Hello. I recently tried installing NetBSD-5 on xen-4.0.1-rc5, which resulted in no network (xennet0 can''t get IPs per dhclient and has no connectivity if set by hand). Tried it with netBSD-5.1-RC3-1 i386 PAE & amd64, netBSD-5.0 and even 4, all with the same result. On a older xen version (3.3.1) networking works fine, so I assume it''s a xen bug, and not a netBSD-kernel

Hi, we have a software accessing a lot of small files. We installed Xen 3.2 on a server with two quad core Xeons. We installed two domains with our software on Linux and put it into production.
