Hi all.
I am currently building a small test cloud based on Eucalyptus 2.0.3 and CentOS 5.8 x64. I have a choice which hypervisor to use: KVM or XEN. KVM is the default in CentOS 6 but I have read also many good things (for example PV guest machines, isolation between Dom0 and DomU) about XEN.
Key factors from my opint of view are: - stability (which one runs more smoothly on CentOS?) - performance (XEN PV/HVM(with or without pv drivers) vs KVM HVM(with or without pv drivers)) - security
Could you share your experience in these areas?
Best regards, Rafal Radecki.

there are people who will argue both ways - and even add other options to the mix and swear by them. End of the day, its going to be a case of you having to put in a bit of time and eval the options based on your own constraints and take it from there.
I use Xen quite a bit, I also use KVM - almost as much as Xen. And I find they both solve their own problems in their own ways. I also use VirtualBox and staring to get lxc into the mix. I have used vmware products in the past.
