Centos8 does not have "network scripts" installed,But you can install it manually
dnf install -y -q network-scripts
systemctl disable NetworkManager
systemctl enable network-scripts
systemctl start network-scripts
After network scripts is started, the files you need will be created automatically under /var/lib/dhcp/

HI Hean
Network manager supports three ways to get DHCP: dhclient, dhcpcd and internal;
rhel7/centos7 default is dhclient
centos8 default is internal;
Cloud init and cloudstack password scripts depend on dhclient;
So we need to modify / etc / network manager/ NetworkManager.conf
[main]
##Add the following section
dhcp=dhclient

Re: Password reset for CentOS 8 Template

Hi Hean,
I had seen a similar behavior with VMs deployed on shared network. The issue was that cloud-init first searches for the dhcp leases file, and only if it can't find one does cloud-init use the default gateway to reach the metadata server.
So, firstly you may want to check for the presence of the dhclient lease file, which contains the parameter - 'dhcp-server-identifier' which would correspond to the VR IP. If it isn't present, you could try to acquire the lease by running ' dhclient -1' and then try resetting the password.
Thanks
Pearl

Re: Password reset for CentOS 8 Template
Posted by Craig Dunn <se...@googlemail.com.INVALID>.
Hey,
I created a Centos 8 template a few months back for our cloudstack 4.11
install.
I made a few notes on the install, Not sure exactly what issue you were
having but mine was the script tried to run before network manager had
finished starting. Notes I made I pasted below, hope it helps
Centos 8 and above has changed the way in which its networking is handled.
The Network-Scripts has been deprecated and replaced with Network Manager
which handles all interfaces
This means that placing the Cloudstack password management script inside
/etc/init.d errors saying that Network Manager was not started. This is due
to the fact that the script runs on bootup and runs before Network Manager
starts so the password does not get changed.
If you try this you can see the error in /var/log/messages and you run:
cat messages | grep "password"
To resolve this we need to get the password change script to run after the
Network Manager service has started.
Navigate to /etc/NetworkManager/dispatcher.d
Create a file called ifup-local
And paste the script inside the file
Thanks
