description The invention provides a domain management method in a virtual system. The method comprises the step that when a server determines that any one of VMs needs injection interruption, an inter-core interruption signal is sent to a physical CPU bound with a virtual CPU established for the VM through a physical CPU in a VMM domain, so that the virtual CPU established for the VM carries out the corresponding injection interruption. Based on the same invention concept, the invention further discloses a domain management device in the virtual system, the frequent contextual switch between the VMM and the VM can be reduced, and the efficiency of system virtualization is improved.
