Single-click ejection of mountable devices in virtual machines
The granted patent US12056538B1 outlines a method for managing the unmounting of virtual peripheral devices associated with virtual machines (VMs) through a virtual machine manager (VMM). The process begins with the VMM receiving a device unmounting request via a graphical user interface. Following this, the VMM disassociates the corresponding physical device from the VM and instructs the host operating system (OS) to unmount the physical device. The method includes checks to determine if the virtual peripheral device is in use by another VM, ensuring that unmounting does not disrupt ongoing operations. If the device is not in use, a notification is sent to the host OS to proceed with the unmounting; otherwise, the request is withheld.
Additionally, the patent details the handling of error codes received from the VM during the unmounting operation. If the operation is successful, the VMM proceeds with disassociating and notifying the host OS. Conversely, if the operation fails, a notification is rendered in the graphical user interface to inform the user of the abnormal termination of the request. The patent also specifies that the peripheral devices can include various types of storage media, such as flash memory cards, compact disks, hard disk drives (HDDs), or solid-state drives (SSDs). Overall, the patent provides a structured approach to managing virtual peripheral device unmounting, enhancing the efficiency and reliability of virtual machine operations.
