I changed the obvious pebkac :-( of the identifier for the cdr, so I have

                ...
                disk = [ 'phy:/dev/VG0/tEFI,hda,w',
                         'phy:/dev/VG0/tBOOT,hdb,w',
                         'phy:/dev/VG0/tSWAP,hdc,w',
                         'phy:/dev/VG0/tROOT,hdd,w',
                         
'file:/home/test/archlinux-2016.02.01-dual.iso,hde:cdrom,r',]
                ...

Still, guest launch fails with

        xl create ./arch.cfg

                Parsing config from ./arch.cfg
                got a tsc mode string: "default"

Out of curiosity, I dropped

                ...
                disk = [ 'phy:/dev/VG0/tEFI,hda,w',
                         'phy:/dev/VG0/tBOOT,hdb,w',
                         'phy:/dev/VG0/tSWAP,hdc,w',
        -                'phy:/dev/VG0/tROOT,hdd,w',
                         
'file:/home/test/archlinux-2016.02.01-dual.iso,hde:cdrom,r',]
                ...

and on launch I get the same fail.
