摘要:
A data center can share processing resources using virtual networks. A hosting program 9,10 hosts one or more virtual machines 11, 12. The program has a virtual interface VIF 1 14, to the virtual machines, a network interface 19 to enable communication between the virtual machines and other nodes of a network, and an infrastructure management interface 8, invisible to the virtual machines. The program has an intercept function 7 implemented as a comparator, switch or router, arranged to intercept a status message from one of the virtual machines, or applications run by that virtual machine. The status indication is sent to a status buffer 5 and is made available to the infrastructure management interface without providing a network path between the management interface and the virtual machine. This can discriminate between VM failure and communication failure, and the invisibility maintains isolation and helps avoid vulnerability to denial of service attack.
摘要:
A method and device to assist in the determination of protein domain boundaries is described. In particular the device is designed to provide a high throughput of proteolytic digestion of proteins to identify domains and their boundaries, for use in protein structure determination, in a manner that is amenable to automation. Proteases are immobilized in a convenient format such as a microtitre plate and preferably arranged in a matrix thereby allowing for simultaneous degradation of a protein by a number of proteases at a number of concentrations.

Example embodiments disclosed herein relate to a persistent volume at an offset of a virtual block device of a storage server. Example embodiments include requesting that a persistent volume be dissociated from a virtual block device in response to the termination of a virtual machine.
摘要:
In one implementation, a host platform implemented on a computing device hosting one or more virtual machines determines that a communication generated by a virtual machine and intended for another virtual machine is to be transmitted to a network appliance. Consequently, the host platform modifies the communication generated by the virtual machine.

摘要:
A data center can share processing resources using virtual networks. A virtual machine manager (10) hosts one or more virtual machines (11, 411), the virtual machines forming part of a segmented virtual network (34). Outgoing messages from the virtual machines have an intermediate destination address of an intermediate node in a local segment of the segmented virtual network, and the virtual machine manager has a router (18) for determining a new intermediate destination address outside the local segment, for routing the given outgoing message. By having the router as part of the virtual machine manager rather than having only a switch in the virtual machine manager, the need for virtual machines for implementing gateways is avoided. This can reduce the number of “hops” for the message between virtual entities hosted, and thus improve performance. This can help a service provider to share physical processing resources of a data center between different clients having their own virtual networks.
