------------------------------------------
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}
