It does not matter whether you have xen kernel or simple on DomU. If it is DomU then you have /proc/xen/

On many modern distributions the xen0 and xenU kernels are exactly the same, so a dom0 and a domU will display similar uname information. However, as you say, there are other ways to tell, like device names (although, those can be set to almost anything you like), dmesg output, proc info, etc.

A "uname -a" indicates that your are running a xen domU, if it is a PV
domU. A "ls /boot" would indicate the same. Of course you could change
the name of the kernel. In a HVM domU probably you do not need since you
are using a kernel without modifications
A "more /etc/fstab" can also indicate that the devices being used are
xenified (depends on your configuration). I for example, use /dev/xvda1
as my partition, to not forget that its a Xen box ;-)
Probably there are other ways to check it ...
