For my templates I use:

In kickstart files for CentOS 7 VMs that run in what I still think of
as runlevel 3, I use a somewhat simpler recipe:
bootloader --location=mbr --append="console=ttyS0"
On the VM, that translates into /etc/default/grub looking something
like this:
GRUB_TIMEOUT=5
GRUB_DISTRIBUTOR="$(sed 's, release .*$,,g' /etc/system-release)"
GRUB_DEFAULT=saved
GRUB_DISABLE_SUBMENU=true
GRUB_TERMINAL="serial console"
GRUB_SERIAL_COMMAND="serial"
GRUB_CMDLINE_LINUX="rd.lvm.lv=vg0/vmroot console=ttyS0 crashkernel=auto vconsole.font=latarcyrheb-sun16 vconsole.keymap=us"
GRUB_DISABLE_RECOVERY="true"
When the VM boots, it's then easy to run "virsh console YOURVM" to
attach to the serial console.
