Re: [openstack-dev] [nova] Feature suggestion - API for creating VM without powering it up
Thank you for your reply. This approach has 3 disadvantages that I can think of: 1. An image might have configurations processes that only happen on the first boot and require user input. This is a probable use-case 2. Not all images support cloud-init 3. This creates an unnecessary load on the compute node. I believe a create-in-shutoff-state is a more scalable, more robust approach.

Re: [openstack-dev] [nova] Feature suggestion - API for creating VM without powering it up
Looks like we can use user_data and cloud-init to do this stuff. Adding the following content into user_data.txt and launch instance like this: nova boot --user-data user_data.txt ..., the instance will shutdown after boot is finished. power_state: mode: poweroff message: Bye Bye You can find more details in cloud-init document[1].

The nova instance user spec has a use case. https://review.openstack.org/#/c/93/ Thanks, Kevin From: Matt Riedemann [mrie...@linux.vnet.ibm.com] Sent: Thursday, January 21, 2016 7:32 AM To: openstack-dev@lists.openstack.org Subject: Re: [openstack-dev] [nova] Feature suggestion - API for creating VM without powering it up On 1/20/2016 10:57 AM, Shoham Peller wrote: > Hi, > > I would like to suggest a feature in nova to allow creating a VM, > without powering it up. > > If the user will be able to create a stopped VM, it will allow for > better flexibility and user automation. > > I can personally say such a feature would greatly improve comfortability > of my work with nova - currently we shutdown each vm manually as we're > creating it. > What do you think? > > Regards, > Shoham Peller > > > __ > OpenStack Development Mailing List (not for usage questions) > Unsubscribe: openstack-dev-requ...@lists.openstack.org?subject:unsubscribe > http://lists.openstack.org/cgi-bin/mailman/listinfo/openstack-dev > What is your use case? -- Thanks, Matt Riedemann __ OpenStack Development Mailing List (not for usage questions) Unsubscribe: openstack-dev-requ...@lists.openstack.org?subject:unsubscribe http://lists.openstack.org/cgi-bin/mailman/listinfo/openstack-dev __ OpenStack Development Mailing List (not for usage questions) Unsubscribe: openstack-dev-requ...@lists.openstack.org?subject:unsubscribe http://lists.openstack.org/cgi-bin/mailman/listinfo/openstack-dev

[openstack-dev] [nova] Feature suggestion - API for creating VM without powering it up
Hi, I would like to suggest a feature in nova to allow creating a VM, without powering it up. If the user will be able to create a stopped VM, it will allow for better flexibility and user automation. I can personally say such a feature would greatly improve comfortability of my work with nova - currently we shutdown each vm manually as we're creating it. What do you think?
