There were many places where we were inadvertently blocking the reactor thread. The reworking puts all calls to XenAPI on background threads, so that they won't block the reactor thread. Long-lived operations (VM start, reboot, etc) are invoked asynchronously at the XenAPI level (Async.VM.start, etc). These return a XenAPI task. We relinquish the background thread at this point, so as not to hold threads in the pool for too long, and use reactor.callLater to poll the task. This combination of techniques means that we don't block the reactor thread at all, and at the same time we don't hold lots of threads waiting for long-running operations. There is a FIXME in here: get_info does not conform to these new rules. Changes are required in compute.service before we can make get_info non-blocking. --- nova/virt/xenapi.py | 178 +++++++++++++++++++++++++++++++++++++++++++--------- 1 file changed, 147 insertions(+), 31 deletions(-) (limited to 'nova') diff --git a/nova/virt/xenapi.py b/nova/virt/xenapi.py index 9fe15644f..6b41061c1 100644 --- a/nova/virt/xenapi.py +++ b/nova/virt/xenapi.py @@ -16,15 +16,33 @@ """ A connection to XenServer or Xen Cloud Platform. + +The concurrency model for this class is as follows: + +All XenAPI calls are on a thread (using t.i.t.deferToThread, or the decorator +deferredToThread).
