DevCloud with Centos and Xen

Does anyone know if Centos 4.2 running Xen (not xenserver) hypervisor work
with CloudStack 4.2?

I am trying to build a DevCloud on Centos. I have Xen running but when I
try to add the host to cloudstack I get "unable to add host" - the log
shows:

Re: DevCloud with Centos and Xen

Posted by CK <cl...@gmail.com>.
For my host, I have Xen(XCP) running on Centos6.4, is there a plugin or
something that I also need to setup/configure on this host for it to be
recoginised by CloudStack 4.2?

At the moment when I try to Add Host it does not find it, what does
cloudstack look for on the host to identify it is a Xen host?

I have no real idea of how the LXC implementation works, but it's layered on top of libvirt and it's KVM/QEMU drivers. Would tapping into libvirt in the same way with it's Xen driver be possible?

And I ask that having zero idea of how CS uses QEMU and libvirt to get its hooks into KVM or KVM itself or LXC.

In a few words; not easily.
CloudStack talks to the XenAPI - which CentOS doesn't have by default.
There was some work to build XAPI on EL6 with the CentOS + Xen work
that was happening, but I don't know where that stands. If you did get
XAPI on CentOS, you'd still likely need to fake the version
information.
