Abstract
A server device includes a virtualization control unit, a storing unit, and a transferring unit. The virtualization control unit operates a virtual machine that is a virtualized computer to control a migration of the virtual machine with another server device. The storing unit stores therein a log, in an associated manner with the virtual machine, that is created by the virtual machine. When the virtual machine is migrated to the other server device, the transferring unit transfers, to the other server device, the log of the virtual machine targeted for a migration stored in the storing unit.
Claims5
A server device comprising:
- a virtualization control unit that controls, by operating a virtual machine that is a virtualized computer, a migration of the virtual machine with another server device;
- a storing unit that stores therein a log created by the virtual machine by associating the log with the virtual machine;
- and
- a transferring unit that transfers, to the other server device when the virtual machine is migrated to the other server device, a log of a virtual machine that is targeted for a migration stored in the storing unit.
A server device comprising:
- a storing unit;
- a virtualization control unit that controls, by operating a virtual machine that is a virtualized computer, a migration of the virtual machine with another server device;
- and
- a retaining unit that retains, in the storing unit, a log received from the other server device in accordance with the migration of the virtual machine.
A log transferring system comprising:
- a monitoring server device that includes
- a monitoring unit that monitors, when a log of a virtual machine has not been moved from a first server device to a second server device in accordance with a migration of the virtual machine, the state of the first server device, and
- a sending unit that sends, when the result of the monitoring of the monitoring unit indicates that the first server device is in an active state, a move instruction to move the log to the first server device;
- a first server device that includes
- a first storing unit that stores therein a log created by the virtual machine that has been migrated to the second server device, and
- a transferring unit that transfers, to the second server device when the move instruction is received, the log, which is stored in the first storing unit, of the virtual machine that has been migrated to the second server device;
- and
- a second server device that includes
- a second storing unit that stores therein a log created by the virtual machine that has been migrated from the first server, and
- a retaining unit that retains, in the second storing unit, the log transferred by the transferring unit.
