摘要：Techniques are described for updating a host operating system on a serverwhile maintaining virtual machines running on the server. An updated host operatingsystem is copied to the server. The currently active host operating system freezes thevirtual machines but leaves them resident in RAM. The allocations and state for eachvirtual machine is copied to RAM or local storage. The active host operating system isshut down. Instead of issuing a command to reboot the server after it finishes shuttingdown, the active host operating system transfers execution to a loader. The loader readsthe kernel of the updated host operating system into RAM along with an allocation mapfor the virtual machines and instructions to resume the virtual machines. The loadertransfers execution to the updated host operating system entry point, and the updatedhost operating system loads the states of the virtual machines and resumes them.
