Re: [FreeBSD 8.2 amd64 XENHVM] DomU terrible network performance trought NAT
I think you should try totally disable the window sizing both parts to isolate it doesn't come from here : On your FreeBSD VM : sysctl net.inet.tcp.rfc1323=0 On your Linux box : sysctl net.ipv4.tcp_window_scaling=0 Then if the rate is hugely better, try some settings to increase the compatibility. You can also try an *iperf *test with TCP and UDP packets to see if the behavior is generalized, and see what latency you have both part of the network.

Re: [FreeBSD 8.2 amd64 XENHVM] DomU terrible network performance trought NAT
Maybe you should have a look on the tcp window size values. I had such a behavior with two gateways who was not playing the same way with the TCP window size which made my network damn slow. If you have a linux gateway in front of your FreeBSD VM, it should be this. Command Description sysctl net.inet.tcp.rfc1323=1 Activate window scaling and timestamp options according to RFC 1323.sysctl ipc.maxsockbuf=*[sbmax]* Set maximum size of TCP window.sysctl net.inet.tcp.recvspace=*[wstd]* Set default size of TCP receive window.sysctl net.inet.tcp.sendspace=*[wstd]* Set default size of TCP transmit window.sysctl kern.ipc.nmbclusters View maximum number of mbuf clusters. Used for storage of data packets to/from the network interface. Can only be set att boot time - see above. sysctl net.inet.tcp.liondmask=7Used to enable the "netlion" patch above.

I did try with Xen 4.0.0. But more stable doesn't meens "suitable for production use" ... I think the FreeBSD team has to work on its kernel to make it stable under paravirtualized environment.

For i386 (small instances) EC2 either needs to update to a non-antique version of Xen or support for not using linear pagetables needs to be restored to xen/pmap.c. For amd64 (medium and large instances) a new xen/pmap.c would need to be written. This isn't a great deal of work, but most users seem to be having a great deal of success with just running HVM with PV drivers.

RE: FreeBSD on Amazon EC2
I agree but I think the major problem is that all the Linux distributions are abandoning Xen because of its difficulty to maintain. (I fear especially for Debian which is the main interesting distrib for Xen dom0) For now the only OS who is maintaining Xen as Dom0 is NetBSD and its not so great by my humble opinion. So maybe it would be a good thing to look at alternatives to Xen or patiently wait for Xen 4.0 :( Cordialement, Guillaume Seigneuret logo_625x333 Network and System Security Architect Web : <http://www.omegacube.fr> http://www.omegacube.fr Address : Hôtel Technologique - BP 100 Technopôle de Château Gombert 13382 Marseille Cedex 13 De : Zladivliba Voskuy [mailto:nospam...@hotmail.fr] Envoyé : lundi 3 mai 2010 19:54 À : g...@omegacube.fr Cc : freebsd-xen@freebsd.org Objet : RE: FreeBSD on Amazon EC2 Thanks for your interesting view on the subject.

RE: FreeBSD on Amazon EC2
Dear Zlabivliba, I think it's going to take a while for FreeBSD to perfectly work as a paravirtualized DomU. SMP doesn't work, there is no AMD64 kernel available, and the stability has to be improved under heavy load. I guess the first work will be done on the stability of the virtualized OS and then some new feature will appear. Maybe a FreeBSD developer could tell us about this but I also guess this is not a priority since they added FreeBSD jails.

RE: FreeBSD on Amazon EC2
For the moment FreeBSD is not stable as a paravirtualized DomU. I test it for a while and it crashes under heavy load. If you need to test it, I'm sure it'll work on Amazon EC2 patform but don't expect have it as a stable production environment.

I'm trying to find a solution to run FreeBSD on the Amazon EC2 platform. Anyone succeded at building an image that could actually run ? There's a lot of interest out there about this subject and my guess is that FreeBSD would make a great choice for cloud computing. I'd really like to see it working soon.
