Enabling Intel VT and Non-Execute Memory Protection for VMware EVC

I have faced this issue after integration of new server in our current vmware production cluster.
This leads to incompatibility problem with your current HA cluster as you can perform VMotion with below  error message:


A simple way to fix this issue is by masking NX/DX bit for the virtual machine.
To permanently fix this issue you will require to Enable Interl (R) Virtualization Technology (VT) and Non-Excecute Memory Protection in BIOS.

To do this you have:


  1. Migrate all running VMs in the  concerned Esx server.
  2. Put the Esx server in maintenance Mode.
  3. Reboot the Esx server.
  4. While the server is initializing Press < F9 > to Boot in the Bios and go to "Advanced Option " Menu. 


         5. Select "Processor Options"


           6. Select "No-Execute  Memory Protection"  and  enable it.


            
            7. Enable Intel (R) Virtualization Technology.


             8.  < F10 > to save and Exit.


Once you Exit , the Esx  server will reboot.

Now you can doing Vmotion migartion between your Esx server also you can configure EVC in your cluster.

What You Must Know Before Establishing a Recovery Plan ?

In today's rapidly evolving digital landscape, organizations are increasingly adopting the zero trust model, primarily due to the expanding attack surface that leaves critical systems and data exposed. This shift is also fueled by the heightened sophistication of cyber-attacks, which have become more complex and harder to detect, surpassing traditional security measures. Additionally, the existing operating models within organizations are often inconsistent, typically characterized by distributed and siloed environments.    This fragmentation creates vulnerabilities and makes it challenging to implement uniform security protocols. The zero trust model addresses these challenges by assuming that threats exist both inside and outside the network, necessitating continuous verification of all users and devices. Its adoption represents a proactive stance in the ongoing battle against cyber threats, ensuring a more robust and resilient organizational security posture. The Evolution ...

A comprehensive guide to ransomware distribution in VMware environments

In a virtualized on-premises environment based on VMware, ransomware distribution scenarios can be somewhat unique due to the nature of virtualization technology. However, many of the traditional attack vectors still apply. Here are some ransomware distribution scenarios specific to a VMware-based virtualized environment: Phishing Attacks Targeting Administrators: Administrators with access to the VMware environment might receive phishing emails. If they fall for these and their credentials are compromised, attackers can gain access to the virtualized environment. Exploiting Vulnerabilities in VMware Software: If VMware software or the underlying operating system is not kept up-to-date with security patches, vulnerabilities can be exploited by attackers to deliver ransomware into the virtualized environment. Compromised Remote Management Tools: Tools used for remote management of the virtualized environment, such as vSphere, can be a target. If these tools are compromised, attackers ca...

Edge Computing Demystified Book

After a while I'm back and pleased  to share in this post my first book around Edge computing Technologies. Edge computing has been a very hot and interesting topic nowadays for communication service provider and Enterprise so far. Augmented Reality / Virtual Reality, Smart cities, Healthcare, industrial IoT and many others use cases require a change in the way we operate and host application in the cloud.  IA, Big Data and analytics are often used today to understand the behavior of the customer and even the health of services. Real-time and high throughput demand are the characteristic of the new business services. Edge computing technology promises to resolve different challenges and brings compute, storage and bandwidth close to the data source. I tried in ‘the Edge Computing Demystified’ book to explain Edge computing technology referring to different use cases from communication service provider and enterprise industry. I h...
