Cloudlet still submit by the broker to a destructed VM.

[Steven Wong]

Dear Mr.Manoel,

I have a question regarding cloudsim plus.

Let say I have already request on destructing the VM earlier with some constraint given.

For example VM ID: 6 have been destructed at 20 sec during simulation runtime.

However when I have submit a list of workload during maybe 40-50 sec during simulation runtime.

The datacenter broker still submits to VM ID: 6 to process.

I have included the simulation code for you to check on too.

Thanks on your effort on maintaining cloudsim plus. Much appreciated.

Regard,

Steven Wong

Hello Steven,

Could you please update your fork and check if the issue persists?

I've fixed some issues related to VM submission and destruction.

Just let me know what happened.

Dear Mr.Manoel,

Upon update the package and testing with the code, I still found out the problem still persists.

Thanks for the hard work!

Hello Steven, I ran your example but couldn't spot the issue.

All your VMs are being destroyed only at the end of the simulation.

Could you try to slim down your example so that the issue is clear?

Make sure to just print what is relevant for the issue.

Realize your Cloudlet's BW and RAM utilization are requesting more resources than it is available.

If BW and RAM are not relevant to reproduce the issue, don't set UtilizationModel for such resources.

Dear Mr. Manoel,

Here's another simplified example, sorry about the messy output there.

So here, I intend to destroy VM ID: 0 in 23 seconds during simulation runtime.

 # 23.06: Intention destroying Vm 0/Broker 2

But as you can see at the 35 seconds during simulation runtime, i have submitted three cloudlet

INFO  36.06420161219916: DatacenterBrokerSimple2: Sending Cloudlet 6 to Vm 2 in Host 0/DC 1.
INFO  36.06420161219916: DatacenterBrokerSimple2: Sending Cloudlet 7 to Vm 0 in Host 0/DC 1.
INFO  36.06420161219916: DatacenterBrokerSimple2: Sending Cloudlet 8 to Vm 1 in Host 0/DC 1.

Although I have already destroyed VM ID: 0 at 23 during simulation runtime. Still, he broker assign the cloudlet to VM ID : 0.

Hope this example could highlight the issue.

Hello Steven,

Thanks for reporting.

I've just fixed the issue.

Dear Mr.Manoel,

All work as intended for my simulation here.

Thanks for your time to help me during your weekend. Much appreciated!

Good luck with everything!
