Abstract:
1. A virtual server for supporting a zero client, comprising: a virtual machine management agent unit to generate a virtual host interface resource pool and a directly allocatable host interface resource pool by classifying attributes of host interface resources in a host interface resource pool; and a virtualization unit to provide a host interface of a virtual machine by selectively using one of an emulation mode in which a virtual host interface set corresponding to the virtual host interface resource pool is generated and a direct connection mode in which a directly allocatable host interface set corresponding to the directly allocatable host interface resource pool is connected to the zero client, wherein the virtual machine management agent unit is configured to generate the host interface resource pool by collecting host interface information of the virtual server, and generate the virtual host interface resource pool and the directly allocatable host interface resource pool, and wherein the classifying comprises analyzing the attributes of the host interface resources in the generated host interface resource pool, and storing the analyzed attributes in the virtual host interface resource pool and the directly allocatable host interface resource pool, respectively, and wherein the analyzing the attributes comprises calculating at least one of a number of virtual processors that can be operated by the virtual server, a size of memory allocated to each zero client, a number of disk images of the virtual machine installed on the virtual server, a number of disk partitions of the virtual machine installed on the virtual server, and a number of virtual network devices that can be generated in the virtual server.
