Abstract
Methods and apparatus for providing availability information of a virtual machine to a load balancer are disclosed. The availability information of the virtual machine may be normalized information from performance metrics of the virtual machine and performance metrics of the physical machine on which the virtual machine operates. The normalized availability of a virtual machine is provided by a feedback agent executing on the virtual machine. Alternatively, the normalized availability of a virtual machine is provided by a feedback agent executing on a hypervisor executing multiple virtual machines on a common set of physical computing hardware.
