Hello A simple question Is virtualization (Xen) in CentOS stable for big developments ? Somebody is using it for important servers ? Would have to wait for an update?

I currently do manual updates of Xen-related stuff, since there still is a bug that affects us (#1999). I think there were some other problems with the network scripts as well. But as far as I recall these problems will be fixed in 5.1. Some machines also have problems with more than one vcpus in a domU (see the recent discussion on the centos-virt list). 5.1 will have some useful improvements over 5.0 (e.g. support for running i386 domUs with a x86_64 hypervisor/dom0). -- Daniel

As mentioned before, there are still some unresolved bugs. Recently I did standard virt-install deployment using files as a storage, and performance is terrible (even for not very busy servers). If you need to use it, I would recommend not to use virt-install, and use separate lvolumes as storage backend. I also have impression that networking performance is degraded in comparison to vanilla Xen deployments.> Would have to wait for an update?With my recent experiences I would wait for update or use vanilla Xen.
