I've been using FreeBSD on Citrix Xenserver with FreeBSD 8.[012] for a year now; in HVM mode. The only issue, other than the lack of support for xentools, is that in the earlier 8.x I had to manually set kern.hz low or the clock would eat too much CPU time in the VM (IIR, this was fixed in 8.2). I haven't had an opportunity to try FreeBSD as a PVM. -- Perfection is just a word I use occasionally with mustard. --Atom Powers-- Director of IT DigiPen Institute of Technology +1 (425) 895-4443 From owner-freebsd-xen@FreeBSD.ORG Wed Sep 21 00:20:10 2011 Return-Path: Delivered-To: freebsd-xen@hub.freebsd.org Received: from mx1.freebsd.org (mx1.freebsd.org [IPv6:2001:4f8:fff6::34]) by hub.freebsd.org (Postfix) with ESMTP id 9C23B1065670 for ; Wed, 21 Sep 2011 00:20:10 +0000 (UTC) (envelope-from gnats@FreeBSD.org) Received: from freefall.freebsd.org (freefall.freebsd.org [IPv6:2001:4f8:fff6::28]) by mx1.freebsd.org (Postfix) with ESMTP id 8C1578FC18 for ; Wed, 21 Sep 2011 00:20:10 +0000 (UTC) Received: from freefall.freebsd.org (localhost [127.0.0.1]) by freefall.freebsd.org (8.14.4/8.14.4) with ESMTP id p8L0KAe1070846 for ; Wed, 21 Sep 2011 00:20:10 GMT (envelope-from gnats@freefall.freebsd.org) Received: (from gnats@localhost) by freefall.freebsd.org (8.14.4/8.14.4/Submit) id p8L0KAF4070845; Wed, 21 Sep 2011 00:20:10 GMT (envelope-from gnats) Date: Wed, 21 Sep 2011 00:20:10 GMT Message-Id: <201109210020.p8L0KAF4070845@freefall.freebsd.org> To: freebsd-xen@FreeBSD.org From: dfilter@FreeBSD.ORG (dfilter service) Cc: Subject: Re: kern/154302: commit references a PR X-BeenThere: freebsd-xen@freebsd.org X-Mailman-Version: 2.1.5 Precedence: list Reply-To: dfilter service List-Id: Discussion of the freebsd port to xen - implementation and usage List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , X-List-Received-Date: Wed, 21 Sep 2011 00:20:10 -0000 The following reply was made to PR kern/154302; it has been noted by GNATS.

At first I was willing to have only FreeBSD VMs, but I had a strange problem when NAT was enabled on the front FreeBSD Vm that had the public IP address. Network bandwidth from backend FreeBSD VMs to Internet and from Internet to backend VMs was incredibly slow, tested with NAT feature of PF and with natd, same problem, also with GENERIC kernel. Bandwidth between all VMs was correct, only when passing the NATed public interface caused problem. That's why I put a Linux box for NAT, which is working perfectly now. So far it was the only problem I had with FreeBSD and Xen Cloud Platform. My FreeBSD VMs are serving nginx + rails and python apps, PostgreSQL and MySQL databases, and the perf is good for now. VMs disks are LVM partitions of XenCloud, not files. > > Thank you very much. > Good bye!. > Hope this helps.

It would have been nice if you had tested (for the test only), one physichal machine with FreeBSD doing nat and the other three vm under Xen with FreeBSD, to see if problem persists...this way we could figure now if the problem was something to do with Xen or with the own FreeBSD configuration... although I assume the problem is in the last one... > So far it was the only problem I had with FreeBSD and Xen Cloud Platform. > > My FreeBSD VMs are serving nginx + rails and python apps, PostgreSQL and > MySQL databases, and the perf is good for now.
