I've successfully installed XCP on a SD card some time ago, but I
don't recommend that. Running an OS from a SD is not recommended
because the access time is large, and the system can feel
irresponsible some times.

Installing the image and doing a dd will not work straight away, you
will have to use syslinux to make the usb bootable, but again you will
face access problems.

I'm using a SD card to boot a regular Xen install (4.1.2) on some of
my servers, using Alpine Linux which is easy to install to a SD card,
has a very small footprint and works great with Xen. Don't have
experience with XenServer.
