Subject [jira] [Commented] (CLOUDSTACK-6464) [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

    [ https://issues.apache.org/jira/browse/CLOUDSTACK-6464?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14016597#comment-14016597
] 

Marcus Sorensen commented on CLOUDSTACK-6464:
---------------------------------------------

This is a shot in the dark, but there have been some issues around upgrades that involve the
cloud.vlan table expected contents changing. New 4.3 installs using vlan isolation don't seem
to reproduce the issue. I'll see if I can reproduce anything like this with basic and/or non-vlan
isolated upgrades/installs.  Can anyone experiencing an issue look at their database via something
like "select * from cloud.vlan" and look at the vlan_id. If you see something like "untagged"
instead of "vlan://untagged", please try changing it and see if that helps.

I should note as well that it sounds like there might be several different issues represented
here.

>             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

>  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
