After vm is running, check the ifcfg-ens192 file, it's not configured as expected.

[core@compute-overwrite ~]$ cat /etc/sysconfig/network-scripts/ifcfg-ens192 
# Generated by dracut initrd
NAME="ens192"
DEVICE="ens192"
ONBOOT=yes
NETBOOT=yes

IPV6INIT=yes
BOOTPROTO=dhcp

The setting for /etc/hostname works.
[core@compute-overwrite ~]$ cat /etc/hostname

Additional info:
Compare with rhcos-410.8.20190516.0, no such issue, /etc/sysconfig/network-scripts/ifcfg-ens192 is not pre-existing in image, so ignition could successfully create ifcfg-ens192.
