[one-dev] VirtualMachineManagerDriver.rb

[Andrea Gardiman]

Hi,
I'm working on OpenNebula v. 4.4.1.
I have found that the function get_first_runable in the driver
VirtualMachineManagerDriver.rb has a limitation in the number of concurrent
thread per node, when the action has the attribute ":host".
In fact the function returns the index of an action only if there isn't
another thread that is working on the same host.
Why there is such a limitation?

The only wrong situation that come to my mind is when there are two threads
that are executing actions that regard the same VM. But in that case should
be a limitation per VM ID, not per node.

Am I missing something?

Thank you very much,
 Andrea Gardiman
