摘要： A method for sharing memories of virtual machines is provided. The method is applied for a computer system configured to execute at least one virtual machine. The method includes the following steps. A memory map corresponding to the virtual machines is obtained, wherein usage states of memory pages of the virtual machine are stored in the corresponding memory map. Unused memory pages of the virtual machines are marked as free pages according to the corresponding memory map. The free pages of the virtual machines are shared. Therefore, the unused memory pages in the virtual machine can be shared. A computer system using the foregoing method is also provided.

摘要： In one embodiment, an apparatus for managing hypercalls in a hypervisor having an interrupt handler and a schedule is described. A deferrable low-overhead hypercall (DLH) module is configured to assign a separate DLH queue to each of a plurality of virtual machines when the virtual machine is initialized. Each entry in the separate DLH queue represents a hypercall routine. When one of the virtual machines notifies the interrupt handler of at least a deferrable hypercalls to be executed, the scheduler selects at least a virtual CPU (VCPU) and assigns them to the virtual machine to run on at least a physical CPU (PCPU). The DLH module executes the at least a deferrable hypercall inserted in a DLH queue assigned to the virtual machine before restoring the VCPU context to the virtual machine having the at least an assigned VCPU.
摘要翻译：在一个实施例中，描述了一种用于管理具有中断处理程序和调度的管理程序中的超线程的装置。当可虚拟机被初始化时，可延迟的低开销高调（DLH）模块被配置为向多个虚拟机中的每个虚拟机分配单独的DLH队列。单独DLH队列中的每个条目表示一个超级呼叫程序。当其中一个虚拟机向中断处理程序通知至少要执行的可延迟的超级呼叫时，调度器至少选择一个虚拟CPU（VCPU），并将其分配给虚拟机以运行至少一个物理CPU（PCPU）。在将VCPU上下文恢复到具有至少一个分配的VCPU的虚拟机之前，DLH模块至少执行插入到分配给虚拟机的DLH队列中的可延迟的超级呼叫。

摘要： A method of cloning data in a memory for a source virtual machine (VM) and at least one cloned virtual machine is proposed. A mapping relationship between a guest physical address from the source VM or the cloned VM and a host physical address of the memory is defined by a plurality of page tables configured in a plurality of hierarchical levels. In the method, metadata of the page tables in the highest level or the higher levels of the plurality of hierarchical levels is copied to the virtual machine. Remaining metadata of the page tables in the levels other than the highest level or the higher levels of the plurality of hierarchical levels is replicated to the virtual machine in response to the access operation. Data stored in the corresponding address of the memory is accessed according to the metadata and the replicated metadata.
