Have you tried with Network Manager , after all this is the thing that manages all networks:
[root@system ~]# nmcli connection add con-name dummy0 ifname dummy0 type dummy Connection 'dummy0' (9fdd74fa-c143-4991-9bac-0e542704ac89) successfully added.
[root@system ~]# reboot Shared connection to glustera closed.
[root@system ~]# nmcli connection show NAME UUID TYPE DEVICE dummy0 9fdd74fa-c143-4991-9bac-0e542704ac89 dummy dummy0
[root@system ~]# ip a s dummy0 3: dummy0: <BROADCAST,NOARP,UP,LOWER_UP> mtu 1500 qdisc noqueue state UNKNOWN group default qlen 1000 link/ether ce:c9:83:97:10:ee brd ff:ff:ff:ff:ff:ff inet6 fe80::599:a978:9457:df10/64 scope link noprefixroute valid_lft forever preferred_lft forever

Anyone have any ideas? It's rather annoying that I can't get these to persist across reboots without using some kind of helper script.

Hello all, hoping someone can help me out here.
I cannot get dummy interfaces on a new Cent8 build to persist across reboots.
On Cent7 - this is the process I use:
Create Dummies: # cat /etc/modules-load.d/dummy.conf dummy # cat /etc/modprobe.d/dummyopts.conf options dummy numdummies=4 # ip link add dummy0 type dummy ## - repeating a/ ascending dummyN adapters for as many needed # service network start # dracut -f
Now this was different than even how 6 handled it, forget how I finally dug that up (possible I even asked here). I've applied this same configuration to a Cent8 box I'm trying to stand up and it all appears to work fine, but unlike the Cent7 boxes, when the Cent8 box comes back up, all the dummy adapters are missing. I've been searching all over trying to find some documentation on this to no avail. I'm hoping someone has some suggestions here to help out.
Thanks, Frank
