[libvirt] [PATCH 1/3 v2] daemon: Create priority workers pool

Tue Aug 23 18:22:01 UTC 2011
This patch annotates APIs with low or high priority.
In low set MUST be all APIs which might eventually access monitor
(and thus block indefinitely). Other APIs may be marked as high
priority. However, some must be (e.g. domainDestroy).
For high priority calls (HPC), there is new thread pool created.
HPC tries to land in usual thread pool firstly. The condition here
is it contains at least one free worker. As soon as it doesn't,
HPCs are placed into the new pool. Therefore, only those APIs which
are guaranteed to end in reasonable small amount of time can be marked
as HPC.
The size of this HPC pool is static, because HPC are expected to end
quickly, therefore jobs assigned to this pool will be served quickly.
It can be configured in libvirtd.conf via prio_workers variable.
Default is set to 5.
To mark API with low or high priority, append priority:{low|high} to
it's comment in src/remote/remote_protocol.x. This is similar to
autogen|skipgen.
