstack-4.11.0-stephans-duplicate-nicaddress-fix.diff

{color:#4c4c4c}After upgrading a working 4.9.2 setup to 4.11.0.0 we've noticed that we're unable to add a NIC (shared network) to a running VM via GUI.{color}
{color:#4c4c4c}The Error is "A NIC with this MAC address exits for network: (uuid of the current (other NIC) network)"{color}
{color:#4c4c4c}Using cloudmonkey and giving a self-computed MAC-address does not rise the error and works as expected.{color}

{color:#4c4c4c}After digging into the code, I think I've found the problem, but am too bad in java to provide a sustainable fix.{color}

{color:#4c4c4c}I've attached a patch which obviously (with own manual tests) fixes that issue by simply commenting out the respective codeblock.{color}

{color:#4c4c4c}As far as I dug into the code, the third parameter of NicProfile is handled by {color}

{color:#4c4c4c}NetUtils.long2Mac(NetUtils.createSequenceBasedMacAddress(ipVO.getMacAddress(), NetworkModel.MACIdentifier.value()){color}

{color:#4c4c4c}inside{color}

{color:#4c4c4c}NicProfileHelperImpl.java{color}

{color:#4c4c4c}I assume createSequenceBasedMacAddress can handle null as MAC, but doesn't get called at all if {color}


{color:#4c4c4c}_nicDao.findByNetworkIdAndMacAddress(networkId, macAddress) results != null if macAddress is null.{color}
