OS:                Arch Linux  
Hypervisor:        QEMU KVM  
Architecture:      x64
Machine Type:      qc35
EFI Firmware Code: /usr/share/edk2-ovmf/x64/OVMF_CODE.fd
EFI Firmware Vars: /usr/share/edk2-ovmf/x64/OVMF_VARS.fd

So I create a customized Arch Linux image using packer build and log my boot options.

output of echo ">>>> ${NAME_SH}: Show boot option.."

BootCurrent: 0001
    Timeout: 0 seconds
    BootOrder: 0007,0000,0001,0002,0003,0004,0005,0006

    Boot0005* UEFI PXEv6 (MAC:525400123456) PciRoot(0x0)/Pci(0x2,0x0)/MAC(525400123456,1)/IPv6([::]:<->[::]:,0,0){auto_created_boot_option}
    Boot0006* EFI Internal Shell    FvVol(7cb8bdc9-f8eb-4f34-aaea-3ee4af6516a1)/FvFile(7c04a583-9e3e-4f1c-ad65-e05268d0b4d1)
    Boot0007* GRUB  HD(1,GPT,2034b5d2-828a-4491-8d23-fe9439932a12,0x800,0x7d000)/File(\EFI\GRUB\grubx64.efi)

So I'm thinking that this should go fine, but instead when I run this:

virt-install command

sudo virt-install \
--name bastille-installer \
--vcpu 2 \
--memory 1024 \
--osinfo archlinux \
--disk /var/lib/libvirt/images/bastille-installer_qemu_archlinux-2023-04.qcow2 \
--import \
--boot uefi

I get to see this:

The FS0: in the mapping table is completely missing. And after exiting to see the boot manager I find that several boot options are missing as well.

These are the scripts that my packer config loads:

bastille-installer.pkr.hcl

...
  provisioner "shell" {
    only = ["qemu.archlinux"]
    execute_command = "{{ .Vars }} sudo -E -S bash '{{ .Path }}'"
    expect_disconnect = true
    scripts           = [
    "scripts/configure-qemu.sh",
    "scripts/configure-shared.sh",
    "scripts/partition-table-gpt.sh",
    "scripts/partition-ext4-efi.sh",
    "scripts/setup.sh"
    ]
  }
...

And this is the script that creates the bootloader.

partition-ext4-efi.sh

#!/usr/bin/env bash

. /tmp/files/vars.sh

NAME_SH=partition-ext4-efi.sh

# stop on errors
set -eu

echo ">>>> ${NAME_SH}: Writing Filesystem types.."
mkfs.ext4 -L BOHKS_BAZ ${ROOT_PARTITION}
mkfs.fat -F32 ${BOOT_PARTITION}

echo ">>>> ${NAME_SH}: Mounting partitions.."
/usr/bin/mount ${ROOT_PARTITION} ${ROOT_DIR}
/usr/bin/mkdir -p ${BOOT_DIR}
/usr/bin/mount ${BOOT_PARTITION} ${BOOT_DIR}

echo ">>>> ${NAME_SH}: Bootstrapping the base installation.."
/usr/bin/pacstrap ${ROOT_DIR} base `pacman -Qq linux`

echo ">>>> ${NAME_SH}: Updating pacman mirrors base installation.."
/usr/bin/arch-chroot ${ROOT_DIR} pacman -S --noconfirm reflector 

/usr/bin/arch-chroot ${ROOT_DIR} reflector --latest 5 --protocol https --sort rate --save /etc/pacman.d/mirrorlist
tee /etc/xdg/reflector/reflector.conf &>/dev/null <<EOF
--latest 5 
--protocol https
--sort rate
--save /etc/pacman.d/mirrorlist
EOF
/usr/bin/arch-chroot ${ROOT_DIR} systemctl enable reflector.timer

echo ">>>> ${NAME_SH}: Installing databases.."
/usr/bin/arch-chroot ${ROOT_DIR} pacman -Sy

echo ">>>> ${NAME_SH}: Installing basic packages.."
/usr/bin/arch-chroot ${ROOT_DIR} pacman -S --noconfirm sudo gptfdisk openssh grub efibootmgr dhcpcd netctl

echo ">>>> ${NAME_SH}: Generating the filesystem table.."
/usr/bin/genfstab -U ${ROOT_DIR} | tee -a "${ROOT_DIR}/etc/fstab" >/dev/null

echo ">>>> ${NAME_SH}: Installing grub.."
/usr/bin/arch-chroot ${ROOT_DIR} grub-install --target=x86_64-efi --efi-directory=${ESP_DIR} --bootloader-id=GRUB >/dev/null
/usr/bin/arch-chroot ${ROOT_DIR} grub-mkconfig -o /boot/grub/grub.cfg

echo ">>>> ${NAME_SH}: Show boot option.."
/usr/bin/arch-chroot ${ROOT_DIR} efibootmgr

echo ">>>> ${NAME_SH}: Generating the system configuration script.."
/usr/bin/install --mode=0755 /dev/null "${ROOT_DIR}${CONFIG_SCRIPT}"

In case it's relevant, this is how I create the partition table.

partition-table-gpt.sh

#!/usr/bin/env bash

. /tmp/files/vars.sh

# stop on errors
set -eu

NAME_SH=partition-table-gpt.sh

echo ">>>> ${NAME_SH}: Formatting disk.."
sed -e 's/\s*\([\+0-9a-zA-Z]*\).*/\1/' << EOF | gdisk ${DISK}
  o
  y
  n
  1

  +250M
  ef02
  n
  2
   
   
  8304
  p
  w
  y
  q
EOF

Relevant var files:

vars.sh

...
HOME_DIR=/home/${USER}
SSH_DIR=/home/${USER}/.ssh
ROOT_DIR='/mnt'
BOOT_DIR='/mnt/boot/efi'
FILES_DIR='/tmp/files'
ESP_DIR='/boot/efi'
...
BOOT_PARTITION="${DISK}1"
ROOT_PARTITION="${DISK}2"
...

I'm at a loss as to why I'm not getting my UEFI boot options
and why the filesystem is missing in the mapping table.

virt-install creates a completely new VM which does not know about the UEFI configuration of your existing VM.

The problem seems to be --boot uefi. You need

--boot loader=/.../OVMF_CODE.fd,loader.readonly=yes,loader.type=pflash,nvram.template=/.../OVMF_VARS.fd,loader_secure=no

instead (pointing to a copy of the other VM's file) in order to get the UEFI confguration.
