Changing VMware Storage Controller to Paravirtual for CentOS 7

In this post, we are going to change the Virtual Storage Controller from LSI Logic Parallel to VMware Paravirtual for a CentOS 7 based Virtual Machine that is running on VMware vSphere. This blog post will contain step by step guidance for performing the operation.

In my case the virtual machine was build in VMware Workstation and after some time migrated to VMware ESXi. The VMware Paravirtual Storage Controller is not supported in VMware Workstation. That is why the virtual machine came over with the “wrong” storage controller.

My 24×7 Lab environment is running shared iSCSI based storage and all virtual machines are thin provisioned. The Virtual Machine that came over from VMware Workstation is installed with CentOS 7.

Why VMware Paravirtual?

Why should you want to migrate from an LSI Logic Parallel to a VMware Paravirtual SCSI Controller? Two simple reasons and it are two good ones:

  • Lower CPU utilization
  • Higher Throughput

Personally, I have a third reason to add… compliance. All my virtual machines should be compliant with the VMware Best Practice and my personal Home Lab standard. In my Lab environment, this means using the VMware Paravirtual where ever possible/supported.

VMware Official Statement 1:

PVSCSI adapters are high-performance storage adapters that can result in greater throughput and lower CPU utilization. PVSCSI adapters are best for environments, especially SAN environments, where hardware or applications drive a very high amount of I/O throughput. The VMware PVSCSI adapter driver is also compatible with the Windows Storport storage driver. PVSCSI adapters are not suitable for DAS environments.VMware Paravirtual SCSI adapters are high-performance storage adapters that can result in greater throughput and lower CPU utilization.

VMware Official Statement 2:

The PVSCSI adapter offers a significant reduction in CPU utilization as well as potentially increased throughput compared to the default virtual storage adapters, and is thus the best choice for environments with very I/O-intensive guest applications.



Procedure

The most important step in the process is to make sure you have a valid backup! After that, it is just following the steps described below:

  • Create a virtual machine snapshot or backup before you begin.
  • Power-off the virtual machine.
  • Add the VMware Paravirtual Controller to the Virtual Machine. Do not change the disk controller assignment yet, only add the storage controller to the VM (screenshot 01).
  • Power-on the virtual machine.
  • Login with an account on the virtual machine (account must be able to obtain root access).
  • Start rebuilding the initial ramdisk image (screenshot 02):
    mkinitrd -f -v /boot/initramfs-$(uname -r).img $(uname -r)
  • Power-off the virtual machine.
  • Assign disks to the new storage controller and remove the old storage controller (screenshot 03).
  • Power-on the virtual machine.
  • Validate that everything is working and disks are mounted (screenshot 04).
  • Remove the virtual machine snapshot or backup after you are done.

Screenshots

Conclusion

At this point, I have swapped out three virtual machines from the LSI controller to the VMware Paravirtual SCSI Controller. The machines have been running now for about two weeks without any problems. So everything is compliant again ;).

Deployment of VMware vCenter Server 6.7 Update 1

In this blog post, we are going to deploy VMware vCenter 6.7 Update 1 in my Lab environment. The deployment is fully covered with all the additional notes required to perform a successful installation, migration or upgrade. I also added some guidelines for designing your environment.

Now that vSphere 6.7 Update 1 is available since the announcement on VMworld 2018 US, it is a good time to start looking at vSphere 6.7 instead of vSphere 6.5.

Why should you look at vSphere 6.7 you might ask? vSphere 6.5 is still running like a charm! Yes you are correct but… there are a couple of items to consider:

If you are familiar with the VMware vCenter 6.5 graphical deployment it has been improved in VMware vCenter 6.7. In the past it was a web-based wizard, with 6.7 it is a binary executable. This means a lot faster and better-responding interface and it removes the browser dependency and browser plug-in on your workstation.



Checklist

The checklist items can be verified, days or hours before the initial deployment. If you don’t have a plan before installing, migrating or upgrading things will turn out ugly…

With the checklist, you can determine if your environment is ready for vSphere 6.7 Update 1. It’s about checking and validation your current software and hardware and talking to your vendors about compatibility.

I have also added some design decision ideas. Because you can choose to install, upgrade or migrate without looking at your current architecture but maybe it is time to update your current architecture (design).

