Swapping non-virtualizing and self-virtualizing devices

A computer program product for managing cloud computing resources, comprising a computer readable storage medium having program instructions embodied therewith, the program instructions executable by at least one processor to cause the at least one processor to:

• receive, via an interface, first Quality of Service (QoS) metrics associated with a virtualization instance (VI), wherein the VI is associated with VI QoS objectives;
• determine, in response to receiving the first QoS metrics, based at least in part on a first comparison of the first QoS metrics with the VI QoS objectives, that the VI cannot meet the VI QoS objectives;
• determine, in response to determining that the VI is unable to meet the VI QoS objectives, that a first virtual device associated with the VI comprises a virtual form of a non-virtualizing computing device, and that a first substitute virtual device, comprising a virtual form of a self-virtualizing computing device, is available and can meet the VI QoS objectives;
• and
• configure the VI to use the first substitute virtual device in place of the first virtual device.

A system for managing cloud computing resources, the system comprising:

• a consumer device configured to access a cloud computing environment;
• a computer, included in the cloud computing environment, wherein the computer comprises a virtualization instance (VI), a first computing device comprising a non-virtualizing type device, and a second computing device comprising a self-virtualizing type device, wherein the VI is configured to use a first virtual device to provide cloud computing services to the consumer device, and wherein the first virtual device comprises a virtual form of the first computing device;
• and
• a Quality of Service (QoS) manager communicatively coupled to the computer, wherein the QoS manager comprises at least one processor configured to:
• receive, via an interface, first Quality of Service (QoS) metrics associated with a virtualization instance (VI), wherein the VI is associated with VI QoS objectives;
• determine, in response to receiving the first QoS metrics, based at least in part on a first comparison of the first QoS metrics with the VI QoS objectives, that the VI cannot meet the VI QoS objectives;
• determine, in response to determining that the VI is unable to meet the VI QoS objectives, that a first virtual device associated with the VI comprises a virtual form of a non-virtualizing computing device, and that a first substitute virtual device, comprising a virtual form of a self-virtualizing computing device, is available and can meet the VI QoS objectives;
• and
• configure the VI to use the first substitute virtual device in place of the first virtual device.
