Hey guys,

It looks like I was able to get CS to recognize my iSCSI storage last night
after setting it up ahead of time in XenServer.

I would like to do the same thing with DevCloud2 (which, it sounds like,
uses Xen + XAPI).

I used XenCenter to configure my XenServer, but I'm having trouble with Xen
(as in, having trouble with DevCloud2's Xen).

Does anyone know (I'm pretty new to Xen and XenServer) if I should expect
XenCenter to work with Xen?  I don't see any process listening on port 80
in my Xen VM, so that is a bit unexpected (since port 80 is what I used to
talk from XenCenter to XenServer).

Also, I wanted to test kicking off a VM instance from CS on the iSCSI
storage that I do have working.  When I walk through the wizard, I don't
see any ISOs or templates to choose from.  I assume those should be stored
on Secondary Storage?  Is there a way for me to populate that with default
data so I can make my way through the wizard?  Also, if I want to provide
an ISO to choose from, can someone point me to instructions on how to make
that work?

Thanks again everyone for the help!!
