XCP comes in two flavours:

• The XCP applicance (which is a single, tested installable ISO image) that comprises CentOS 5.5, Xen and many other components

Is XCP a operating with Xen hypervisor?

Aka is XCP like a VMware ESXi or Oracle VM? It doesn't need to setup a operating system. Is that right?

A: Yes, the XCP ISO is a distribution based on CentOS 5.5 and is ready to provide easy handling by XE. Look at this link.

Can I install XCP to a USB drive / SD Card

Yes, but you'll have to repack the initrd with USB support. See this tutorial.

But be advised, at least XCP 1.6 has issues using an USB device (no matter if internal SD or external usb key), that causes the XCP Host to lose it's rootfs after 1-2 Days of runtime (obviously depending on the Workload). I tested 2 Brands of SD (Kingston and Samsung), as well as Kingston USB Key, same things. This has to be checked. (Hardware tested: HP Proliant DL360p Gen8)

Can I install XCP from USB drive / SD Card

Yes, but you'll have to prepare a Bootable USB Stick for this. A tool confirmed working for this is tool. Download the Program the rest is quite self-explanatory.
