Abstract: Method for managing virtual resources 20 on virtual machines (VMs) 10 by controlling execution of resources 20 by VM resource management layer 14 (VM instance) of trusted part 16 of a computer system, management layer 14 being unique in the computer system. VM instance 14 can be an interface between trusted part and VMs. Dynamic adding and releasing of VM resources by VM instance is defined. VM instance is on hypervisor, firmware layer, hardware layer and can be a license management system realized as billing system for using virtual resources. Billing information is securely transmitted to resource providers. Virtual resources 20 are software instances executed on a logical partition of a VM 10 and can be associated to physical resources for exclusive use. They can also be logical partitions, data processing units, main memories, network interfaces, resources of VMs. Accounting data for virtual resources are managed by VM instance 10.

Abstract: Disclosed is a method of restarting a software system 10 on a computer platform 12 after an unintentional software system shutdown. The method comprises generating a core dump file 14 on the computer platform when the software system shuts down unintentionally. Then restarting the software system, using a library 16 to copy software system related data 18 from the core dump file to the software system and continuing execution of the software system. The method may include the step of continuing execution of the software at a request of a request queue. The method may include checking the consistency of the software related data in the request and monitoring the software system for unintentional shutdown at the same request.
