Hum if I understand well and according your issue reported to launchpad.net https://bugs.launchpad.net/nova/+bug/1417201 You are trying to test hugepages under kilo which it is not possible since it has been implemented in this release (Juno, not yet published) I have tried to reproduce your issue with trunk but I have not been able to do it. Please reopen the bug with more information of your env if still present. I should received any notification from it. Thanks, s. > >BTW please verify your version of libvirt.
