Subject: [PATCH] domain_conf: Format iothread IDs more often

When formatting IOThreads (in virDomainDefIOThreadsFormat()), we
|
|
may only output the number of IOThreads, or the full list of IOThreads too:
|
|
|
|
<iothreads>4</iothreads>
|
|
<iothreadids>
|
|
<iothread id='1' thread_pool_max='10'/>
|
|
<iothread id='2' thread_pool_min='2' thread_pool_max='10'/>
|
|
<iothread id='3'/>
|
|
<iothread id='4'/>
|
|
</iothreadids>
|
|
|
|
Now, the deciding factor here is whether those individual
|
|
IOThreads were so called 'autofill-ed' or user provided. Well, we
|
|
need to take another factor in: if an IOThread has pool size
|
|
limit set, then we ought to format the full list.
|
|
|
|
But how can we get into a situation when a thread is autofilled
|
|
(i.e. not provided by user in the XML) and yet it has pool size
|
|
limit set? virDomainSetIOThreadParams() is the answer.
|
|
|
|
Sure, we could also unset the autofill flag whenever a pool size
|
|
limit is being set. But this approach allows us to not format
|
|
anything if the limits are reset (we don't lose the autofill
|
|
information).
