OK, What's the best CentOS platform for KVM? CentOS 5 or CentOS 6?
TIA, Gene It's impossible for everything to be true at the same time.

At this time you should only install CentOS 5 when you absolutely have to for compatibility reasons. For new Installations you should always use CentOS 6.

As Dennis said, use CentOS 6 unless you must absolutely use 5. Newer packages and it will have a longer support life cycle from today until it is EOLed.
Since CentOS follows Upstream's cycle closely here are dates. https://access.redhat.com/support/policy/updates/errata/

While I agree that CentOS6 is the new and better OS I should say that it has several serious problems (bugs) that have been bugging us for several months to the point the we began considering going backwards to 5 which was solid as rock from day 1. Apparently these bugs (related to the kernel and possibly nfs4) have been fixed in RH EL6 but only to those that maintain a service contract.

Are there by chance bugzilla entries for those? Just out of curiosity - NFSV4 is an area of interest to us, in the future.

Yes, there are. I have been following them closely (and patiently) but you will have to wait until tomorrow for their bugzilla id's.

Have you checked the newest kernel from the last few days? It has a few nfs fixes included:

I see NFS4 geeting used more and more, but still many production sites staying on NFSv3.
