Hi, I was hoping someone on this forums could help me out with a problem I was facing with Xen. When I compiled the kernel for Xen-3.1.3 using "make world"(I know this is an old version but I need to use it for some compatibility issues), the kernel was missing the Xen netloop module. There was no /kernel/drivers/xen/netback/netloop.ko in the newly compiled kernel. I think we would

Hi, this is propably bridge related and not really a xen problem, but it might help someone: Some of our domUs are not able to arp. Arp -n show (incomplete), and doing a tcpdump shows, that on the dom0''s eth0 the arp request goes out, the response comes in, but on the vifX.0 interface the arp response is gone. dom0# tcpdump -ni eth0 arp who-has 10.32.2.51 tell 10.32.7.70 arp reply

Hi, I have a strange problem with my networking setup. I read all forums around the world where people had similar problems, but couldn''t find a solution. I have an Attansic L1 gigeth chip on my mainboard. This chip works OK in stock Ubuntu Gutsy (development) 2.6.22-9-generic kernel. When I boot into Xen, and after the bridge is created, the network stops working. Some info: - If I

Hello, I''m used to using Xen in a bridge mode where my dom0 and all domUs are on the same layer 2 network. However now I have to set up a server whose eth0 is on one network and the domUs will be on another /29. So, for example, if the eth0 of dom0 is 192.168.1.214/24, then I have 10.1.1.0/29 (10.1.1.0 -> 10.1.1.7) routed to it for use in domUs, how would I go about setting that up?

Hello again, folks! I''m getting one strange problem with FC5 running on XEN 3.0.3 x64... The MRTG point to my machine with XEN running one absurd volume of output data sent (normal is around 6 MB/s) and when XEN is working we get 80 MB/s until my DRAC is alive... after this, the machine crash, DRAC stop do reply, swith stop do work together... Anyone knows whats happening now? ;)

I tried netperf / netserver with Dom0 / DomU, but I could''nt get a correct NW traffic with xentop. Is there anybody could help me?

Hello you all out there Does anybody know the definite guide to create a dummy ethernet device? So, what I want to have is an ethernet device, without a physical link, or so called a dummy device. My goal is to have apache with mod_proxy and balancer running on peth0 in dom0. Apache is spreading my connection to the backend domU''s, where the webservices are running. The connection

Hi !

Hi, I try to get networking running with xen 3.2, but it seems I fail miserably. I am on sles10sp1, with xen 3.2.0, and kernel rpm''s installed from SP2.

Hi I have an Asus M2N32 WS Pro, 4G Ram, AthlonX264 4600+. I Installed SuSE 10.3 (64bit) on Dom0, LVM on Raid 5. All domU''s boot off LVM, using same Suse 10.3. I have a firewall (fw) domU running shorewall and a domU name-dhcp-server (nds). Somewhere in between 10 and 16 hours the network stalls. In dns, I can see dhcp queries and offers, but these never make it to the clients in the

At OLS I gave a talk on some of the Xen scalability inhibitors, and one of these was writable page tables. We went over why the feature does not scale, but just as important, we found that the uniprocessor case does not provide any advantage either. These tests were done on x86_64, so I wanted to run the 1-way test on 32 bit to show the same problem. So, I have run with writable PTs and

Hi there, I'm currently experiencing a minor problem using the bridge module under kernel 2.4.27 part of the Devil Linux distribution (http://www.devil-linux.org). The problem I am having is that when the bridge is unloaded during a reboot I receive the following errors in /var/log/messages: Nov 14 13:22:13 src@Devil kernel: unregister_netdevice: waiting for br0 to become free. Usage count =

When i want to delete my test bridge, using: ifconfig eth0 down ifconfig eth1 down ifconfig br0 down brctl delif br0 eth0 brctl delif br0 eth1 brctl delbr br0 i get this error message from the kernel on the console: unregister_netdevice: waiting for br0 to become free. Usage count =3D 2 The brctl user-level command is blocked. Could you explain me what could likely be the cause of this error?
