Virtual computer system and method for swapping input/output devices between virtual machines and computer readable storage medium |
摘要 |
A command for swapping I/O devices between virtual machines is provided. When the command is input, each of I/O devices designated to be swapped is detached from corresponding one of swap-source-side and swap-destination-side virtual machines, and then attached to the other virtual machine. Simultaneously, definition information for the I/O devices in a VM-configuration information file previously stored in a non-volatile storage device such as a magnetic disk is updated automatically so as to reflect the swap of the I/O devices. This configuration enables swap of I/O devices through a single operation and update of I/O definitions in the VM-configuration information.
