XenServer is Xen + CentOS Dom0 + XAPI + installer + some extra tools.

So Xen or community XenServer? Is there a difference?
Yes. One is a kernel, one is a distro.
Xen is just the hypervisor a la Linux. XenServer is the official distro made by Citrix and Xen themselves that has everything that you need to actually use Xen a la CentOS.
So Xen is to Linux as XenServer is to CentOS.
Ah, this makes sense I was trying to articulate this in my head and couldn't. Thanks for the clarification.

So what is it about XenServer that makes it preferred over KVM particularly for Linux workloads?

Performance. KVM works hard to make Windows fast. Xen works hard to make Linux fast.

Great, thanks for all the input. I appreciate it.

Just so I'm clear on the XenServer stuff... XenCenter (the management tool that is equivalent to VMware's vSphere) has also been open sourced, right?

I don't think so. It is included in the XenServer package but wasn't one of the tools that was open sourced.

According to http://xenserver.org/partners/developing-products-for-xenserver/21-xencenter-development/88-xc-dev-home.html it appears to be.

No, it is free but not open source.

Citrix does not own it to open it.

Oh, that's news good to know.

Oh neat, that is new. Maybe they finally got everything cleared to open it.

Maybe now we will see a decent *nix version of it. Although the CLI commands are pretty easy to use.

@coliver would be awesome. Someone needs to get on that. Although the XAPI has been there for a long time and no one has made the interface that we want yet.
Really running on Linux is pointless, what is needed is a web interface. Anything else is just silly.

Xen Orchestra is around but they have a silly limitation on the number of hosts it can manage.

Yeah, it's limited nearly to pointless.
