Method for virtual machine to provide web service, virtual machine monitor and system

Abstract

The invention discloses a method of providing web service of virtual machines, a virtual machine monitor and a system. The method includes the steps that the virtual machine monitor receives hyper text transport protocol (HTTP) request packets, the HTTP request packets carry to-be-accessed virtual machine domain names, the to-be-accessed virtual machine domain names are resolved into to-be-accessed virtual machine private addresses according to mapping relation between preset virtual machine domain names and the private addresses, and the web service corresponding to the virtual machines is accessed according to the to-be-accessed virtual machine private addresses. According to the method, the virtual machine monitor and the system, under the circumstance that a plurality of the virtual machines share one public internet protocol (IP) address, by means of the mapping relation between the virtual machine domain names and the private addresses, the virtual machine domain names are respectively mapped to the different virtual machines, and therefore access to the different virtual machines can be achieved. The method, the virtual machine monitor and the system have the advantages of simple arrangement and high availability, and can effectively solve the problem brought by exhaustion of an existing IPV4 address.

Description

technical field [0001] The invention relates to the technical field of the Internet, in particular, to a method for providing web services by a virtual machine, a virtual machine monitor and a virtual machine system. Background technique [0002] With the development of virtualization technology, virtual machines have been widely used, and there is an application demand for virtual machines to replace physical hosts as Web servers. However, in practical applications, multiple virtual machines are often created on one blade server. If a public IP address is configured for each virtual machine, it will cause great waste in the case of a serious shortage of IPV4 addresses. Therefore, In order to make full use of effective IP address resources, it is considered to configure a private address in the virtual machine and share a single public IP address to provide web services for the virtual machine. Since the web servers on the virtual machine all use the 80 target port and the ...

However, in practical applications, multiple virtual machines are often created on one blade server. If a public IP address is configured for each virtual machine, it will cause great waste in the case of a serious shortage of IPV4 addresses. Therefore, In order to make full use of effective IP address resources, it is considered to configure a private address in the virtual machine and share a single public IP address to provide web services for the virtual machine. Since the web servers on the virtual machine all use the 80 target port and the same external public network IP, it is impossible to locate the problem on the specific virtual machine web service, so it is also impossible to directly use NAT (NetworkAddressTranslation, network address translation) technology to solve it this problem
