Could you list which elements of a typical vmware setup that utilises vcenter esxi and windows guests require patching? So vcenter patching, host patching, and guest patching, specific the vmware what needs patching, and any idea on the frequency of the patches released?

Security Updates (patching)

1. Windows Guests (every month, when Microsoft release patches on Patch Tuesday)

2. vCenter Server (new versions e.g. 4.1 U2, 5.0 U1) VMware very seldom releases patches for vCenter Server, but releases new builds, so you can do a complete upgrade. As for timescales, vSphere 5.0 Update 1  Released 15 Mar 2012, vSphere 5.0 | Released 24 Aug 2011

3. Hypervisor Updates (ESXi), Security Updates and Fixes are issued.  If we look at ESXi 5.0

there have been several patches

Build Number: 474610 Release Date: :  09/13/2011 (patches to ESXi 5.0)
Build Number: 504890 Release Date: :  11/03/2011 (patches to ESXi 5.0)
Build Number: 515841 Release Date: :  12/15/2011  (patches to ESXi 5.0)
Build Number: 623860 Release Date: :  03/15/2012 (this is ESXi 5.0 U1)

All patches can be checked here

http://www.vmware.com/patchmgr/download.portal 

So with the Hypervisor, it could be a patch every month from release.

Is there anything vmware specific on the guests that needs patching from vmware? Your 1 seems specific to MS updates nothing on guests around vmware.

Cheers!

You should also check for firmware/BIOS updates for the hardware running this environment.

Re 1: Each VM will have "VMWare Tools" installed, providing enhanced drivers for Video, Network, Mouse etc.

You generally only have to update this with every major VMWare update

every host update may have a new version of vmware tools, which could be applied to the guest vms.

And is there 1 tool that can patch all 3 (vCenter, Host, vmware tools on guest) and provide management overview on whats at what level, whats missing what patch? If there is 1 tool a copy or screenshot of a sample report would be ever so helpful!

No not really, VMware Update Manager patches the host.

Would update manager show which hosts are missing patches? Is it a report format thats management freindly?

Yes, Update Manager would show which updates. VMware issues Security Updates, which changes the Build Number of the OS, you could say a change of service pack. A Security Build Update contains many security fixes and bug fixes.

I do not think the Report is management friendly.

Would you be willing to share a screenshot of a report for reference?

Also > where can you see the build number? And where can you see from vmware the latest build numbers.

Is update manager part of vcenter, or an additional tool that requires additional $$

And are the patches released for vmware tools on guests security related, or something else? How often are they released?

Ive never seen any VMware Tools updates on their own.

Tools are sometimes included with host updates, eg new host update, it may have new tools as well.
