Hello ,
I have installed openNebula on standalone VM.
I have created 2-vms using open Nebula and i am able to login those vms.
But we unable to access internet on those VMs.
Can you please help here on this issue related to virtual networking.
HI @Vikas_Pawar, Welcome to the Forum! 
OpenNebula supports nested virtualization with KVM. For this, nested virtualization must be enabled on the physical host’s CPU.
Regarding the problem of not being able to access the internet from VMs created in OpenNebula it’s usually related to the virtual network configurations. OpenNebula uses different network models to manage virtual networks, and an incorrect configuration or the lack of a proper routing/NAT configuration can cause connectivity problems like the ones you are experiencing.
Which network driver are you using, can you share VM and vnet body information? onevm show -j <vmid> and onevnet show -j <vnetid> respectively.
Best,
Victor.
Thanks for quick response.
I have not yet enabled the nested virtualization on physical host.I will try enabling and let you know the status.
I have created linux bridge br0 and same using while creating virtual network.
Kindly find the attached output of commands onevm & onevnet.
