Install VirtualBox on CentOS 7. Since there is no GNOME environment on the CentOS side, the display of the virtual host on VirtualBox was displayed with X11 Forwording, Since the screen transition is very slow, I set it so that the screen of the virtual host can be displayed using Windows RDP. In particular, the performance on the installer screen before the virtual host network was opened was improved. (When entering the administrator password and IP address, there was a tight typing time lag for each character.)
First, an Extension Pack is required to use the remote display of the virtual host on VirtualBox with RDP. Download from the following site https://www.virtualbox.org/wiki/Downloads
# VBoxManage extpack install Oracle_VM_VirtualBox_Extension_Pack-5.0.24-108355a.vbox-extpack 0%...10%...20%...30%...40%...50%...60%...70%...80%...90%...100% Successfully installed "Oracle VM VirtualBox Extension Pack".
Confirm that it is working
# VBoxManage list extpacks Extension Packs: 1 Pack no. 0: Oracle VM VirtualBox Extension Pack Version: 5.0.24 Revision: 108355 Edition: Description: USB 2.0 and USB 3.0 Host Controller, Host Webcam, VirtualBox RDP, PXE ROM, Disk Encryption. VRDE Module: VBoxVRDP Usable: true Why unusable:
The port should not overlap with other services. address specifies the IP address of the physical host. To connect in the flow of terminal-> physical host-> VirtualBox-> virtual machine display
# VBoxManage modifyvm ESXi6.0u2 --vrde on --vrdeport 33389 --vrdeaddress 172.20.20.166 --vrdereusecon on
The virtual machine "ESXi6.0u2" is now set up for remote display.
Start with the following command.
# VBoxHeadless --startvm ESXi6.0u2 Oracle VM VirtualBox Headless Interface 5.0.24 (C) 2008-2016 Oracle Corporation All rights reserved. VRDE server is listening on port 33389.
Thank you very much. It was very easy to understand. http://n73.jugem.jp/?eid=66
