Thanks, -----Original Message----- From: Bjoern Teipel [mailto:[email protected]] Sent: 03 April 2013 20:41 To: [email protected] Subject: Re: VLAN traffic not seen by System Router Well it's quite difficult to debug your issue. I can tell only what helped me in such cases : 1. Get the vnet interfaces from your VM (virsh dumpxml s-xx-VM) 2. Get bridge infos using brctl show 3. Log into the system VM from the hypervisor as root using ssh -i .ssh/id_rsa.cloud [email protected] -p 3922 ( The IP is the link local IP) 4. Check each interface if you can ping gateways Bye, Bjoern On 04/03/2013 03:14 AM, Valery Fongang wrote: > Hi, > > I have the following setup: > > - 1 Physical Host with single NIC on Centos 6.3+KVM > - 1 Virtual Cloud Management Server on a separate Physical Host from > my KVM Host > - All 2 Physical servers plug into the same switch a NETGEAR GS748T > - My KVM host is connected on Port 1 where I have untagged VLAN trunk. > - My guest network VLAN range is set to 200-300. > - System VMs and Instances can be created with no issue.
