The "tlsFromConfig" > doesn't end up in the config XML right? Just the migratable. The "tlsFromConfig" is libvirt internal attribute and is stored only in status XML to ensure that when libvirtd is restarted this internal flag is not lost by the restart. That flag is used to decide whether we should put *tls* attribute to migratable XML or not. I'll add it to the commit message to make it clear. I'll wait with pushing for your reply.
