<div dir="ltr">Hi everyone<div><br></div><div>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.<br></div><div><div>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).</div>
<div><br></div><div>In the host machine, I have the same infrastructure.</div><div><br></div><div>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.</div>
<div><br></div><div>My question is: is it possible to use libvirt in this scenario?</div></div><div><br></div><div>Here are some messages:<br></div><div>- Libvirt log on centoOS (XCP VM):</div><div><div style="font-family:arial,sans-serif;font-size:13px">
