[Users] Ovirt Node :: Nested virtualization
Hello everybody, I'm trying to enable nested virtualization on a physical ovirt node v2.5.5. What I want is to run L1 ovirt guest vms that expose intel's vmx feature. I've enabled nested virtualization via kvm-intel nested=1 on my physical node, yet, when I create and run a guest vm on that node, there's no vmx extension/feature on the virtualized cpu. I've also fiddled a bit with the vdc_options table, ServerCPUList option, to no avail. I just need to tell ovirt to add the vmx extension to the virtualized cpu features when it creates a guest, is there a way to do this? In libvirt terms: cpu match='exact' modelPenryn/model vendorIntel/vendor feature policy='require' name='vmx'/ /cpu Thanks, Daniele Pavia ___ Users mailing list Users@ovirt.org http://lists.ovirt.org/mailman/listinfo/users

It's not well tested at the moment, though, and you may have other issues with nested virt specifically. You would also need to do some custom work that would enable nested virt in the kernel options as well since it is disabled by default. Getting this to work across reboots would require some additional effort. At this time, you'd generally be better off using Fedora as your host. You can also file an RFE bug to allow nested virt on ovirt-node.
