Abstract
The method relates to the technical field of cloud computing, in particular to a method for setting the host name of a virtual machine. The method includes the steps that first, a virtual machine mirror image comprising one virtual serial port is made first, and a serial port service is made to operate in a default mode; then, the virtual machine is established on a host with the mirror image; the host sends a preset serial port command for setting the host name to the serial port of the virtual machine through a serial port tool; the specified virtual serial port is monitored and the received serial port command is analyzed through the serial port service of the virtual machine; if the analyzed host name is valid, the host name is set according to the information obtained through analysis by the serial port service of the virtual machine; if the analyzed command is incorrect or the host name is invalid, failure information is sent back to the host. Meanwhile, the host acquires the host name of the virtual machine outside the hypervisor through serial port communication. The method solves the problems that time is long and the success rate is low when the host name of the virtual machine is set and can be used for setting the host name of the virtual machine.