  • Make sure that all connected/used VMware products are compatible like (vRealize Automation / vRealize Orchestrator / vRealize Operations Manager / VMware Horizon and the list goes on). This can be verified on the VMware Product Interoperability Matrices page.
  • Make sure that all third-party products are compatible like (Backup & Replication software / Storage vendor software).
  • Determine the correct sizing for your environment. How many virtual machines and ESXi Hosts are going to be running underneath this vCenter Server. These figures determine your vCenter Server size.
  • An embedded Platform Services Controller (PSC) is the way to go in the future. An external Platform Services Controller will not be available anymore in the future.
  • Where is Windows? Please read this article from more than one year ago. Please do not deploy a vCenter Server on Windows. This is a thing of the past.
  • Verify the Hardware Requirements for the vCenter Appliance (depending on your chosen size and internal or external PSC).
  • Do you deploy against an ESXi Host or a vCenter Server?
  • Is your ESXi host hardware compatible with vSphere 6.7 Update 1?

Preparation

The checklist is completed and you have determined that everything is working or is acceptable to continue. Let’s start with some basic stuff that is required:

  • Read the release notes (VMware vCenter Server 6.7 Update 1 Release Notes).
  • Download the latest release from the VMware website.
  • Create firewall rules for your new vCenter Server.
  • Create forward and reverse DNS records in your DNS Server.
  • Register your IP information in your IPAM system.
  • Save your passwords in your Password Management system (Appliance password / SSO password).
  • Have a workstation ready to perform the deployment with sufficient network access and administrative rights.

Deployment

Let’s start the deployment of VMware vCenter 6.7 Update 1. I have chosen for a clean installation of VMware vCenter 6.7 Update 1. I have chosen for an embedded Platform Services Controller (PSC). Based on my total amount of virtual machines and ESXi Hosts I have selected a “Small” installation footprint.

The new deployment process for vCenter Server 6.7 Update 1 consists out of two stages, one is the deployment stage and one is the setup stage.

The first part is mainly responsible for delivering the full appliance with the operation system, network settings, and installation application bundles. The second part is configuring the applications that are running on the vCenter Server. A total installation takes about 45 minutes to complete.

Procedure:

  1. Mount the vCenter Server media (iso file).
  2. Navigate to the following path “X:\vcsa-ui-installer\win32\” (X stands for the CD-ROM drive label).
  3. Run the following application “installer.exe“.
  4. Follow the wizard, I have uploadedall screenshots for reference.

Stage 01 – Deployment

Here are the images of the first stage of the deployment of VMware vCenter 6.7 Update 1. I have no issues to report everything was working fine on the first try!

Stage 02 – Setup

Here are the images of the second stage of the deployment of VMware vCenter 6.7 Update 1. This part was also bug-free, so it was a good deployment.



Configuration

After a successful deployment of the VCSA appliance, you need to configure at least some items to get vCenter Server production ready. The items listed below are a basic set of the most common items I see in the field:

  • Install the vCenter Server License.
  • Active Directory.
  • Assign rights & permissions.
  • Generate and installation of SSL Certificates.
  • Connect the required VMware products and third-party systems.
  • Create a datacenter object.
  • Create a cluster object.
  • Create a distributed switch.
  • Join ESXi Hosts to the newly created cluster.

Lab Environment

So how does my Lab environment look like?

  • VMware vCenter 6.5.0 Update 2. The target for the vCenter 6.7.0 Update 1 deployment.
  • VMware ESXi 6.5.0 Update 2 in the 24×7 environment. Known as the production cluster.
  • VMware ESXi 6.5.0 Update 2 in the Lab environment. Known as the lab cluster.

You might ask… why don’t you upgrade the current vCenter Server? Good question! The machine has been converted/upgraded multiple times. It started out in life as a VMware vCenter 5.5 machine, that was on the Windows Server 2012 platform. So it was a good moment to start clean after this many years.

The VM Remote Console changed to VMware Workstation instead of VMRC

Lately, I discovered an annoying feature in combination with VMware vCenter and VMware Workstation. When installing VMware Workstation on your management computer it becomes the default Remote Console viewer. To be honest, I like the VMware Remote Console (VMRC) very much. The application has all the features and is quick and light. This compared to starting VMware Workstation to open a Remote Console.

What is VMware Remote Console: “The VMware Remote Console (VMRC) is a standalone console application for Windows. VMware Remote Console provides console access and client device connection to VMs on a remote host. You will need to download this installer before you can launch the external VMRC application directly from a VMware vSphere or vRealize Automation web client.”

In October 2017, I already fixed my problem on my management computer… but after a recent VMware Workstation update, it changed the Remote Console back to VMware Workstation. Currently, there is no option in the GUI to change the default Remote Console. Ok, but how do we get VMRC back?

