Each of the secondary client devices may be coupled to one or more peripherals. The primary client in the logical client may use a virtual machine (VM) and/or an application that uses one or more peripheral devices. The primary client device may not be coupled to the one or more peripheral devices used by the application and/or the VM. The primary client device may access the peripheral devices coupled to secondary client devices in order to use the application and/or the VM. ## Claims ### Claim 1 A method comprising: obtaining, by a virtual machine (VM) host, configuration data comprising a list of virtual peripheral devices for a VM used by a logical client comprising a first client device and a second client device;
