Configuration management for virtual machine environment

A computer system for controlling a connection between a virtual machine and a physical device, the computer system comprising:

• a virtual machine managing server;
• an endpoint managing server;
• and
• a storage for storing a first connection permission condition for the virtual machine and a second connection permission condition for the physical device;
• wherein the virtual machine managing server is configured to determine whether the virtual machine satisfies the first connection permission condition and whether the physical device satisfies the second connection permission condition in response to receipt of a connection request for connecting the physical device to the virtual machine, wherein the second connection permission condition comprises a setting of a configuration of the physical device and a setting of a context of the physical device comprising a location of the physical device and a current time;
• wherein the endpoint managing server is configured to send an instruction for changing a configuration of the virtual machine in response to a determination that the virtual machine does not satisfy the first connection permission condition;
• wherein the endpoint managing server is configured to send an instruction for changing a configuration of the physical device in response to a determination that the physical device does not satisfy the second connection permission condition;
• and
• wherein the virtual machine managing server is configured to accept the connection request to connect the physical device to the virtual machine in response to a determination that the virtual machine satisfies the first connection permission condition and that the physical device satisfies the second connection permission condition.

A computer program product for controlling a connection between a virtual machine and a physical device, the computer program product comprising a computer readable storage medium having program instructions embodied therewith, the program instructions executable by a processor to cause the processor to:

• determine, by a virtual machine managing server, whether the virtual machine satisfies a first connection permission condition and whether the physical device satisfies a second connection permission condition in response to receiving a connection request for connecting the physical device to the virtual machine, wherein the second connection permission condition comprises a setting of a configuration of the physical device and a setting of a context of the physical device comprising a location of the physical device and a current time;
• change, based on instructions sent from an endpoint managing server, a configuration of the virtual machine to satisfy the first connection permission condition in response to a determination that the virtual machine does not satisfy the first connection permission condition;
• change, based on instructions sent from the endpoint managing server, a configuration of the physical device to satisfy the second connection permission condition in response to a determination that the physical device does not satisfy the second connection permission condition;
• and
• accept, by the virtual machine managing server, the received connection request to connect the physical device to the virtual machine in response to a determination that the virtual machine satisfies the first connection permission condition and that the physical device satisfies the second connection permission condition.
