This video demonstrates how to update patches on an ESXi 5.x/6.x host using “esxcli software vib” commands. Patches can either be installed or updated on an ESXi host using esxcli vib commands.
Caution: The install method has the possibility of overwriting existing drivers. If you are using third-party ESXi images, VMware recommends using the update method to prevent an unbootable state.
Patches for VMware products can be downloaded from the following location

This video demonstrates how to backup and restore an embedded vCenter Server 6.0 vPostgres database. Backing up your database protects the data stored in your database. Of course, restoring a backup is an essential part of that function.
This follows up on our recent blog & video: How to backup and restore the embedded vCenter Server Appliance 6.0 vPostgres database
Note: This video is only supported for backup and restore of the vPostgres database to the same vCenter Server. Use of image-based backup and restore is the only solution supported for performing a full, secondary appliance restore.

This video demonstrates how to troubleshoot “SSO log directory full” warnings in vCenter Server Appliance 6.0. This is a known issue affecting vCenter Server Appliance 6.0, and currently, there is no resolution. You see that the /storage/log directory is highly utilized in an Embedded vCenter Server Appliance or Platform Controller Server Appliance 6.0.
To work around this issue, reduce the maximum backup size and the maximum backup index in the log4j.properties file.
Note: In external Platform Service Controller (PSC) environments, log in to the Platform Service Controller instead to make the suggested changes.

This video demonstrates how to install Windows guest operating system using the Easy Install feature in VMware Fusion.
Before creating a virtual machine, you must obtain the operating system and any necessary product keys for installation in that virtual machine. VMware Fusion does not come with any operating systems to install in virtual machines you create.
This method assumes that you are using a physical CD or a disk image (.iso / .cdr /.dmg file). You cannot create a Windows virtual machine by using .exe files downloaded from Microsoft, as those files need to be run on a Windows PC.
