Hi all! I have a question: what is the overhead of xen? I mean, I'm going to install xen on servers with VT compatibile cpus (xeon) , raid5 disks and much ram. I will use logical volume to manage storage. what is the loss of cpu / disks /memory due to xen? For example now, without xen, servers are not much used but some days of the month I have to execute perfomance tests ( resourses used almost at 100%) After installing xen, I will have to do the same: I will stop every domains except for Dom0 and Dom1. So what loss of performance should I expect? Thanks Marco Strullato _______________________________________________ Xen-users mailing list Xen-users@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-users |
