Remote Display

Using native RDP

• disable VRDE
• in Windows: system settings Allow Remote Desktop, disable Network Level Authentication
• set a user password (to avoid "account restricted")
• in VirtualBox port forward host 3389 to guest 3389 (default host IP is already 0.0.0.0)

Using VRDE

• Needs Oracle VM VirtualBox Extension Pack (downloads)

sudo vboxmanage extpack install ./Oracle_VM_VirtualBox_Extension_Pack-7.0.8.vbox-extpack
vboxmanage modifyvm WinDev2212Eval --vrde=on --vrde-address=0.0.0.0  # --vrde-port=3389
vboxmanage start WinDev2212Eval --type headless
