Abstract: Methods and apparatus for reconfiguring hosts in provider network environments in which hosts are evaluated to determine if steps of a full rebuild can be skipped. The hosts may implement slots of different types for virtual machines (VMs). Upon detecting that slots of a particular type are needed, a host that implements slots of another type may be selected for reconfiguration. The host may be evaluated to determine if one or more steps of a full rebuild can be skipped. The host may then be reconfigured to implement slots of the target type according to results of the evaluation. In at least some reconfigurations, at least one step of a full rebuild procedure is not performed for the respective host. Results of previous reconfigurations may be fed back into the evaluation process and used as one of the criteria for determining if steps can be skipped.
