Subject: [PATCH] domain_conf: Format <defaultiothread/> more often
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
The <defaultiothread/> element is formatted inside
virDomainDefaultIOThreadDefFormat() which is called only from
virDomainDefIOThreadsFormat() (so that IOThread related stuff is
formatted calling one function). However, when there are no
<iothreadids/> defined (or only autoallocated ones are present),
then the outer formatting function exits early never calling the
<defaultiothread/> formatter.
