4.4. Live KVM Migration with virsh

Processing controls
The maximum number of concurrent client connections to allow
over all sockets combined.
The minimum limit sets the number of workers to start up
initially. If the number of active clients exceeds this,
then more threads are spawned, upto max_workers limit.
Typically you'd want max_workers to equal maximum number
of clients allowed
The number of priority workers. If all workers from above
pool will stuck, some calls marked as high priority
(notably domainDestroy) can be executed in this pool.
Total global limit on concurrent RPC calls. Should be
at least as large as max_workers. Beyond this, RPC requests
will be read into memory and queued. This directly impact
memory usage, currently each request requires 256 KB of
memory. So by default upto 5 MB of memory is used
XXX this isn't actually enforced yet, only the per-client
limit is used so far
Limit on concurrent requests from a single client
connection. To avoid one client monopolizing the server
this should be a small fraction of the global max_requests
and max_workers parameter
