Everything is a Freaking DNS problem

We need more tips about drupal and how to optimalize it.

Thanks for the post. It's nice to read some articles on Xen. I think it's a great hyper-visor that gets overlooked more times than not. Xen is a great thing when it comes to virtualizing those old little Netware boxes you can't seem to get rid of, and it's a viable solution for lots of Novell applications in your enterprise from a Groupwise Mobile server to even eDirectory, and even iPrint servers. Novell needs to improve on their management side of virtualization to truly compete with other hyper-visors on a wide scale.

KVM does give you significant benefits.

Xen is great and we're used it here (550+ employee, aviation-related R&D and systems engineering firm) with great success, particularly for para-virtualized Linux VMs.

But honestly, it's not about the hypervisor, it's about how the hypervisor is implemented. KVM, being a pair of kernel modules, means that any system running RHEL is a potential virt node. Just probe modules, and migrate. This is a much more flexible model than having to reboot into a Xen-modified kernel.

KVM will, in the long run, greatly benefit from taking advantage of advancements in the kernel, without developers having to re-invent them, as is the case with Xen.

Paravirt was the compelling feature of the Xen platform, but with hardware-assisted virt evolving, we think it'll be less of a factor in the future.

The KVM-based Red Hat Enterprise Virtualization platform we're currently beta-testing has accelerated network drivers; we're typically i/o-bound, so one of our main concerns is dealt with.

I'll stick with Xen.

A few weeks ago I assisted to RedHat Tech event here in Santiago of Chile, and there was a presentation about virtualization. Obviously, the guy talked about the inclusion of KVM with RH and said that we (admins, users) will have the opportunity to choose with technology use. But, after listening him talk about KVM, I'll keep Xen on my Red Hat (and RH based) servers and obviously in my Debian ones!

Although I can see the advantage to KVM to a certain degree however it is not a real Hypervisor. Using platforms with embedded HV's are really the way to go.

NO... Stick with Xen!

Whether they are RHEL customers following suit or others is a good question.

I don't known who is voting for "Yes, I will follow RedHat to KVM" but I don't

Are they try to play like the proprietary company's
or would they use the open source way in the future

I hope they will think about that! and take a good decision

Why would anyone migrate to techX or techY because redhat does so? Except if you are a redhat/centos use, you shouldn't move *because* RH moves...
