[Kimchi-devel] [PATCH] Github issue #306: Creating a guest OS whose name contain spaces causes it to fail.

23 Jan 2014

From: "Otavio R. Piske" <angusyoung@gmail.com>

Kimchi fails to start the guest OS if the user names it with spaces. As pointed in the issue #306, other VM management interfaces prevent the user from creating a guest OS if the name contain invalid characters.

This patch adds a validation logic that prevents the user from naming a Guest OS with anything other than alphanumeric chars, '-', '.' or '_'.
