Getting error while deploying new VM in 5.02 and CentOS7


please, check:

  • you have enabled Virtualization (VT-x or AMD-V) in the computer BIOS
  • the CPU flags, should then contain virtualization flags, please try:
  • for Intel: grep vmx /proc/cpuinfo
  • for AMD: grep sv /proc/cpuinfo
  • the KVM modules are loaded (kvm_intel for Intel or kvm_amd for AMD)

Most likely the first point is the root cause here.

Thanks. I am able to figure it out. I am using nested virtualization. ESXi are base hypervisior layer and on the top of it i had build Opennebula using CentOS 7. I had forgot yo enable VT at ESX level for the CentOS machine.
