Hi everyone
I'm trying to create a virtual machine using OpenNebula [1] on a centos 6.4 server, but i'm facing some erros using kvm / libvirt.
This server is running on a virtual machine created on XCP. Then, my infrastructure is: XCP 1.6 (hypervisor - dom0) + CentOS 6.4 (running on a XCP VM) + OpenNebula 4.0.1 (installed on CentOS).
In the host machine, I have the same infrastructure.
The problem I'm facing is that, by following the tutorial [2], i've noticed that neither the parameter 'vmx' nor 'svm' is listed on the CPU information provided by the virtual machine where the centOs is running. However, if i run the same command in XCP hypervisor, the parameter 'vmx' is listed. That is, the CPU informations provided by XCP are different from those provided by its virtual machines.
My question is: is it possible to use libvirt in this scenario?
Here are some messages:
