I am running an ubuntu VM (instance 22.04) on Esxi 7.0 virtualized platform. 

I am trying to create Linux cloud images on this  ubuntu VM by installing virt-manager .. 

Reference: https://kifarunix.com/create-and-upload-custom-linux-image-into-openstack/?expand_article=1

But on my VM  when I execute 

grep -iE 'vmx|svm' /proc/cpuinfo
Returns 0   //means not CPU virtualization enabled ?    

modprobe: FATAL: Module l not found in directory /lib/modules/5.15.0-25-generic
root@ubuntu-VM:/home/ubuntu# lscpu |grep Virtualization
Virtualization type:             full



root@ubuntu-VM:/home/ubuntu#
root@ubuntu-VM:/home/ubuntu# grep -iE 'vmx|svm' /proc/cpuinfo
root@ubuntu-VM:/home/ubuntu# grep -c '(vmx|svm)' /proc/cpuinfo
0
root@ubuntu-VM:/home/ubuntu# grep -iE 'vmx|svm' /proc/cpuinfo
root@ubuntu-VM:/home/ubuntu#
root@ubuntu-VM:/home/ubuntu#


How can I enable the virtualization support on this   VM  ??   What to do for Nested Virtualization support  in this Virtual Machine ?

Any hints welcome. 

Thank you
