Quality of service is provided to prioritized VMs and applications, based on the varied quality of different shared computing resources. Each VM or application has an associated priority. A quality rating is dynamically assigned to each shared computing resource. Requests for shared computing resources made by specific VMs or applications are received. For each specific received request, the current priority of the requesting VM or application is identified. In response to each received request, a specific shared computing resource is assigned to the specific requesting VM or application. This assignment is made based on the current priority of the requesting VM or application and the current quality rating of the shared computing resource, thereby providing quality of service to the requesting VM or application corresponding to its current priority.

System and method for providing preferential I/O treatment to devices that host a critical virtual machine

Providing optimized quality of service to prioritized virtual machines and applications based on quality of shared resources

A computer-implemented method for sending information to guest systems within virtual machines may include receiving, from a guest system within a virtual machine hosted on a host system, a request for virtual device information about a virtual device which may inaccurately represent to the guest system a state of a physical storage device connected to the host system, gathering physical device information via the host system about the physical storage device connected to the host system, determining a mapping of the virtual device within the guest system to the physical storage device connected to the host system, correlating the physical device information with the mapping to determine accurate information about the virtual device and sending the accurate information about the virtual device from the host system to the guest system within the virtual machine. Various other methods, systems, and computer-readable media are also disclosed.
