You can manually remediate virtual machines against the predefined individual virtual machine baselines or a virtual machine baseline group containing VMware Tools and VM Hardware upgrade baselines. You can also schedule a remediation operation at a time that is convenient for you.
To remediate multiple virtual machines simultaneously, they must be in one container, such as a folder, vApp, or a data center. You must then attach a baseline group or a set of individual virtual machine baselines to the container.
In the vSphere Client, virtual machine remediation is replaced by upgrading. You can upgrade VMware Tools and VM Hardware.
With Update Manager you can remediate templates. A template is a copy of a virtual machine that you can use to create and provision new virtual machines.
You can set up automatic upgrades of VMware Tools on power cycle for virtual machines. For more information, see Upgrade VMware Tools on Power Cycle in the vSphere Web Client and Automatically Upgrade VMware Tools on Reboot.
Update Manager does not support virtual machine patch baselines.
If a host is connected tovCenter Server by using an IPv6 address, you cannot scan and remediate virtual machines that run on the host.
