nested virtualization and promiscuous mode
by P F
I want to run a VM, which will itself be the KVM host of a number of KVM guests.
Each of the guests running in that nested environment will have a vNIC with an IP address on the same subnet as the top-level hypervisor (the ovirt node).
In VMware vSphere environments I was able to do this by enabling promiscuous mode and forged transmits on the VMware distributed switch port group, as described in this medium article;
https://williamlam.com/2013/11/why-is-promiscuous-mode-forged.html
I've search a number of old threads here on the ovirt list archives. Many refer to vdsm hooks that don't appear to exist any longer in ovirt 4.5.1.
How can I accomplish the same thing in ovirt?

Furthermore, the issue i am having at the moment, i cant delete, edit disk. all the time i added another iso file to disk i got ERROR "paused by the system". And when i tried deleting the iso file, i still got another ERROR. "Finalizing Cleaning up" (For more than a week the status never changes)
Please how can i fix it.
I will be most grateful, if you can share with me any instance messenger (Skype, discord or telegram) for fast communications.
I need you advise on this issue.