When I was comparing the Windows Registry, I found out that the following registry keys were different between machines. To speed up to process I created some PowerShell one-liners to fix the problem.

### View settings in registry
Get-Item HKLM:\SOFTWARE\Classes\vmrc\DefaultIconGet-Item HKLM:\SOFTWARE\Classes\vmrc\shell\open\command

### Change settings to VMRC
Set-Item HKLM:\SOFTWARE\Classes\vmrc\DefaultIcon -Value '"C:\Program Files (x86)\VMware\VMware Remote Console\vmrc.exe",0'
Set-Item HKLM:\SOFTWARE\Classes\vmrc\shell\open\command -Value '"C:\Program Files (x86)\VMware\VMware Remote Console\vmrc.exe" "%1"'

When you change the registry keys, the settings are direct in effect. No Operating System reboot or browser restart is required. The change is instant. I hope the blog post helps some vSphere Administrators that also prefer VMRC above VMware Workstation for viewing Remote Consoles.

@VMware: I would like to have an option to control the behaviour without changing registry keys by hand… 🙂 Thanks!



Environment

The issues occurred with the following combination of software:

  • VMware vCenter Server 6.5 (Update 1e)
  • VMware VMRC (10.0.2-7096020)
  • VMware Workstation (12.5.9 build-7535481)
  • Management Workstation: Windows 10 X64

VMRC Screenshots

Automated installation with VMware ESXi 5.5/6.0/6.5

In this blog post, we are going to automate the installation of VMware ESXi 5.5, 6.0 and 6.5. This can be done with a so-called “kickstart” configuration file which is officially supported by VMware. The file contains the configuration for a VMware ESXi Host to configure settings like IP address, subnet mask, hostname, license key, datastore, etc.

The kickstart configuration file can be made available in the following locations:

  • FTP
  • HTTP/HTTPS
  • NFS Share
  • USB flash drive
  • CD/DVD device

Personally, I prefer to use the HTTP protocol.



Use Case

You might ask yourself, why should I install an ESXi Host with a kickstart file? Some of the use cases I identified over the years are:

  • The very first ESXi Hosts for your SDDC environment (before VMware vCenter is deployed or vSphere Auto Deploy is configured).
  • A standalone ESXi Host for a small environment.
  • A Home Lab environment to install nested VMware ESXi Hosts.

Setup a web server

To make the kickstart configuration file available for the ESXi host we need a web server. Basically, every web server available on the market can serve this file. Here is a list of web server products that I have used: Apache, Microsoft IIS and NGINX.

In this environment/example I used a Microsoft IIS server on a Windows 10 Client. Do not forget to add the cfg extension to the MIME types.

Configuration file

Now it’s time to create a text file with your favourite text editor. The text file in this example is called (ks.cfg). I have added two configuration files as samples, one with the minimum settings and one I normally use for my Lab environment.

Configuration file – Simple (ks.cfg)

This is a default ks.cfg configuration file with just the minimum of settings required.

#
# Sample scripted installation file
#
 
# Accept the VMware End User License Agreement
vmaccepteula
 
# Set the root password for the DCUI and Tech Support Mode
rootpw mypassword
 
# The install media is in the CD-ROM drive
install --firstdisk --overwritevmfs
 
# Set the network to DHCP on the first network adapter
network --bootproto=dhcp --device=vmnic0
 
# A sample post-install script
%post --interpreter=python --ignorefailure=true
import time
stampFile = open('/finished.stamp', mode='w')
stampFile.write( time.asctime() )

Configuration file – Advanced (ks.cfg)

This is the more advanced version of the configuration file that also configures a lot of other settings like NTP servers, search domain, CEIP and a static IP address for the management interface.

    ### Reboot
    esxcli system shutdown reboot -d 15 -r "rebooting after ESXi host configuration"


Installing an ESXi Host with Kickstart file

The following procedure needs to be performed to boot from a kickstart file:

  1. Boot the ESXi host with a VMware ESXi ISO (ISO file can be obtained from the VMware download page).
  2. Press the key combination “shift + o” at boot.
  3. Enter one of the following lines after runweasel:
    • For an HTTP share: ks=http://%IP_or_FQDN%/kg.cfg
    • For an HTTPs share: ks=https://%IP_or_FQDN%/kg.cfg
    • For a NFS share: ks=nfs://%IP_or_FQDN%/ks.cfg
  4. The installation will start and use the kickstart configuration file (ks.cfg).
  5. After the installation is complete the ESXi Host will reboot.
