Subject [jira] [Commented] (CLOUDSTACK-361) Wrong creation of guest networks on a KVM host in Multiple Physical Networks with guest traffic
Date Tue, 16 Oct 2012 20:03:03 GMT

    [ https://issues.apache.org/jira/browse/CLOUDSTACK-361?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13477298#comment-13477298

Prasanna Santhanam commented on CLOUDSTACK-361:
-----------------------------------------------

Looks like KVM multiple guests on multiple phy.nets is not supported in 4.0

>                 Key: CLOUDSTACK-361
>                 URL: https://issues.apache.org/jira/browse/CLOUDSTACK-361
>             Project: CloudStack
>          Issue Type: Bug
>          Components: Management Server
>    Affects Versions: pre-4.0.0
>            Reporter: Chandan Purushothama
>             Fix For: pre-4.0.0
>
>
> ================
> Steps to Reproduce:
> ================
> 1. Deploy an Advanced Zone Setup with Two Physical Networks and Ubuntu 12.04 KVM Host.
> 2. Physical Network 1 carries management, storage, guest and public Traffic while Physical
Network 2 carries guest traffic only.
> 3. On Physical Network 1, provide the KVM Labels for all the traffic types such that
they refer to the asfbr0 (bridge on KVM Host) while on Physical Network 2, provide the KVM
Labels for the guest traffic type such that they refer to the asfbr1 (bridge on KVM Host)
> 4. Create the corresponding bridges on the Ubuntu 12.04 KVM Host which has two physical
nics.
> bridge name     bridge id               STP enabled     interfaces
> asfbr0          8000.bc305bd41c36       no              eth0
> asfbr1          8000.bc305bd41c37       no              eth1
> 5. Add the host to the Setup.
> 6. Create tags to the guest traffics of the physical networks 
> 7. Create Two Network Offerings with the corresponding tags given for the guest traffics.
> 8. Create two networks using the two network offerings and deploy a VM on it.
> 9. Observe the KVM host bridges information and notice the wrong creation of the guest
networks.
> ============
> Observations:
> ============
> **Note that the Management Server mentioned that the VLAN be created on asfbr1 bridge
to which eth1 is plugged into**
