vhost-device-console - Console emulation backend daemon ## Description -This program is a vhost-user backend that emulates a VirtIO Consolw device. + +This program is a vhost-user backend that emulates a VirtIO Console device. +The device's binary takes as parameters a socket path, a socket number which +is the number of connections, commonly used across all vhost-devices to +communicate with the vhost-user frontend devices, and the backend type +"nested" or "network". + +The "nested" backend allows input/output to the guest console through the +current terminal. + +The "network" backend creates a local TCP port (specified on vhost-device-console +arguments) and allows input/output to the guest console via that socket. + +This program is tested with QEMU's
