    Abstract: The present subject matter discloses methods and systems of sharing of peripheral devices in multi host computing systems (100). In one implementation, the method of sharing a peripheral device (116) amongst a plurality of hosts of the multi-host computing system (100) comprises receiving a request to switch the peripheral device (116) from a first operating system running on a first host from amongst the plurality of hosts to a second operating system running on a second host from amongst the plurality of hosts; generating a request for the first operating system to relinquish control of the peripheral device (116); determining the status of the relinquishment based on response generated by the first operating system; initiating a request for the second operating system to install a device driver for the peripheral device (116) upon determining successful relinquishment; and transferring ownership of the peripheral device (116) to the second operating system.

    Abstract: Described herein is a detachable multi-host computing system (100) having multiple host processors running different operating systems. In one implementation, the multi-host computing system (100) includes a detachable unit (102) and a base unit (104). Each of the detachable unit (102) and the base unit (104) includes an MR-IOV switch and a MR-PCIM for controlling the MR-IOV switch. In one embodiment, the MR-PCIM for both the detachable unit (102) and the base unit (104) is configured such that a single MR-PCIM switch may be used for enumerating peripheral devices connected to the detachable unit (102) and the base unit (104) when the detachable unit (102) and the base unit (104) are in an attached mode.

    Abstract: The present subject matter discloses methods and systems of application sharing in multi-host computing system (100) running multiple operating systems. In one embodiment, the method for application sharing in a multi-host computing system (100) comprises receiving a request to launch an application in a first operating system of the multi-host computing system (100) from a second operating system of the multi-host computing system (100), generating an application launch request to launch the application and transmitting the application launch request to a widget daemon running on the first operating system using a PCIe to PCIe application redirection engine. The method further comprises initiating an application sharing session between the first operating system of the multi-host computing system (100) from the second operating system of the multi-host computing system (100).
