| [3] | If Firewalld is running, allow ports you set for VRDE port or plan to use for it. (it's [5001] port on this example) |
|
[root@dlp ~]# firewall-cmd --add-port=5000-5010/tcp success [root@dlp ~]# firewall-cmd --runtime-to-permanent success |
| [4] | On VRDP enabled VRDP Virtual Machine, it's possible to connect with RDP. The example below is on Windows 11. Run Remote Desktop Client and specify [(VirtualBox Server's Hostname or IP address):(vrdeport set for the VM)] to connect to VM. |
|
| [5] | After connected successfully, VM console is shown. |
|
| [6] | Installation finished and Virtual Machine is running normally. |
