Abstract

Optimizing read operations to a storage device in a virtualized computing environment. A read system call is received by a virtual machine's (VM) operating system from an application running on the VM for data on a storage device. The VM is hosted by a hypervisor providing access to the storage device in a virtualized computing environment. A virtual file system (VFS) supported by the operating system is caused to call on a first para-virtualized file system (PVFS FE) supported by the operating system to execute the read operation. In response to determining by the PVS FE that the data to be read exists in a data cache of the PVFS FE, executing by the PVS FE the read operation from the cache of the PVFS FE.
