However, since the DNS (Domain Name System, Domain Name System) cannot update the mapping between the domain name and the IP address in real time as the IP address of the virtual machine changes, the access of the source virtual machine user will still be sent to the source virtual machine after the virtual machine is migrated online. virtual machine, which leads to access errors of the source virtual machine user and affects the normal operation of the virtual machine

The invention discloses a virtual machine online migration method and a data package transmission method and device and belongs to the field of virtual machines. The virtual machine online migration method comprises the steps that a migration command is received, wherein the migration command is used for indicating a destination virtual machine manager where a source virtual machine is migrated; virtual machine data of the source virtual machine are obtained and are sent to the destination virtual machine manager in the form of a data package, so that a virtual machine is established by the destination virtual machine manager according to the virtual machine data; after all the virtual machine data are sent, the address of a physical device corresponding to the virtual machine identification of the source virtual machine is replaced with the address of a physical device where the destination virtual machine manager is located. According to the virtual machine online migration method and the data package transmission method and device, the address of the physical device existing after migration is conducted can be obtained during access according to the virtual machine identification, a user can have access to the virtual machine obtained after migration accurately, and access mistakes caused when a DNS is not set in time are avoided.
Description
technical field [0001] The invention relates to the field of virtual machines, in particular to a virtual machine online migration method, data packet transmission method and equipment. Background technique [0002] With the rapid development of data services, virtualization technology is more and more widely used in data centers. Virtualization technology divides the physical device into multiple isolated logical partitions, and simulates a system with complete hardware in each logical partition through the virtual machine manager (Hypervisor). The system is a virtual machine, and a virtual machine manager can manage multiple virtual machines. The data center can use multiple virtual machines to run multiple different operating systems on the same physical device through the virtual machine manager. [0003] When operations such as upgrading or data transfer need to be performed on a virtual machine or a physical device, online migration of the virtual machine is required....
