by John Ferlan 28 Mar '17

28 Mar '17

https://bugzilla.redhat.com/show_bug.cgi?id=1398087 Clean up the virsh man page description for --pool-create-as in order to better describe how the various arguments are used when creating (or defining) a logical pool. Also move the --print-xml to the end of the qualifiers since it's not properly positionally situated for both --pool-create-as and --pool-define-as. Finally modify the storage pool XML parsing algorithm to check for the mismatched "name" and "source-name" as well as a more general if not provided, then set the default source format.

[libvirt] [PATCH 0/4] Start refactoring migration cookies

This series is a first step in refactoring migration cookies.
