Abstract
A maintenance mode mechanism (MMM) expedites host maintenance in a cloud computing environment by intelligently suspending essentially inactive virtual machines. The user is given the option to enter maintenance mode using the MMM. The MMM determines essentially inactive VMs that can be suspended to reduce the number of VMs that need to be migrated prior to entering a maintenance mode. Metrics of the VMs associated with the host are analyzed to determine which VMs can be suspended. Parameters can also be set by the user to instruct the MMM to verify the selection of a specific VM with the user.
Claims10
An apparatus comprising:
- at least one processor;
- a memory coupled to the at least one processor;
- a cloud computing system with a host computer having a plurality of active virtual machines;
- a maintenance mode mechanism (MMM) residing in the memory and executed by the at least one processor, wherein the MMM determines at least one virtual machine of the plurality of active virtual machines on the host computer is an essentially inactive virtual machine and then suspends the essentially inactive virtual machine prior to placing the host computer in maintenance mode.
