Hi Ugo,

I've read some doc and there seems to be only the virsh command or the
Virtual Machine Manager available to manage xen on RHEL AP.

You can also use the Xen xm commandline tool directly.

Is is possible to use the Xen Administrator Console?

I think this is part of the proprietary XenSource / Citrix Xen product. It's not available in the open source codebase or, consequently, in RHEL...
I can confirm this. I'd like to see a webmin utility, but lack time and the Webmin module authoring experience to write one. Much like Nagios, there seem to be quite a few badly written bits of abandonware that show up if you go looking for open source tools for this: it's a lack of both Xen and VMware.

Since I don't install X on the host machine, it may be usefull, at least
at the beginning.

You don't need to run an X server on the machine in order to use virt-manager; if you have the relevant X libraries installed (which, depending on the RHEL packaging, might be possible without actually installing the X server) then you can ssh -X to that host from another system, then run virt-manager to have the app forwarded across the network to your local display. This is how I usually manage my RHEL machine.
Or run VNC, which also needs some X libraries and utilities. But compared to a fully equipped modern system, the small number of X utilities needed for this to work is quite small.

RedHat also has some expensive but powerful tools in their RHN utilities, which cost a pretty penny but are quite sweet for running such environments. I just wish they'd finish replacing Anaconda, their OS installer toolset, with something that actually works and can be configured properly.
Alternatively, you can (I think) run virt-manager on your local workstation and have it connect to the remote Xen machine. There is an example setup using SSH as a secure transport here: http://virt-manager.et.redhat.com/page/RemoteSSH and there are several other kinds of remote management setup linked from here: http://virt-manager.et.redhat.com/page/Main_Page

Hope that helps you,
