Re: [openstack-dev] [nova][neutron]About creating vms without ip address
Sounds interesting, however need to list all the possible usecases where this could prove useful.

Re: [openstack-dev] [nova][neutron]About creating vms without ip address
I think should we provide a feature about create vm without NIC, I plan to register a blueprint about this. If we could create a vm without NIC, we could attach a new NIC without IP address as eth0. 在 2014年1月26日，0:51，Dong Liu 写道： > Hi Miguel, > > Sorry for reply you so late. > > In current process, vm must be created with a security group(at least is > ‘default’).

Re: [openstack-dev] [nova][neutron]About creating vms without ip address
Hi Miguel, Sorry for reply you so late. In current process, vm must be created with a security group(at least is ‘default’). So there is a verify method about this. 在 2014年1月22日，16:19，Miguel Angel Ajo Pelayo 写道： > > > Hi Dong, > >Can you elaborate an example of what you get, and what you were expecting > exactly?. > >I have a similar problem within one operator, where they assign you sparse > blocks > of IP addresses (floating IPs), directly routed to your machine, and they also > assign the virtual mac addresses from their API. > >Direct routing means, that the subnet router will route your IP from > outside the > subnet directly through your subnet, to your machine..., and the traffic > (with external IP) > is routed back to this internal router through the subnet to this router. > > Chears, > > - Original Message - >> From: "Dong Liu" >> To: "OpenStack Development Mailing List (not for usage questions)" >> >> Sent: Tuesday, January 21, 2014 9:52:44 AM >> Subject: [openstack-dev] [nova][neutron]About creating vms without ip address >> >> Hi fellow OpenStackers >> >> I found that we could not create vms without ip address.

We shouldn't shut off network's DHCP entirely though since we still need Fuel VM to receive some address for external connectivity. -- Kind regards, Yuriy. ___ OpenStack-dev mailing list OpenStack-dev@lists.openstack.org http://lists.openstack.org/cgi-bin/mailman/listinfo/openstack-dev

Hello. On Tue, Jan 21, 2014 at 12:52 PM, Dong Liu wrote: > What's your opinion? > We've just discussed a use case for this today. I want to create a sandbox for Fuel but I can't do it with OpenStack. The reason is a bit different from telecom case: Fuel needs to manage nodes directly via DHCP and PXE and you can't do that with Neutron since you can't make its dnsmasq service quiet. So, it's a great idea. We can have either VMs with no IP address associated or networks with no fixed IP range, either could work. There can be a problem with handling floating IPs though. -- Kind regards, Yuriy. ___ OpenStack-dev mailing list OpenStack-dev@lists.openstack.org http://lists.openstack.org/cgi-bin/mailman/listinfo/openstack-dev
Re: [openstack-dev] [nova][neutron]About creating vms without ip address
Hi Dong, Can you elaborate an example of what you get, and what you were expecting exactly?. I have a similar problem within one operator, where they assign you sparse blocks of IP addresses (floating IPs), directly routed to your machine, and they also assign the virtual mac addresses from their API. Direct routing means, that the subnet router will route your IP from outside the subnet directly through your subnet, to your machine..., and the traffic (with external IP) is routed back to this internal router through the subnet to this router.

[openstack-dev] [nova][neutron]About creating vms without ip address
Hi fellow OpenStackers I found that we could not create vms without ip address. But in the telecom scene, the ip address usually managed by the telecom network element themselves. So they need a vm without ip address and configurate it through some specific method. How can we provide a kind of vms like this. I think provide a bility that allow tenant to create vm without ip address is necessary. What's your opinion?
