Good point :) and simpler too. ________________________________ From: Ignasi Barrera [[email protected]] Sent: Friday, December 05, 2014 12:08 PM To: [email protected] Subject: RE: assign a port on vm create?
If the option is available in the NovaTemplateOptions you don't need to manually create the options object. It is just a matter of order. Just call the specific NovaTemplateOptions methods after the "as" call. Calling methods from the superclass (TemplateOptions) will return that superclass, where concrete methods are not available.

The Network's builder will allow you to set portUuid (provide the port id for the port you created above). The problem above is that TemplateOptions, unlike NovaTemplateOptions, do not provide access to the Network type that would allow you to set port ids, which is something specific to Nova.

Zack, First, thanks for trying to help .. and yes, it is the ‘provide a port uuid’ on boot I am having trouble with from JClouds. Your listed steps are exactly what I did prior to this,( including grazing thru javadocs). I see that this can be done from Openstack/neutron command line but the jclouds Nova api options (org.jclouds.openstack.nova.v2_0.compute.options.NovaTemplateOptions ) doesn’t seem to allow specifying the port uuid ..

Here is my suggestion. Create a neutron network. Create a subnet (you will be allocating fixed IPs from that subnet's CIDR range). Create 8 ports on that subnet. These ports should specify fixed ips. These fixed ips should provide the subnet id and a fixed ip that is within the subnet range. Then: For each VM that you boot, you can provide a port uuid (when you boot with the nova API) http://jclouds.apache.org/reference/javadoc/1.8.x/org/jclouds/openstack/nova/v2_0/domain/Network.Builder.html#portUuid(java.lang.String) (It seems this is the part that you might be having trouble with). Let me know if this works or if you are having issues getting it to work. -Zack ________________________________ From: Andrea Turli [[email protected]<mailto:[email protected]>] Sent: Sunday, November 30, 2014 12:08 PM To: [email protected]<mailto:[email protected]> Subject: RE: assign a port on vm create? Thx Dan for the details. I think it is a specific question for Neutron support and I can't help you immediately on it. Could you please file an issue on jira reporting pretty much the same description so that we as community don't forget it again? thanks, Andrea Il 30/nov/2014 00:57 "dan rusak" <[email protected]<mailto:[email protected]>> ha scritto: Oh .. of course .. thought that might be a generic question. I use JClouds 1.8.0 (I notice that neutron is broken in 1.8.1 or would have upgraded). I am using Openstack icehouse on a local endpoint collocated with my VM installations with Chef-solo installed on my centos 6.5 image. I need to instantiate and provision 8 VMs which need to perform nfs mounts against each other during their provisioning and issue commands over ssh between them when all are up and operational. I have looked into everything I can find scraps of in the ether to provide static ips so this can happen but they all seem to dead end for one reason or another, usually resulting in silence in fact when someone else has the same general question. Anyway wrapping an ip in a port using the neutron api looked promising but need to get the VMs to use the port to see if that would even work. thx -dan -----Original Message----- From: Andrea Turli [mailto:[email protected]<mailto:[email protected]>] Sent: Saturday, November 29, 2014 9:31 AM To: [email protected]<mailto:[email protected]> Subject: Re: assign a port on vm create? Hi Dan, could you please clarify which jclouds version are you using? which provider/api are you consuming? Is it a public openstack (I guess) endpoint or an on-premise installation? If the latter what services can you use? I think those are useful preliminary questions to get the context of your use case.
