Hi, i have succesfully configured Xen 3.0.4 with 2.6.16 kernel on some C2D hw with currently 2GB RAM. Only hitch was with the integrated Intel Gigabit network card which is not supported by by default xen kernel - so there is e1000 module compiled from intel sources. Server is connected on 100Mbit ethernet line. Network setting is currently bridged. At the moment 4 domUs with various linux PV distributions - Debian,Centos,Gentoo. None of running servers are under load. What am I seeing is interrupts in continuous ping and that ssh console connection is laggy. When rebooted to non-xen kernel - without any issues. Please can anybody point me where should I look for possible cause of above descripted problems? Another question is - when configuring xen kernel form dom0 - which kernel Hz setting shall I set? 250 or 1000? And according to this question - should be this setting same also form domU kernels?

Hi, I see that same hale the same problem with e1000 so I think that we have some similar machines. As the dom0 I use gentto 2007 distribution while it have XEN 3.0.4 from default. My compilation use is 250 Hz for kernel. I don''t have any reason why it should be this value I found it on the gentoo forum: http://forums.gentoo.org/viewtopic-t-551077-highlight-xen.html Best -- ASEC S.A.

Hi, thanks for the response. Is anybody here seeing same problems with e1000 and 2.6.16 kernel?

Hi, I had the problem with these network card. I use gentoo 2007. I adopt driver from 2.6.17 kernel witch work in native kernel and its now works in 2.6.16. I could post you the files maybe they will work for you. I also found that somebody (I don''t have the strict URL) compile the module form driver sources that are available on the Intel site. -- ASEC S.A.

Bartolomiej, so now do you use Intel gigabit card without issues? At the moment am using e1000 as module compiled from latest intel sources. Am thinking about replacing the card with classic PCI 3Com 905c to avoid issues. Anyway am running on 100Mbit. Maybe is the problem that my Intel e1000 card is inthegrated on i965 chipset based mobo which could be problematic to use with 2.6.16 kernel but am having no issues with this mobo only with network - ping timeouts, laggy ssh. Any suggestion? Peter 2007/5/15, bdubas@asec.com.pl <bdubas@asec.com.pl>:> Hi, > > I had the problem with these network card. I use gentoo 2007.

SOLVED! The problem was that lag and ping interrupts was affecting only 2 domUs. After some investigation we have found the we defined for those domUs same MACs. With different MACs no problem at all.
