Abstract

A seamless application integration apparatus and method are provided. The seamless application integration apparatus includes a seamless integration server that is installed in a host virtual machine so as to provide a seamless application integration (SAI) environment in a virtualization system that comprises the host virtual machine and at least one guest virtual machine. The apparatus also includes a dynamic reconfiguration unit determines whether a seamless integration client that corresponds to the seamless integration server has been installed in the guest virtual machine, and that may install the seamless integration client in the guest virtual machine according to the determination result.

Claims

1. A seamless application integration apparatus comprising:

a seamless integration server configured to be installed in a host virtual machine to provide a seamless application integration (SAI) environment in a virtualization system that comprises the host virtual machine and at least one guest virtual machine; and

a dynamic reconfiguration unit configured to determine whether a seamless integration client that corresponds to the seamless integration server has been installed in the guest virtual machine, and to install the seamless integration client in the guest virtual machine based on the determination result.

2. The seamless application integration apparatus of claim 1, wherein the dynamic reconfiguration unit is further configured to examine a process list or a file system of the guest virtual machine to detect whether the seamless integration client has been installed.

3. The seamless application integration apparatus of claim 1, wherein the dynamic reconfiguration unit is further configured to

access a file system of the guest virtual machine to store an installation file of the seamless integration client,

access a memory area of the guest virtual machine to insert a bootstrap code to run the seamless integration client, and

change a location of a program counter of the guest virtual machine to a location at which the bootstrap code is inserted.

4. The seamless application integration apparatus of claim 1, wherein the dynamic reconfiguration unit is further configured to

determine whether the memory area of the guest virtual machine is modified as a result of execution of the installed seamless integration client,

if the memory area of the guest virtual machine is modified, perform a flush on a translation lookaside buffer for the modified memory area, and

if the memory area of the guest virtual machine is not modified, flush a CPU cache and restore VCPU context to return the program counter to an original location.

5. The seamless application integration apparatus of claim 1, wherein the dynamic reconfiguration unit is further configured to be located in a remote system which is physically separated from the virtualization system and to perform installation of the seamless integration client.

6. A seamless application integration apparatus comprising:

a seamless integration server configured to be installed in a host virtual machine to provide a seamless application integration (SAI) environment in a virtualization system that comprises the host virtual machine and at least one guest virtual machine;

a seamless integration client that corresponds to the seamless integration server and configured to be installed in the guest virtual machine; and

a dynamic reconfiguration unit configured to determine whether a version of the seamless integration server matches a version of the seamless integration client, and to replace the seamless integration client based on the determination result.

7. The seamless application integration apparatus of claim 6, wherein the dynamic reconfiguration unit comprises:

a dynamic reconfiguration server configured to transmit a version check message; and

a dynamic reconfiguration client configured to receive the version check message, determine whether the version of the seamless integration client matches the version of the seamless integration server based on the received version check message, replace the seamless integration client based on the determination result to match the versions between the seamless integration server and the seamless integration client, and generate a response to the version check message.

8. A seamless application integration apparatus comprising:

a seamless integration server configured to be installed in a host virtual machine to provide a seamless application integration (SAI) environment in a virtualization system that comprises the host virtual machine and at least one guest virtual machine;

a seamless integration client that corresponds to the seamless integration server and configured to be installed in the guest virtual machine;

a dynamic reconfiguration server configured to determine whether each component of the seamless integration server supports a runtime environment of the guest virtual machine and replace or add a component in the seamless integration server based on the determination result; and

a dynamic reconfiguration client configured to determine whether each component of the seamless integration client supports a runtime environment of the host virtual machine and replace or add a component in the seamless integration client based on the determination result.

9. A seamless application integration method comprising:

determining whether a seamless integration client is installed in a guest virtual machine, wherein the seamless integration client corresponds to a seamless integration server which is installed in a host virtual machine that provides a seamless application integration (SAI) environment in a virtualization system that comprises the host virtual machine and at least one guest virtual machine; and

installing the seamless integration client in the guest virtual machine based on the determination result.

10. The seamless application integration method of claim 9, further comprising:

determining whether a version of the seamless integration server matches a version of the seamless integration client; and

replacing the seamless integration client based on the determination result.

11. The seamless application integration method of claim 10, further comprising:

determining whether the seamless integration server supports a runtime environment of the guest virtual machine or whether the seamless integration client supports a runtime environment of the host virtual machine; and

replacing or adding the seamless integration server or the seamless integration client based on the determination result.

12. A seamless application integration (SAI) method of a control virtual machine (VM) that includes an SAI server that is executed on a device, the SAI method comprising:

in response to a guest VM being ready to execute on the device, determining whether the a SAI client corresponding to the SAI server is installed in the guest VM;

in response to determining that the SAI client corresponding to the SAI server is not installed in the guest VM, installing the SAI client in the guest VM; and

executing the guest VM.

13. The SAI method of claim 12, wherein, in response to the SAI client corresponding to the SAI server being installed in the guest VM, the method further comprises determining whether the version of the SAI client corresponds to the current version of the SAI server.

14. The SAI method of claim 13, wherein, in response to the current version of the SAI client not being installed in the guest VM, the method further comprises updating the SAI client with the current SAI client corresponding to the current SAI server.

15. The SAI method of claim 12, wherein, in response to the SAI client corresponding to the SAI server being installed in the guest VM, the method further comprises determining whether the SAI server of the control VM and the SAI client of the guest VM match such that each supports a runtime environment of the other.

16. The SAI method of claim 15, wherein, in response to the SAI client not supporting the runtime environment of the current SAI server, the method further comprises replacing the SAI client of the guest VM with a SAI client that supports the runtime environment of the current SAI server.
