---------------------------------------
Hi
Issue still here... Cloudstack ver 4.4.2, VR ver 4.4.1, clean install, new
instance with default network offering : default isolated with source nat. Just
after VR goes up a host logs in and adds another public interface with the same
ip and same mac as 1st public interface ( eth2 ) :
root@r-28-VM:~# cat /etc/network/interfaces
auto lo eth0 eth1 eth2
iface lo inet loopback
iface eth0 inet static
address 172.17.150.1
netmask 255.255.255.0
iface eth1 inet static
address 169.254.1.48
netmask 255.255.0.0
iface eth2 inet static <<<<< public iface
address 185.22.***.***
netmask 255.255.255.0
root@r-28-VM:~# cat /var/log/auth.log | grep eth3
Apr 25 20:00:50 r-28-VM sudo: root : TTY=unknown ; PWD=/root ; USER=root ;
COMMAND=/sbin/ip link show eth3
Apr 25 20:00:50 r-28-VM sudo: root : TTY=unknown ; PWD=/root ; USER=root ;
COMMAND=/sbin/ip addr add dev eth3 185.22.***.***/24 brd +
And after that all iptables rules are based on this eth3
Looks like Cloudstack doesnt know that VR already has public iface assigned and
he logs in to create it and all iptables rules.

> Key: CLOUDSTACK-6464
> URL: https://issues.apache.org/jira/browse/CLOUDSTACK-6464
> Project: CloudStack
> Issue Type: Bug
> Security Level: Public(Anyone can view this level - this is the
> default.)
> Components: Management Server
> Affects Versions: 4.3.0
> Reporter: sadhu suresh
> Priority: Critical
> Fix For: 4.4.0, 4.3.1
>
>
> Steps:
> 1. create a KVM basic zone with 2 nics on host (pre 4.3 build)
> 2.use cloudbr0 for management and cloudbr1 for guest by specifying the
> traffic labels in the physical networks.
> 3.deploy few vms
> 4.upgrade to felton GA build as per the Upgrade instructions.
> actual result:
> Upgrade successful but all the vnets that were attached to cloudbr1 before
> upgrade are attached to cloudbr0.
> Due to this network connectivity is lost.
> Expected result:
> Even after upgrade ,all the vnets should be attached to the same bridge as
> before upgrade.
> ex:
> before Upgrade : this vms(i-5-616-VM) nic was attached to cloudbr1 and after
> upgrade and VM stop/start.
> the network rules are getting programmed in cloudbr0 .check below output
