Konstantin Trushin created CLOUDSTACK-10029:
-----------------------------------------------

             Summary: Virtual Router network interfaces are being constantly added by cloudstack.
                 Key: CLOUDSTACK-10029
                 URL: https://issues.apache.org/jira/browse/CLOUDSTACK-10029
             Project: CloudStack
          Issue Type: Bug
      Security Level: Public (Anyone can view this level - this is the default.)
          Components: cloudstack-agent
    Affects Versions: 4.10.0.0
         Environment: Centos 7 x86_64
            Reporter: Konstantin Trushin


When adding static nat eth interfaces are being added constantly to Virtual Router VM till
they reach PCI slot limit of libvirt. This is caused by public, private and guest interfaces
being marked as untagged and in HashMap and values are overwritten and cleanupNetworkElementCommand
dosn't know nic number in VR VM and constantly adds eth interfaces.

Below is some debugging output:
