I was already guessing that it is not supported. Thanks for the
"official" confirmation.

OK, I've populated the required files...
/etc/modules-load.d/dummy.conf
/etc/modprobe.d/dummy.conf
/etc/sysconfig/network-scripts/ifcfg-dummy0
...and after a reboot I have a new dummy NIC configured:
dummy0: flags=195<UP,BROADCAST,RUNNING,NOARP> mtu 1500
inet 192.168.0.254 netmask 255.255.255.0 broadcast
192.168.0.255

Unfortunately, this does not work as described. I was able to create
the new VM network from the Admin Portal successfully, but I am unable
to attach this network to the dummy NIC.
When I choose the "Setup Host Networks" option from the Admin Portal:
My Datacenter => My Cluster => Hosts => My Host => TAB: Network
Interfaces -> Setup Host Networks
The dummy NIC is NOT listed, but only the physical NIC (with ovirtmgmt
attached to it).
Is this expected? Does oVirt suppress any non-physical NICs?
Is there another way to attach the VM network to my dummy NIC?
Thanks
