Xen users - Oct 2010 - XCP, technology question

Hey folks!
    I was just reading an article today that claims ''VMware still has
at
least a "five-year, pure-technology lead on both Xen Server and
Hyper-V."''

I''m not a VMware expert myself, so I thought I''d throw the
question out.
Considering Xen Cloud Platform since it''s leading XenServer, and 
figuring the various management and operations packages rolling for XCP, 
just exactly what, capability wise, is XCP missing in comparison to VMware?

Some of the VMware tools are nice, but I don''t think it is accurate for
somebody to say VMware has a 5 year lead on Xen or Hyper-V at the
virtualization level.  

The advantages that most VMware fanboys tout are things like hybrid clouds
and RAM overcommitting.  Those are features that I personally have no
interest in.  RAM overcommitting us the surest way to get poor performance.
Instead of buying VMware licenses, I argue that the money is better spent on
buying more RAM.

If the Xen crowd wants to close the gap on VMware, it will need to be done
through the tools.  For example, a build of XenCenter should be released
that works with XCP.  XCP is terrific for us who write our own cloud
management applications, but everybody else really needs really user
friendly tools to work with.  

A lot of people are interested in XCP but refuse to use it because XenCenter
does not work with it.  Not releasing a build of XenCenter that works with
XCP is merely disadvantaging the XCP community and encouraging people to
look at VMware and KVM.

One technology I hear is limiting IOPS for guest depends on access time
to storage. If access time starts to raise (means storage near they
throughput limit) VMWare limits number of IOPS for most disk-using VMs.

I don''t check this at works, but it sounds cool and I know XCP,
Xen+xend
or XenServer lacks of this feature.
