Likitha Shetty commented on CLOUDSTACK-5485:
--------------------------------------------

With the above commit the number of threads on SSVM agent for connection with MS will be configurable
using global configuration _workers_. The default value for _workers_ is 5.
Increase the config value to allow for more than 5 SSVM tasks to be processed concurrently.
For the new global config value to take effect, along with restarting the MS, SSVM needs to
be stopped and started.

By making it configurable using the global config we ensure that even if SSVM is destroyed
the value wont be lost.

> Vmware - When 10 hourly snapshots are scheduled at the same time , we see only 5 of them
being processed actively at the same time.
> Set up :
> Advanced Zone with 2 5.1 ESXI hosts.
> Steps to reproduce the problem:
> 1. Deploy 5 Vms in each of the hosts , so we start with 10 Vms.
> 2. Start concurrent snapshots for ROOT volumes of all the Vms.
> Noticed that on the Vsphere client , only 5 of these snapshots gets executed in parallel.Rest
of them get picked up when the current  snapshot jobs complete.
> Why cant we do more than 5 parallel tasks ?
