The method is always returning true, causing the VmAllocationPolicyMigration to ignore all available Hosts for VM migration.
The issue happend after introducing the equals() implementation using Lombok EqualsAndHashCode annotation and creating the HostAbstract class.

Since the annotation was inside the HostSimple class and it doesn't have any attributes annotatted with EqualsAndHashCode.Include, the equals() implementation was not including any fields.

That annotations need to be moved to the HostAbstract class.
