Hi,
just two questions:
Is there anything faster than XEN-paravirtualization?
Why XEN 5?
XEN 3 is quite stable, too.
I guess you mean Citrix XenServer 5.5 with "Xen 5" ?
It's a completely different, full commercially supported product from Citrix, which has the opensource Xen hypervisor as a part of it. Actually it's based on CentOS.
Citrix XenServer 5.x uses Xen 3.x hypervisor.
I have 31 DomUs up and running on a single Box - and have a strong feeling that even 60 will run flawless. But: All of them are Para-Virtualized.
Yeah, Linux PV guests perform and work OK.

I have no problem with disk IO-Bottlenecks since my DomUs are not Database-Servers - so there is mostly static information in the filesystems.
I see no reason why I should move to KVM. My only limitation is memory, since RAM is not being virtually mapped yet.
Kind regards
Nils
