   @GutoVeronezi what do you think of @wido's suggestion?
   
   At the 
[agent.properties](https://github.com/apache/cloudstack/blob/2a3849b6ca6728cd94d447662b19b3833bfa9d86/agent/conf/agent.properties#L98)
 there are already some parameters regarding VM migrations, such as 
`vm.migrate.speed`:
   
   ```
   # set the vm migrate speed, by default, it will try to guess the speed of 
the guest network
   # In MegaBytes per second
   #vm.migrate.speed=0
   
   # set target downtime at end of livemigration, the 'hiccup' for final copy. 
Higher numbers
   # make livemigration easier, lower numbers may cause migration to never 
complete. Less than 1
   # means hypervisor default (20ms).
   #vm.migrate.downtime=0
   
   # Busy VMs may never finish migrating, depending on environment. When its 
available, we will
   # want to add support for autoconvergence migration flag which should fix 
this. Set an upper
   # limit in milliseconds for how long live migration should wait, at which 
point VM is paused and
   # migration will finish quickly.  Less than 1 means disabled.
   #vm.migrate.pauseafter=0
   ```
   
   Maybe adding this parameter nearby those (e.g. after 
`vm.migrate.pauseafter`) would help users to find it among other VM migration 
parameters. One option would be to change from 
`dest.domain.migrate.retrieve.timeout` to `vm.migrate.domain.retrieve.timeout`.
