Hm.  that's good to hear.   I plan on setting up a Eucalyptus cluster myself
soon

Eh, personally I have been using CentOS/RHEL for a while (mostly because
that's what my consulting clients want, so I might as well get experience
that is relivant.)  

Recently, though, I've moved prgmr.com to the Xen.org kernels, because
xen.org 3.3 is compellingly better, as far as I can tell, than the backported
RHEL  5.2  Xen 3.1/3.0.3 mess.  

I've stuck with a CentOS userland, as the xen.org kernel is 2.6.18, just
like the CentOS 5 kernel, so it mostly works as a drop-in replacement.  
Last time I did this with a distro that was expecting a more modern 
kernel, I had to replace all sorts of utilities... from vmstat on up.  

I do think that the 3.3 hypervisor is compellingly better than the 3.1/3.0.3 
hypervisor that CentOS/RHEL and ec2 use, and it's backwards compatable, so
I don't see the point of hobbling yourself just 'cause amazon has done so.
