listen type socket support for rdp graphics

2020-03-19 Thread Vasiliy Tolstov
Hi! How hard implement listen type socket support for rdp graphics? VNC and SPICE already have such options? And does this support for rdp available for qemu driver? (I need to access qemu vm via rdp) Thanks! -- Vasiliy Tolstov, e-mail: v.tols...@selfip.ru
