will that also try to install the Xen Hypervisor as it being a dependent
of it, OR will it know that Xen 4.2 is already installed and running and
will only install the XenAPI Toolstack?

On the http://www.xen.org/products/cloudxen.html website, it just**says
*"In a nutshell, all you will need to do get the latest version of Xen,
the XenAPI toolstack and other components delivered in XCP is to execute
"apt-get install xapi"* But of course there is no *xapi* package in
debian, and either way it will try to install Xen as well when you don't
need it if you compile and install it first.

We wrote that page before we decided on a name for the package, so it's out of date.

xcp-xapi depends on the xen-hypervisor package directly. You can just let it install that package, and then probably use dpkg -r xen-hypervisor afterwards. If that tries to remove xcp-xapi too, then you could probably just delete the /boot/xen.gz file, and install it directly from source. I'm no Debian expert, so you might want to just ask this on one of the Debian IRC channels to be sure.


Hey mike, thanks for the reply, i really appreciate that. I have been wanting to install XAPI on a Debian Dom0 for a while now, but without random testing, i didn't know how to proceed, so i have not done much installing.

Originally i was looking at and following the Wiki Kronos page, http://wiki.xen.org/wiki/XCP_toolstack_on_a_Debian-based_distribution, but that is also out of date. As with all things, Project Kronos is still a work in progress i do understand that, and so far not too many guides out there to explain how to get it to work. So i was wondering about:

1.) Using the two commands found on the Project Kronos Wiki page, apt-get install xcp-xapi and apt-get install xcp-xe, the xcp-api package installs the Xen Hypervisor, Utils libraries, etc as a dependent, than what is the xcp-xe needed for?

2.) I currently have installed Debian Wheezy 64bit, compiled kernal 3.3.4 and running the latest Xen 4.2-Unstable, as of compiled a few days ago at least. SO, if i try to run apt-get install xcp-xapi, it will also download and install the xen-hypervisor-4.1-amd64 package, QEMU and many others. IF i let it, it will probably override my currently running Xen 4.2-Unstable WHICH i am guessing is probably not a good thing. SO i have not done so unless i know you can install JUST the XAPI Toolstack

3.) Has XAPI been converted to 64bit yet? I have read conflicting things where one places says the XAPI is currently only 32bit, but on one wiki pages it shows as 32bit or 64 bit. So figured i ask since i am using a 64bit Debian Wheezy and don't believe a 32bit XAPI could run on it.

4.) So, there is no way to download JUST the XAPI toolstack source, compile it and install? Looking in the xapi-autobuilder.git, it says the same thing that the XAPI is compiled with all dependencies, including Xen Hypervisor.

5.) Finally, is the latest version of XAPI compatible and can be run on Xen 4.2-Unstable?

Thanks again for the advice...
