VMware: New Rollup Bulletins Simplify VMware ESXi Updating

July 14th, 2018 No comments

VMware ESXi patches are released periodically to resolve issues or address security vulnerabilities – just like any other software product. These updates can either be downloaded automatically through VMware vSphere Update Manager (VUM) or manually by logging in to My VMware. Regardless of delivery means, the contents are the same: a collection of software packages, knowns as VIBs, that are grouped into bulletins to ensure dependencies are satisfied during installation.

Bulletins, Patches, and Rollups

There are two different types of patch bulletins for VMware ESXi: patches and rollups.

For any given VMware ESXi patch release, there is typically, at a minimum, one bulletin that contains the core system packages – esx-base, vsan, and vsanhealth. Often, there are additional bulletins if other packages have been revised in order to remedy bugs or security issues. These types of bulletins, that include a small set of packages, are known as patches in Update Manager.

Occasionally, VMware releases a more comprehensive service pack, known as an Update, that includes the latest versions of all packages that comprise VMware ESXi. These Update releases are classified as rollups in Update Manager.

Rollup Bulletin Now Included in Every Patch Release

In between the large Update releases, however, there has not been a simple workflow for vSphere administrators to use that would ensure hosts are on the absolute latest version of every package. While this can be accomplished with dynamic Update Manager baselines that are configured to include all applicable patch bulletins, some customers may have opted to apply just specific critical patches. In that scenario, over time, hosts may lack many useful fixes and updates that were released since the GA.

Starting in June 2018, each VMware ESXi patch release will also feature an optional rollup bulletin that includes every package that has been updated since GA. This is a straightforward approach to keeping the vSphere infrastructure current, because the Update Manager baseline requires just a single bulletin.

For detailed information on software fixes, each VMware ESXi patch release is described in a KB article, with a link to a child article for each bulletin included in the patch release. Take a look at a recent VMware ESXi 6.7 patch KB for an example.

Takeaway

VMware issues a patch release when software fixes are required – these includes one or more bulletins. Each bulletin includes a set of VIBs, which are the ESXi software packages. Bulletins come in two different types: patch (a few packages) and rollup (complete system). Going forward, all patch releases will include the traditional patch bulletins, and will also be supplemented with a rollup bulletin. This offers a simple way to ensure hosts are running the latest version of every package.

VMware: Update or recover “root” password using Host Profiles

August 26th, 2014 No comments

Start Profile Wizard after you have entered Maintenance Mode

image

– Select: Create Profile from existing host

 

image

– Select host (in maintenance mode)

image

– Profile details: Reset root password

image

– Finish the host profile creation
On the left pane select your new host profile and right-click and select edit profile:

image

– Select: Root password reset > Security configuration > SSH authorized key for root user

Note: check or deselect specific host profile configurations to enable or disable them. A disabled configuration will not be applied when applying the host profile and hosts will not be checked for compliance with that configuration

Now click OK and we’ll start attaching the host of which we want to reset the password. Click ‘Attach Host/Cluster’ and select the right host, click Attach and then OK.

Voila, the root account of the host has been reconfigured and you should be able to log in again. Now the only thing left is to detach the host from the profile.

VMware: EVC – Method not found: ‘Vmomi.HostSystemArray EVCState.get_BadSoftwareHostsBlockingEVC()’

January 7th, 2011 3 comments

Today I got an error when selecting the “VMware EVC” option in the Cluster Settings at my vCenter 4.0 host with multiple HP Blades with same CPU. Error message:

Method not found: ‘Vmomi.HostSystemArray EVCState.get_BadSoftwareHostsBlockingEVC()’

VMpros.nl

 

Solution:

This issue occurs when a system installed with vSphere 4.1 and you use vSphere 4.0 Client on that system to access vCenter Server 4.0.

To workaround this issue, install a vSphere 4.0 Client on a system on which you have not installed vSphere4.1 Client earlier and then update the EVC cluster using the vSphere 4.0 Client.

VMware: Install in NagiosXI the VMware Plugin including VMware SDK

October 3rd, 2010 2 comments

I’m running NagiosXI in my testlab, to monitor my ESX hosts/VM’s I need to install the Nagios VMware Plugin. What did I do to realize the VMware host monitoring:

You need to install the SDK software.. download the VMware vSphere™ SDK for Perl download version: vSphere SDK for Perl – 32-bit Linux Installer because Nagios is running on a Linux 32-bit VM.

– Upload (with WinSCP) the extracted folder to the Nagios VM /tmp/ ;
– Dir to the folder: vmware-vsphere-cli-distrib ;
– Install the SDK: ./vmware-install.pl

VMware: How To Rollback ESXi 4.1 to 4.0 Upgrade

October 2nd, 2010 7 comments

Sometimes it is necessary to rollback an installation of VMware ESXi, reverting to a previous installation. Last weekend I did this for testing in my home lab. It’s pretty easy…

image

^ My upgraded VMware ESXi 4.1.0 Build 260247 server

 

image

^ Reboot the host and press SHIFT + H to revert the rollback. Message:

Current hypervisor will premanently be replaced with build: 4.0.0.-164009. Are you sure?

Press Y (or SHIFT + Y) to rollback the upgrade

VMware: How to create a bootable ESXi USB Stick with UNetbootin

September 3rd, 2010 14 comments

Last year we already posted about creating a bootable USB stick. In the last post we used WinImage to create the bootable USB stick to boot ESXi. Some time ago I found a tool which makes it much easier to create a bootable ESXi USB Stick. I am going to use UNetbootin to create bootable USB stick. You can download it here.

1. First connect the USB stick and start UNetbootinimage
