[Haizea] Live and Cold migration of VMs

[Aline Bousquet]

Hello again!

I've tried VM migration in simulated mode, and I couldn't manage to have
it working. 

The scenario I'm trying to test is when I have two hosts with 400 CPU
each. we then make sure that a VM with 100 CPU is running on each host.
Then, I ask for a third VM that requires 400 CPU. I thought that this last
VM should provoke the migration of a small VM into the other host, so that
the VM requesting high resources can run. All leases are ARs.

The problem is that Haizea just refuses the last lease. Is it normal that
the lease is denied? If yes, how will I be able to see if migration is
working (maybe on another scenario)?

I made sure that migration was enabled in the configuration file. 
I'm attaching the trace file I used.

Thanks a lot and happy new year!
