摘要:
This application discloses a virtual machine hot migration method performed by a virtual machine hot migration apparatus to a cloud computing system including a plurality of hosts, each host including a plurality of virtual machines. The apparatus obtains a load of each host, determines a host whose load exceeds a preset threshold as a source host, determines a to-be-hot-migrated target virtual machine in the source host; and controls the target virtual machine to be hot-migrated from the source host to a target host. According to the solutions provided in the embodiments of this application, when a load of a host is excessively high, a redundantly configured virtual machine on the host is hot-migrated to another host, thereby improving the resource utilization rate of the host when use by a user is ensured.
