Mount: you must specify the filesystem type

The following message is displayed when you attach an image file to a VM:

 

 

Two reasons are preliminarily determined:

1. the command "eject" is used when the disc is detached.

2. No optical drive/image files are attached to the virtual machine.

 

Solution:

VM-> setting-> cd/dvd-> device status-> connection ted

 

At this point:

 

OK!

Mounting the linux CD always prompts mount: you must specify the filesystem type

Your system cannot identify the data format in this disc.
It should not be said that this problem should not occur because the file system of the Linux system recognized the library for support by the iso9660 system for a long time.
Mount mounting is identified by this library.

You 'd better check the file system that your CD uses first. After confirming the mounting, set the mount file system type in the-t xxxxx mode.

However, the file systems iso9660 and udf should have been supported by default.

This error occurs when a CD is mounted in linux. How can you solve this problem? you must specify the filesystem

You must specify the format of your File System
Mkdir/mnt/media
Mount-t iso9660/dev/cdrom/mnt/media (iso9660 is the disc format)
Mount permission required
Are you sure you are root? Are you sure the device file corresponding to your optical drive is/dev/cdrom?
