pxeboot with dnsmasq as dhcp proxy for rockylinux

first, I installed apache & started its service

yum install httpd && systemctl enabled httpd --now

then I mounted dvd iso & copied its content to apache dir

mount -o ro ~/Downloads/rockylinux9.iso /mnt/iso

cp -rv /mnt/iso/* /var/www/html/install-media/

and copied kickstart file under

cp ~/kickstart-rockylinux9.cfg /var/www/html/install-media/kickstart/

then I installed tftp-server & syslinux & started tftp-server

yum install tftp-server syslinux

then I created these dirs & copied kernel files to below path

mkdir -p /var/lib/tftpboot/{images,pxelinux.cfg}

cp /var/www/html/install-media/images/pxeboot/{vmlinuz,initrd.img} /var/lib/tftpboot/images/

then I copied menu files from syslinux dir

cp /usr/share/syslinux/{menu.c32,pxelinux.0} /var/lib/tftpboot/

finally created menu file /var/lib/tftpboot/pxelinux.cfg/default with below content

default menu.c32
prompt 0
timeout 300
ontimeout 2

menu title PXE Boot Menu
label 1
  menu label ^1 - Install Rocky Linux 9
  kernel images/vmlinuz
  append initrd=images/initrd.img showopts method=http://192.168.1.254/install-media/  devfs=nomount ks=http://192.168.1.254/install-media/kickstart/kickstart-rockylinux9.cfg 

Now the critical part is dnsmasq.conf, as my physical host is on bridged network with kvm installed on it. so dnsmasq is supposed to proxy dhcp request to my router

# cat /etc/dnsmasq.con

# Enable proxy DHCP for PXE
port=0
dhcp-range=192.168.1.0,proxy
# Specify PXE options
dhcp-boot=pxelinux.0,,192.168.1.254
enable-tftp
tftp-root=/var/lib/tftpboot

here's my kickstart file

I am unable to boot, after getting IP info properly from dhcp it says, No boot devices found.
