Subject Re: Cross Zone Templates
Date Mon, 26 Jan 2015 22:45:32 GMT

The problem is that this doesn't work with the "region-wide" storage
model for S3.  Right now it's impossible to copy templates when using
S3 storage for the reasons I mentioned in my last response.  It's also
apparently impossible (without database editing) to make a template
cross-zone when creating it from a snapshot or volume.  Only allowing
cross-zone templates when registering them from a URL is stupid.

Thank You,
