I installed PowerVC x86 on VMware

Note: PowerVC uses the default network interface: eth0. To use a different network interface, set the environment variable, HOST_INTERFACE, before running the install script. For example: export HOST_INTERFACE=eth1.

Once Redhat 8.4 is installed, change the ethernet adapter name

Change from ens192 to eth0

[root@ibmpvc01 ~]# lshw -class network -short
H/W path             Device      Class          Description
===========================================================
/0/100/16/0          ens192      network        VMXNET3 Ethernet Controller

Add the option net.ifnames=0 into file /etc/default/grub, and rebuild grub, then reboot

[root@ibmpvc01 ~]# cat /etc/default/grub
...
GRUB_CMDLINE_LINUX="crashkernel=auto resume=/dev/mapper/rhel-swap rd.lvm.lv=rhel/root rd.lvm.lv=rhel/swap rd.lvm.lv=rhel/usr net.ifnames=0 rhgb quiet"

[root@ibmpvc01 ~]# grub2-mkconfig -o /boot/grub2/grub.cfg
[root@ibmpvc01 ~]# init 6

After reboot

[root@ibmpvc01 ~]# lshw -class network -short
H/W path             Device      Class          Description
===========================================================
/0/100/16/0          eth0        network        VMXNET3 Ethernet Controller
