    -xen-attach is needed for pvh boot with qemu-xen
    
    Currently the boot of a pvh guest using the qemu-xen device model fails
    with the error
    xen emulation not implemented (yet)
    in the qemu-dm log file. This patch adds the missing -xen-attach
    argument.
    
    V2: Use  b_info->type != LIBXL_DOMAIN_TYPE_HVM    instead of
            (b_info->type == LIBXL_DOMAIN_TYPE_PV) ||
            (b_info->type == LIBXL_DOMAIN_TYPE_PVH)
    as recommended by Roger Pau Monné.
