RHEL KVM VM Network Configuration

Hi,

Just want to understand if any of you encounter the same issue i have encountered

i had deployed RHEL + KVM (RHEL 7.9) and configured a bridge network on the OS Level side. I also deployed a linux VM on top of this configuration. The initial setup was fine.

After a while, i need to change my subnet so i need to change the IP address of the RHEL KVM and the linux VM on top.

The RHEL KVM is now accessible to the network using the new IP with the previous bridged network.
Unfortunately the Linux VM does not have any access on the network. The VM cannot ping the KVM and vice versa.

I am not sure if i need to reconfigure the bridge or must be the limitation since my environment is running on old RHEL 7 Machine.
Any one have resolution to this?
