Hello Kelcey, I think i have identified the issue. It seems that Cloudstack is associating the VM's interface with a non-existent bridge cloudVirBr0 instead of the cloudbr0 which it creates. I figured it from the virsh dump xml :
<interface type='bridge'> <mac address='06:66:e4:00:00:20'/> <source bridge='*cloudVirBr0*'/> <target dev='vnet7'/> <model type='virtio'/> <alias name='net0'/> <address type='pci' domain='0x0000' bus='0x00' slot='0x03' function='0x0'/> </interface> I grep'ped to the cloudstack config as well as database, i cannot seem to find any configuration pointing to *cloudVirBr0*. It would be great if you can share your thoughts. -- Regards, Kalpak On Thu, Aug 16, 2012 at 12:23 AM, citrix-dev <citrix-...@clogeny.com> wrote: > Hello Kelcey, > Thanks for the quick response. > > I create the additional guest network and the another network interface > gets added to the VM, although the VM isnt accessible from either of the > interfaces.
