Evan McGee commented on CLOUDSTACK-6464:
----------------------------------------
Just a +1 bump on this. It seems like a fairly large regression for anyone
using traffic labels in KVM to lose all egress connectivity. Could someone with
more knowledge of the commit that caused this weigh in?
> [KVM:basic zone- upgrade to 4.3],after any vm restart,all the nics are
> plugged to default bridge even though trafiic labels are being used

> 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: 4.3.1
>
>
> 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
