Abstract
A HA computer system is configured to support the operation of an active and a standby virtual machine, and the active virtual machine supports one or more first computer processes and the standby virtual machines supports duplicates of the one or more first computer processes. Each active virtual machine monitors and stores a state of the first computer processes and periodically pauses to only synchronize some of the state of the first computer processes running on the active VM with state associated with the duplicate processes running on the standby VM stored in a first region of virtual memory.
