Abstract: A pick assembly is provided, comprising a bit assembly and a holder assembly; the bit assembly comprising a bit support body, a fastener mechanism and a deflectable member, cooperatively configured such the deflectable member can be deflected responsive to the progressive coupling of the bit support body to the fastener mechanism. The holder assembly comprises a holder body and is configured for accommodating and retaining the bit assembly by interference means. The holder assembly and bit assembly are cooperatively configured such that the retention of the bit assembly by the holder assembly by interference means can be progressively increased responsive to the progressive coupling of the bit support body with the fastener mechanism when the bit assembly is accommodated by the holder assembly, operative to prevent substantial movement of the bit support body relative to the holder body in use.

Abstract: A logical communication path is provided between a target virtual machine (VM) and a host or application communicating with the VM. The target VM runs on a hypervisor host that has a hypervisor and a proxy agent. The hypervisor manages execution of the VM. A mapping is maintained indicating which VMs execute on which hosts. When the host or application is to send a message or packet to the target VM, the mapping is consulted and the hypervisor host hosting the target VM is identified. The message or packet, which may identify the target VM, is transmitted to the hypervisor host. A proxy agent at the hypervisor host selects a communication channel between the hypervisor and the target VM. The hypervisor then passes the message or packet through the selected channel to the target VM.

Abstract: Techniques are described to allow substation of blocks into a virtual machine image of an executing virtual machine. A patch may be applied to a first virtual machine image. One or more blocks modified by the patch are identified and copied to a host having a virtual machine executing from a virtual machine image that is based on the first virtual machine image (prior to the patch). While the virtual machine is executing, the substitution blocks are applied (supersede) corresponding original blocks in the virtual machine image. A guest operating system in the virtual machine may either begin using an executable file in a substitution block. In addition, the guest operating system may be forced to flush from memory and cache executable code replaced by the substitution block.

Abstract: Described are techniques for capturing and analyzing snapshots of virtual machines. One or more computers may automatically obtain snapshots of virtual machines as they are executing to form a pool of virtual machine snapshots. The virtual machine snapshots are then read to obtain a set of features properties of the virtual machine snapshots, including information about a running guest operating system, software installed on the virtual machine, metadata about the virtual machine itself, and others. The features or properties are analyzed, in one embodiment using a machine learning algorithm, to automatically compute and store information about the virtual machines.

Abstract: Tools and techniques for migrating applications to compute clouds are described herein. A tool may be used to migrate any arbitrary application to a specific implementation of a compute cloud. The tool may use a library of migration rules, apply the rules to a selected application, and in the process generate migration output. The migration output may be advisory information, revised code, patches, or the like. There may be different sets of rules for different cloud compute platforms, allowing the application to be migrated to different clouds. The rules may describe a wide range of application features and corresponding corrective actions for migrating the application. Rules may specify semantic behavior of the application, code or calls, storage, database instances, interactions with databases, operating systems hosting the application, and others.

Abstract: Techniques for analyzing virtual machine images are described. In one embodiment, a subset of settings is extracted from one or more virtual machine images, the virtual machine images store therein values of the settings. The settings are used by software executing in virtual machines of the virtual machine images, respectively. A target one of the virtual machine images is selected and target values of the settings are obtained from the target virtual machine image. Sample values of the settings are obtained from a plurality of virtual machine images. The subset formed by identifying similarities and differences of the values between the virtual machine images.

Abstract: Techniques are described for tracking and maintaining the lineage of virtual machines (VMs). As applications are built or compiled, information about the makeup or elements of the applications is captured. As applications are installed on VMs, that information is also captured. As the VMs are deployed to hosts, decommissioned, migrated between hosts, etc., that information is also maintained. Therefore, it is possible to trace relations between live VMs (and/or hosts they execute on) and the elements of applications installed on the VMs. For example, if an element is a source code file, it may be possible to link that source code file with particular hosts or VMs. Or, it may be possible to determine whether a given host or VM has a dependency on an application element. Given a dataset of lineage information, a wide range of previously unavailable information can be obtained.
