Abstract: An “old” hypervisor is upgraded to or otherwise replaced by a “new” hypervisor without migrating virtual machines to a standby computer. The old hypervisor partitions the computer that it controls between a source partition and a target partition. The hypervisor and its virtual machines initially run on the source partition, while a new hypervisor is installed on the target partition. The virtual machines are migrated to the new hypervisor without physically moving the in-memory virtual-machine data. Instead, the old hypervisor sends memory pointers, and the new hypervisor claims the respective memory locations storing the virtual-machine data. After all virtual machines are migrated, the old hypervisor bequeaths the hypervisor memory and a last processor that the old hypervisor requires to run. The new hypervisor claims the bequeathed processor and hypervisor memory after the old hypervisor terminates to complete the upgrade/exchange.

Abstract: Principles for enabling power management techniques for virtual machines. In a virtual machine environment, a physical computer system may maintain management facilities to direct and control one or more virtual machines executing thereon. In some techniques described herein, the management facilities may be adapted to place a virtual processor in an idle state in response to commands from a guest operating system. One or more signaling mechanisms may be supported such that the guest operating system will command the management facilities to place virtual processors in the idle state.

Abstract: Software, firmware, and systems repurpose existing virtual machines. After a virtual machine is created, the system stores data associated with the virtual machine to permit its later repurposing. Repurposing data includes data associated with the virtual machine when the virtual machine is in a generic state from which it may be configured for use by two or more users/applications. When the system receives a request to create a new virtual machine, rather than create a brand new virtual machine, the system repurposes an existing virtual machine. The system identifies a virtual machine to repurpose, deletes data associated with the identified virtual machine, and loads a saved copy of repurposing data. The system may then load user data or otherwise customize the database and virtual machine.

Abstract: Methods, systems, and computer program products for providing fair unidirectional multi-queue virtual machine migration are disclosed. A computer-implemented method may include maintaining a current scan identifier for each of a plurality of streams used to migrate a virtual machine from a first hypervisor to a second hypervisor, determining when a current scan identifier of a first stream and a current scan identifier of a second stream are associated with different memory states of the virtual machine, and adjusting processing of memory updates when the current scan identifiers are associated with different memory states of the virtual machine. The adjusting may be performed, for example, by pausing processing on each stream having a current scan identifier subsequent to the earliest current scan identifier determined for the streams, and processing memory updates on each stream having a current scan identifier matching the earliest current scan identifier.

Abstract: The use of a skip element when redoing transactions, so as to avoid tracking dependencies between transactions assigned to different threads for parallel processing. When the second thread comes to a second task in the course of redoing a second transaction, if a first task that is mooted by the second task is not already performed, the second thread inserts a skip element associated with the object to be operated upon by the particular task, instead of actually performing the particular task upon the object. When the first thread later comes to the first task in the course of redoing a first transaction, the first thread encounters the skip element associated with the object. Accordingly, instead of performing the dependee task, the first thread skips the dependee task and perhaps removes the skip element. The result is the same regardless of whether the first or second task is redone first.
