More Information
Summary:A device (100) for hardware virtualization support is provided, the device (100) comprising: a hypervisor component (101) configured to launch a virtual machine (VM) and configured to exit and/or to enter a host level; a host system component (102) configured to process a configuration flag (CF) that enables an interrupt delivery mechanism; wherein the host system component (102) is configured torecord, if the configuration flag is set, a virtual timer number as a global variable, providing information to the hypervisor component (101) when a virtual timer is expired; and wherein the hypervisor component (101) is configured to process the virtual timer number of the global variable in the host level. 本发明提供种用于硬件虚拟化支持的设备(100)，所述设备(100)包括：虚拟机监控器组件(101)，用于启动虚拟机(virtual machine，VM)并且用于退出和/或进入主机级；主机系统组件(102)，用于处理启用中断传送机制的配置标记(configuration flag，CF)；其中，所述主机系统组件(102)用于，如果设置了所述配置标记，将虚拟定时器数记录为全局变量，从而当虚拟定时器到期时将信息提供给所述虚拟机监控器组件(101)；以及所述虚拟机监控器组件(101)用于在所述主机级中处理所述全局变量的所述虚拟定时器数。
