virtualization – Troubleshooting KVM’s guest anaconda installer logs

I am trying to install RHEL7.9 KVM guest on Ubuntu 18.04 Azure VM. The anaconda installer fails due to some error but the virt-viewer screen got closed so fast, I was unable to read what is the exact error. I know all anaconda logs get stored in /tmp/anaconda.log file on the KVM guest disk image but I am unable to figure out a way to check the contents of the file.
I tried mounting the KVM guest disk image using “mount -o loop .img ” command but it fails with NTFS signature is missing, thats probably because the installation fails before the KVM guest’s disk is partitioned properly.
I am looking for ways to check the contents of that file. Is there any way to redirect the anaconda logs of the guest machine to the Ubuntu host machine ?
Pasting the virt-install script and kickstart file used. The RHEL7.9 installation media was downloaded from https://developers.redhat.com/products/rhel/download site.

virt-install.sh

             --disk /datadrive/rhel79-oracle-$1.img,size=40,format=raw 
             --os-variant rhel7.0 
             --initrd-inject ./ks-rhel79-oracle.cfg 
             --extra-args="ks=file:/ks-rhel79-oracle.cfg" 
             --vcpus 2 
             --memory 2048 
             --noreboot 
             --name rhel79-oracle-$1
