Oops! forgot to hit “reply all”. Sorry for the duplicates… Also adding additional observations/questions.
When I attach to the compute node, I don’t see any network namespaces. Is this normal? Admittedly, I haven’t read up on all the gory details of neutron (which I probably need to do this evening). Original message follows: ------------------------- Hi Yuanle, OK, checking the console log, it doesn’t appear that my instance is getting the dhcp assigned address… -------- Starting network... udhcpc (v1.20.1) started Sending discover...

Checking the DHCP logs on the network/controller node I see the address is being allocated. The instance, however, isn’t seeing the DHCP server. Multi-cast issue? Any guidance is appreciated and thanks again. Regards, /ross On Feb 10, 2014, at 7:58 PM, sylecn <syl...@gmail.com> wrote: > Hi Ross, > > 1.
