[pve-devel] [PATCH] balloon: don't set balloon && polling interval at start when livemigrate

[Alexandre Derumier]

We don't need to set balloon value and polling interval when a vm is coming from a livemigrate.
(Values are keep in guest memory)

So with autoballooning, this avoid to set the ballon size at ballon_min value when the vm is migrated
