Satimis, after you think you've installed the Guest Additions in a VM, open a log and search for this text:

VMMDev: Guest Additions information report: Version

That line will tell you what version Guest Additions is running, if any. The version should match the Virtualbox version you're running, seen in the first line of the log. If the version does not match, or the line does not appear in the log, the Guest Additions did not update.

Hi scottgus1

Thanks for your advice.

Regarding;

Code: Select all

File sharing between Host and CentOS 8 VM still doesn't work
I solved the problem by;

Code: Select all

$ sudo nano /etc/group
add satimis at end of following line

Code: Select all

vboxsf:x:973:satimis
Reboot CentOS 8 VM. Then files sharing between Host and CentOS 8 VM works
