I just completed #2 right now (yes, I'm starting from scratch) and the host shows: CentOS Linux 7 (Core) Kernel 3.10.0514.el7.x86_64 on an x86_64 I am following these instructions: http://www.ovirt.org/blog/2017/04/up-and-running-with-ovirt-4-1-and-gluster-storage/ Gianluca, thx for the detail

To install VDSM hook, I followed these instructions: http://community.redhat.com/blog/2013/08/testing-ovirt-3-3-with-nested-kvm/ Is this a proper way to do it? On 2017-05-30 09:54, Martin Polednik wrote: On 30/05/17 09:42 -0400, ov...@fateknollogee.com wrote: Host: CentOS-7_v1611 (or Fedora 25

But one of the questions already asked to you also throughout the other thread was: what hypervisor are you using? CentOS-7 v 1611 Question << What hypervisor should I be using?? More precisely, as it is clear it is Qemu-KVM, what is the way you start your VMs that are the candidates to beco

You need the VDSM hook (on the hypervisor) that sets up vmx feature Yes, I did that. use host passthrough mode for CPU where is this setting, this is on the VM in Virt-Manager? On 2017-05-30 09:54, Martin Polednik wrote: On 30/05/17 09:42 -0400, ov...@fateknollogee.com wrote: Host: CentOS-7

You need in the VMs to have the 'vmx' flag, if you are using libvirt you most likely should use 'host-passthrough' mode, otherwise nested virtualization might not work. Regardless of the emulated CPU type, you need to ensure 'vmx' flag is there, this can also be done explicitly in the libvirt XML.
