[Openstack-operators] [nova] Would an api option to create an instance without powering on be useful?

2018-11-30 Thread Matthew Booth
fully very small change in drivers to support it. Technically I don't see it as an issue. However, is it a change we'd be willing to accept? Is there any good reason not to do this? Are there any less esoteric workflows which might use this feature? Matt -- Matthew Booth Red Hat OpenSta

[Openstack-operators] [nova][cinder] Disabling nova volume-update (aka swap volume; aka cinder live migration)

2018-08-20 Thread Matthew Booth
ependent before doing this, at which point the volume itself should be migratable? If we can establish that there's an acceptable alternative to calling volume-update directly for all use-cases we're aware of, I'm going to propose heading off this class of bug by disabling it for non-cinder

Re: [Openstack-operators] [openstack-dev] [nova] about rebuild instance booted from volume

server is rebuilt, and the volume is not deleted. The user will still lose their data, of course, but that's implied by the rebuild they explicitly requested. The volume id will remain the same. [1] I suspect this would require new functionality in cinder to re-initialize from image. Matt --

that nobody will be sad if I remove all traces of it in its current form. If anybody is using it, or knows of anybody using it, could you let me know? What workarounds are you using? Secondly, if it did work is anybody interested in this feature? Thanks, Matt -- Matthew Booth Red Hat Engine

[Openstack-operators] [nova] Is verification of images in the image cache necessary?

2016-05-24 Thread Matthew Booth
dy be sad if I deleted it? Matt [1] Incidentally, there also seems to be a bug in this implementation, in that it doesn't hold the lock on the image itself at any point during the hashing process, meaning that it cannot guarantee that the image has finished downloading yet. -- Matthe
