I installed Xen pkgs rebuilt with

  --with-ovmf \

Checking at the build log,

  [   70s] + ./configure --with-ovmf --disable-xen 

I enabled verbose logging @ Dom0 grub

  GRUB_CMDLINE_XEN="... debug loglvl=debug guest_loglvl=debug"

I passed through & formatted an ESP for my Xen guest.

I installed Arch guest, and setup systemd-boot

 bootctl --path=/boot/efi install

 cat /boot/efi/loader/loader.conf
  default  arch
  timeout  4
  editor   0

 cat /boot/efi/loader/entries/arch.conf
  title          Arch
  linux          /vmlinuz-linux
  initrd         /initramfs-linux.img
  options        root=LABEL=ROOT resume=LABEL=SWAP rw

 bootctl --path=/boot/efi update
 tree /boot/efi
        /boot/efi
        |-- EFI
        |   |-- Boot
        |   |   `-- BOOTX64.EFI
        |   `-- systemd
        |       `-- systemd-bootx64.efi
        `-- loader
            |-- entries
            |   `-- arch.conf
            `-- loader.conf

I added 

        bios='ovmf'

to the .cfg, and launched the client

 xl create -c ./arch.cfg
        Parsing config from ./arch.cfg
        got a tsc mode string: "default"
        xenconsole: Could not open tty `/dev/pts/4': No such file or directory
        xenconsole: Could not read tty from store: No such file or directory
        libxl: error: libxl_exec.c:118:libxl_report_child_exitstatus: console 
child [4683] exited with error status 2

and at the Dom0's serial console, I get only
