  • Multi-virtual machine time consistent snapshots
    Patent number: 10417096
    Abstract: A method of generating time-coordinated snapshots across virtual machines (VMs) managed by at least one hypervisor executing in at least one host computer is described. The method includes: controlling at least one hypervisor to activate write caches for caching write traffic, generated by the VMs, targeting virtual disks; receiving, from the at least one hypervisor, messages that indicate idle periods in the write traffic; determining a quiescent window in the write traffic across the VMs from the idle periods; controlling the at least one hypervisor to flush the write caches up to a start time of the quiescent window; and controlling the at least one hypervisor to generate snapshots of the VMs.
