摘要:
Virtual USB host controllers are arranged in a plurality of virtual machines constructed inside a physical machine; emulation of the unmounting and mounting of a USB device in a used physical USB port and modifications in the allocation of the USB port utilization rights of a virtual machine are carried out by means of an operation from a control terminal to make possible exclusive utilization; and the physical USB port is utilized jointly among the virtual machines.
摘要:
The network connection of a VM (target VM) that has been live-migrated from a first physical computer to a second physical computer is restored in a virtual computer system in which communication is performed using a certain type of information outside the jurisdiction of a virtualization mechanism. When receiving a packet from the VM, the first virtualization mechanism of the first physical computer extracts a certain type of information from the packet and registers the extracted certain type of information in a first management information unit. The first virtualization mechanism transmits the certain type of information in the first management information unit to the second virtualization mechanism of the second physical computer during live migration. The second virtualization mechanism registers the certain type of information in a second management information unit and transmits a certain type of packet including the certain type of information from at least one of one or more physical I/O devices of the second physical computer in order to restore the network connection of the target VM.

When a failure occurs in an LPAR on a physical computer under an SAN environment, a destination LPAR is set in another physical computer to enable migrating of the LPAR and setting change of a security function on the RAID apparatus side is not necessary. When a failure occurs in an LPAR generated on a physical computer under an SAN environment, configuration information including a unique ID (WWN) of the LPAR where the failure occurs is read, a destination LPAR is generated on another physical computer, and the read configuration information of the LPAR is set to the destination LPAR, thereby enabling migrating of the LPAR when the failure occurs, under the control of a management server.
