When I'm connected on another Microsoft Windows 7/10 machine with Microsoft RDP client (mstsc.exe) to manage remotely this machine in the same case, everything is also working fine.To avoid firewall problems, ensure that the port your remote desktop software uses is open on any firewalls residing between client computers and the server they connect to. When I'm locally on the Windows 10 machine where Oracle VM VirtualBox installed, the keyboard is working fine inside the Debian 9 VM. It's easy to dismiss the notion that a firewall could contribute to a remote desktop not working, but it's quite common.

I will explain my setup to reproduce on your side:ġ- I'm using Remmina 1.3.3 in Debian 10 (32 bit) client machineĢ- I try to connect to a remote Windows 10 Pro (64 bit) machineģ- The keyboard and mouse (everything is working fine)Ĥ- On this remote Windows 10 machine, Oracle VM VirtualBox is installedĥ- Inside Oracle VM VirtualBox is running a Debian 9 (32 bit) virtual machine in a console mode only (no X11)Ħ- In this VM, when I'm using Remmina, I'm unable to type with the keyboard.
