How to solve VirtualBox unable to install enhancement tools

Click “device” – “install enhanced features”, and then the following thing will pop up. Baidu and Bing have solved this problem for a long time~

Unable to insert the virtual optical disk D:\Program\Orade\VirtualBox\VBoxGuestAdditions.iso into the machine lubuntu1810.
Could not mount the media/drive 'D:\Program\Orade\VirtualBox\VBoxGuestAdditions.iso' (VERR_PDM_MEDIA_LOCKED).

1。 Install vboxguest additions manually

sudo mkdir --p /media/cdrom
sudo mount -t auto /dev/cdrom /media/cdrom/
cd /media/cdrom/
sudo sh

2。 Just restart the virtual machine


First, I manually installed VBox guest additions (but I didn’t try to pop up the CD before installation.) Then restart the virtual machine, you can paste, copy and drag files, the goal is achieved~

If you have doubts, you can try to pop up the CD first to see if you can install the enhancement. Click “device” – “install enhancement” , if not, you can install it manually

But! I don’t want to open windows sharing, so I’ll try to drag and drop files and copy and paste them directly. After all, this is my main purpose

As for how to check “use host I/O cache”, you can try it, but I’m not sure it can be used, because I can turn it off. Maybe this option is only needed to open shared folder, but I don’t need shared folder~

Virtual machine settings storage controller SATA check “use host I/O cache”

Storage controller SATA – click * *. VDI – check “solid state drive”

Restart the virtual machine system
