Abstract: In one embodiment, a system for migrating virtual machines in a virtualization environment includes a plurality of host machines implementing the virtualization environment and a migration controller. Each of the host machines includes a hypervisor, one or more user virtual machines (UVMs) and a virtual machine controller. The system further implements a virtual disk comprising a plurality of storage devices, the virtual disk being accessible by the virtual machine controllers, which conduct I/O transactions with the virtual disk. The migration controller determines a segment size and, for each host machine, determines a number of required segments for the UVMs running on the host machine. The controller computes a number of reserved segments based on a total number of host machines and a largest one of the numbers of required segments. The reserved segments are then assigned among the plurality of host machines.

Abstract: An illustrative embodiment disclosed herein is an apparatus including a processor having programmed instructions to determine that a first packet, received from a first VM on a first host, has a destination address associated with a second VM on the first host, send the first packet to a service-focused bridge, generate a rule to redirect the first packet to the second VM based on the destination address, and generate execute the rule in response to receiving the first packet from the service-focused bridge.

Abstract: The disclosure relates to a method of switching data sources during a rolling upgrade of a leader-based distributed service. In at least one implementation, the method includes establishing, at a computing device in a cluster of devices in a network, a watch for notification of completion of a rolling upgrade on all devices in the cluster; restarting the computing device on completion of the rolling upgrade; switching, at the computing device, from a first data source to a second data source once the rolling upgrade is complete on all devices in the cluster; if the computing device is a leader device in the cluster, migrating tasks from the first data source to the second data source after completion of the rolling upgrade; and if the computing device is a non-leader device in the cluster, determining if task migration to the second data source is done and, when done, sending a store object to the second data source.

Abstract: A system and method can include requesting, by a network agent in a virtual machine in a hypervisor-attached infrastructure, a first identifier of a first resource device. The method can include comparing the first identifier to a plurality of known identifiers. The method can include determining a first location of the first resource device in response to matching the first identifier to one of the plurality of known identifiers. The method can include requesting a second identifier of a second resource device. The method can include determining a second location of the second resource device in response to the second identifier being different from each of the plurality of known identifiers. The second location can be different than the first location.
