What is a VMware VIB and how do you install or uninstall it on an ESXi host?

A VIB consists of three main components: the payload (actual files such as drivers or modules), a descriptor file containing metadata and dependency information, and a signature file used to verify authenticity and trust level. VIBs are classified by acceptance levels such as VMwareCertified, VMwareAccepted, PartnerSupported, and CommunitySupported, indicating their validation status and production suitability.

To install a VIB, administrators first upload the file to an ESXi datastore using tools such as SCP clients. Then, using ESXCLI, they run:

For a ZIP depot:

esxcli software vib install -d /path/to/file.zip

For a standalone VIB file:

esxcli software vib install -v /path/to/file.vib

To uninstall a VIB, the command is:

esxcli software vib remove --vibname=

A host reboot may be required after installation or removal, depending on the package.

VIBs provide flexible, controlled extension of ESXi functionality while maintaining system integrity through signature verification.

Q1: Where can VIB files be obtained?

From official vendor websites or certified third-party hardware vendors.

Q2: Can you create your own VIB?

Yes, but it is not recommended for production environments.

Q3: Is ESXCLI the only way to install a VIB?

No, VIBs can also be installed through lifecycle management tools.

Q4: Do VIB changes require a reboot?

Some VIB installations or removals require a host reboot to take effect.
