摘要： A system and method include assigning, by an identifier management system of a virtual computing system, a hypervisor agnostic identifier to a virtual machine. The system and method also include creating a mapping of the hypervisor agnostic identifier to a first hypervisor specific identifier of the virtual machine, including storing the mapping in a database, and updating the mapping in response to a second hypervisor specific identifier being associated with the virtual machine. The updated mapping maps the hypervisor agnostic identifier to the second hypervisor specific identifier. The system and method further include making available the hypervisor agnostic identifier for use by other elements of the virtual computing system instead of the first hypervisor specific identifier and the second hypervisor specific identifier. The first hypervisor specific identifier and the second hypervisor specific identifier are hypervisor specific, while the hypervisor agnostic identifier is not hypervisor specific.

摘要： A method of determining an optimal host machine to place a virtual machine in a virtualization environment is described. The virtualization environment includes a first rack of host machines and a second rack of host machines, where a first host machine of the first rack of host machines is designated as a leader node. The method includes receiving a request to launch a second virtual machine configured to communicate with a first virtual machine. The method includes identifying, from the first rack of host machines and the second rack of host machines, a cluster of host machines. The method includes computing, for each host machine of the cluster, an aggregate network bandwidth consumed by the host machine. The method includes selecting a host machine from the cluster based on the aggregate network bandwidth computed for the selected host machine. The method includes launching the second virtual machine on the selected host machine.

摘要： In some embodiments, a system for testing performance of a virtualization environment comprises host machines, wherein each of the host machines comprises a hypervisor, one or more user virtual machines (UVMs) and a virtual machine controller, and one or more virtual disks comprising a plurality of storage devices. The one or more virtual disks may be accessible by the virtual machine controllers, and the virtual machine controllers conduct I/O transactions with the one or more virtual disks. The system may receive a specification of a hardware configuration for a host machine and configure the virtualization environment to incorporate the host machine. The system may then select one or more qualification tasks for a test scenario, execute the qualification tasks in the test scenario, and monitor performance of the virtualization environment. The system may then calculate a score assessing how well the hardware configuration may perform in the virtualization environment.

摘要： Systems and methods for managing contiguous addressing via virtual paging registers in a page table used in a high-performance computing platform. One embodiment commences upon initializing a first paging register with a first virtual address of a first virtual address length to form a first virtual address space, then receiving a request from a process to allocate physical memory corresponding to a second virtual address request. A memory allocator allocates the requested physical memory from a physical memory location determined by the memory allocator. An operating system or other sufficiently privileged access identifies a second paging register that is contiguously adjacent to the first paging register. If the second paging register is already in use, then the method identifies an unused (third) paging register into which the contents of the second paging register can be relocated. The method stores the second virtual address into the now freed-up second paging register.

摘要： A method for providing load balancing to a client node external to a clustered environment for storage management, includes deploying a lightweight load balancing component at the client node, receiving I/O requests issued by virtual machines hosted at the client node by the lightweight load balancing component, performing a hashing algorithm on content of the I/O requests by the lightweight load balancing component to identify one or more controller virtual machines at the clustered environment for handling the I/O requests and dynamically distributing the I/O requests from the lightweight load balancing component to the one or more controller virtual machines at the clustered environment for storage management.

摘要： Systems, methods, and computer readable medium for virtualized computing environments. A method for providing a connection between a guest virtual machine and a service virtual machine uses driver code functions to establish a listening port on the service virtual machine without providing a listening port on the guest virtual machine. The guest virtual machine initiates a remote procedure call socket between itself and the service virtual machine over a secure, hardened port. The service virtual machine presents an authority certificate by encoding into the authority certificate identifying information received from the guest virtual machine. The service virtual machine makes available (e.g., as an ISO image) the authority certificate, which is used to establish new secure connections. Communications continue, where some communications are initiated by the service virtual machine over the hardened port, and some communications are initiated on-demand by the guest virtual machine over newly-established and authenticated secure RPC connections.
