Abstract
Techniques for providing high availability to virtual machines executing in a nested hypervisor. A high availability agent executing within a slave computer in a cluster detects when a master server becomes unavailable and restarts virtual machines from the master server in response. The high availability agent detects whether any of the virtual machines were executing a nested hypervisor within the master server and starts a high availability agent within such hypervisors. The high availability agent within the nested hypervisor is a modified high availability agent with respect to the high availability agent executing in physical servers. The modified high availability agent does not participate in master election and also cannot elect the virtual machine on which it runs as master.
