Abstract

A system and an article of manufacture for facilitating customer-initiated virtual machine (VM) migration and swapping include obtaining documentation of at least one performance parameter of two or more virtual machines running on two or more physical machines, obtaining a request for a virtual machine exchange from a user of a first virtual machine, wherein the request comprises a preference for at least one desired performance parameter in at least one additional virtual machine, matching the request from the user of the first virtual machine with at least one additional virtual machine that includes the at to least one desired performance parameter without assistance from a cloud provider, and exchanging the first virtual machine with a virtual machine from the at least one additional virtual machine that includes the at least one desired performance parameter.

(ii) a second request for a virtual machine exchange from a user of a second virtual machine, wherein the second request comprises a preference for at least one desired virtual machine performance parameter;

matching the first request with the second request upon determining that;

(i) the first virtual machine includes the at least one desired virtual machine performance parameter from the second request, and (ii) the second virtual machine includes the at least one desired virtual machine performance parameter from the first request; and

exchanging the first virtual machine with the second virtual machine based upon matching the first request with the second request and without assistance from a cloud provider, wherein said exchanging comprises;

re-booting each of the first virtual machine and the second virtual machine to a stateless mode;

reading one or more items of data from the first virtual machine;

writing the one or more items of data from the first virtual machine to a shared storage component;

reading one or more items of data from the second virtual machine;

writing the one or more items of data from the second virtual machine to a persistent storage component associated with the first virtual machine;

reading the one or more items of data from the first virtual machine from the shared storage component; and

writing the one or more items of data from the first virtual machine from the shared storage component to a persistent storage component associated with the second virtual machine;

wherein at least one of the plurality of method steps is carried out by a computer device.

2. The article of manufacture of claim 1, wherein the method steps comprise:

obtaining assent from the user of the first virtual machine and the user of the second virtual machine for said exchanging.

3. The article of manufacture of claim 1, wherein the at least one virtual machine performance parameter comprises central processing unit, memory, network, storage, and/or number of hops between virtual machines.

4. The article of manufacture of claim 1, wherein said exchanging comprises using a third party broker.

5. The article of manufacture of claim 4, wherein the method steps comprise:

obtaining assent, via the third party broker, from the user of the first virtual machine and the user of the second virtual machine for said exchanging.

6. The article of manufacture of claim 4, wherein the method steps comprise:

revoking, via the third party broker, user access to the first virtual machine and the second virtual machine; and

shutting down, via the third party broker, the first virtual machine and the second virtual machine.

7. The article of manufacture of claim 6, wherein the method steps comprise:

attaching, via the third party broker, a remote disk to each virtual machine;

setting, via the third party broker, the remote disks as boot; and

unmounting, via the third party broker, each of one or more virtual machine disks.

8. The article of manufacture of claim 7, wherein the method steps comprise:

restarting, via the third party broker, each virtual machine; and

swapping, via the third party broker, the virtual machine disks using an intermediary storage controlled by the third party broker.

9. The article of manufacture of claim 8, wherein the method steps comprise:

removing, via the third party broker, the remote disks; and

restoring, via the third party broker, one or more newly copied disks on the virtual machine disks and rebooting the virtual machines.

10. The article of manufacture of claim 1, wherein the method steps comprise:

verifying the documentation of the at least one virtual machine performance parameter of the two or more virtual machines, wherein said verifying comprises running at least one micro-benchmark of each virtual machine for comparison with the documentation.

11. The article of manufacture of claim 1 wherein the method steps comprise:

exchanging ownership of the first virtual machine and the second virtual machine in connection with exchanging the first virtual machine with the second virtual machine.

12. A system for exchanging two or more virtual machines, comprising:

at least one distinct software module, each distinct software module being embodied on a tangible computer-readable medium;

a memory; and

at least one processor coupled to the memory and operative to;

obtain documentation of at least one performance parameter of two or more virtual machines each running on a respective physical machine;

obtain;

(i) a first request for a virtual machine exchange from a user of a first virtual machine, wherein the first request comprises a preference for at least one desired virtual machine performance parameter; and

(ii) a second request for a virtual machine exchange from a user of a second virtual machine, wherein the second request comprises a preference for at least one desired virtual machine performance parameter;

match the first request with the second request upon determining that;

(i) the first virtual machine includes the at least one desired virtual machine performance parameter from the second request, and (ii) the second virtual machine includes the at least one desired virtual machine performance parameter from the first request; and

exchange the first virtual machine with the second virtual machine based upon matching of the first request with the second request and without assistance from a cloud provider, wherein said exchanging comprises;

re-booting each of the first virtual machine and the second virtual machine to a stateless mode;

reading one or more items of data from the first virtual machine;

writing the one or more items of data from the first virtual machine to a shared storage component;
