Canonical naming for non-x86 architectures

[James Page]

Various non-x86 architectures (POWER and ARM) don't correctly canonicalize into things that libvirt natively understands.

The attached patches normalizes some alternative architecture strings into standardized ones for Nova/libvirt.

Status changed to 'Confirmed' because the bug affects multiple users.

The original source of this bug is incorrect configuration of the 'architecture' property in a glance image; if the standard Ubuntu/Debian architecture names are used, then they don't match the architecture that nova-compute/libvirt detect on the hypervisors, and instances can't be scheduled appropriately.

I've proposed a fix to simplestreams (a distribution tool for images) but it would be nice if openstack could be a little friendlier in mapping the distro architecture names into canonical forms as well.

This is simply user error - OpenStack has a documented list of required architecture values

http://docs.openstack.org/cli-reference/content/chapter_cli-glance-property.html

Nova should not have to apply workarounds for every possible way the user can specify incorrect architecture names.

[James Page (james-page)]

I don't think its unreasonable to map well know architecture names used by distributions into something OpenStack understands - this is not 'every possible way' - its if the user makes and (somewhat understandable) choice of using the Ubuntu/Debian architecture name for their image.

Daniel,
Your suggestion that openstack should not be in charge of "fixing" strings does make sense, but it should at least be configurable to reject invalid strings for well known properties. That way the user fails the upload (or the property set) rather than arbitrary failure further down the line.

This bug is believed to be fixed in simplestreams in version 0.1.0. If this is still a problem for you, please make a comment and set the state back to New

Thank you.
