  • Patent number: 10509663
    Abstract: A customer submits a request to a virtual computer system service to launch a virtual machine instance and to join this instance to a managed directory. The service may obtain, from the customer, a domain name and Internet Protocol addresses for the selected directory, which is then stored within a systems management server. When launched, the instance may initiate an agent, which may communicate with the systems management server to obtain the configuration information. The agent may use this configuration information to establish a communications channel with the managed directory and create a temporary set of computer credentials that may be used to verify that the customer is authorized to join the virtual machine instance to the managed directory. If the credentials are valid, the managed directory may generate a computer account within the managed directory, which may be used to join the virtual machine instance to the managed directory.

  • Patent number: 10467033
    Abstract: Embodiments of the invention enable dynamic level boosting of operations across virtualization layers to enable efficient nested virtualization. Embodiments of the invention execute a first virtual machine monitor (VMM) to virtualize system hardware. A nested virtualization environment is created by executing a plurality of upper level VMMs via virtual machines (VMs). These upper level VMMs are used to execute an upper level virtualization layer including an operating system (OS). During operation of the above described nested virtualization environment, a privileged instruction issued from an OS is trapped and emulated via the respective upper level VMM (i.e., the VMM that creates the VM for that OS). Embodiments of the invention enable the emulation of the privileged instruction via a lower level VMM. In some embodiments, the emulated instruction is executed via the first VMM with little to no involvement of any intermediate virtualization layers residing between the first and upper level VMMs.

  • Patent number: 10437770
    Abstract: A hypervisor preferably provides VM (virtual machine) identification, priority and LUN/LBA range information to the HBA (host bus adapter) when a VM is created. Alternatively, the HBA can determine that a LUN/LBA range is new and request VM identity, priority and LUN/LBA range from the hypervisor. The HBA creates a table containing the VM identification, priority and LUN/LBA range. The HBA then detects operations directed to the LUN/LBA range and does a lookup to determine VM identification and priority. VM identification and priority are then mapped into a field in a frame using a unique identifier. The unique identifier can be placed using reserved bits on the existing Fiber Channel (FC) header or can use bits in an additional header, such as a modified IFR header or an optional device header. The VM identification aware HBAs register with the NS.

  • Patent number: 10430226
    Abstract: A technique is described for managing processor (CPU) resources in a host having virtual machines (VMs) executed thereon. A target size of a VM is determined based on its demand and CPU entitlement. If the VM's current size exceeds the target size, the technique dynamically changes the size of a VM in the host by increasing or decreasing the number of virtual CPUs available to the VM. To “deactivate” virtual CPUs, a high-priority balloon thread is launched and pinned to one of the virtual CPUs targeted for deactivation, and the underlying hypervisor deschedules execution of the virtual CPU accordingly. To “activate” virtual CPUs, the number of virtual CPUs, the launched balloon thread may be killed.

  • Patent number: 10394616
    Abstract: A computer receives an application and system configuration detailing program applications, operating systems, and when and/or on which system an application may hibernate and/or operate. The computer determines a baseline power consumption of each of the applications on each of the applicable systems and operates the applications on the most energy efficient system. The computer monitors and displays the energy consumption of each application and determines whether the applications capable of hibernation have been idle for a period of time. If so, the computer hibernates the application until the application is awoken. If the application is incapable of hibernation nor idle, the computer compares the consumption to the determined baseline consumption of an alternative system and, if the consumption is greater than the baseline consumption of an alternative system and the application is capable of operation on the alternative system, moves operation of the application to the more efficient system.
