VMware vCenter Update Manager Administration Guide vCenter Update Manager 4.0, page 11
Updates you specify can be applied to operating systems, as well as applications on scanned
ESX/ESXi hosts, virtual machines, and virtual appliances. With Update Manager, you can:
· Scan for compliance and apply updates for guests, appliances, and hosts.
· Directly upgrade hosts [B above], virtual machine hardware, VMware Tools, and virtual
appliances [C above].
· Update third-party software on hosts.
Update Manager can scan and remediate (update) powered on, suspended, and powered off
virtual machines, and templates [E above], in addition to scanning and remediating hosts. If the
upgrade or patching fails, you can revert the virtual machines back to their prior condition without
losing data. Update Manager can scan and remediate powered on, VMware Studio registered,
Red Hat, Ubuntu, SUSE, and CentOS Linux virtual appliances [Not Solaris so A is incorrect] . You
can deploy Update Manager in a secured network without Internet access. In such a case, you
can use the VMware vCenter Update Manager Download Service to download patch metadata
and patch binaries.
