Hi, in the official XenNetworking ( http://wiki.xensource.com/xenwiki/XenNetworking ) i didn''t find reported how the NAT configuration works with xen. Does anybody know how the vifX.Y (10.X.X.128), gateway of any domU ethX (10.X.X.1) talk with the real ethX of the dom0? Thanks Enrico _________________________________...

..., I''m using a VLAN on each NIC and bridge the domU in it. But now I must create an additional domU which should be in an different VLAN. The best solution is to set a trunk on the switch and use 802.1q directly on the dom0. I found this site interesting. http://wiki.xensource.com/xenwiki/XenNetworking#head-4f6aecaa0342826a7259cd08948266093cca4365 The first method would do the trick but i wonder how to achieve that the Gentoo''s way. Any advices ? Thanks ! Ludo _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource...

Hello, I am experimenting with Snort and other IDS and I would like to use Xen for these tests. This would require me to use port mirroring to sent a bunch of packets to a NIC located on my Xen machine. I don''t really know how Xen networking works, but is it possible to give a domU direct access to a NIC ? Or at least give it enough access so that it can see packets that are not for the

...FF inet addr:192.168.122.1 Bcast:192.168.122.255 This seems to change everything with regard to networking. I googgled a bit and read the following links but I could not find any explanation about what it is, what it does and why it breaks my setup: http://wiki.xensource.com/xenwiki/XenNetworking http://www.cl.cam.ac.uk/research/srg/netos/xen/readmes/user/user.html#SECTION03220000000000000000 Can anyone point to an official information source for this beast?

Hello, I was following the steps on creating a new bridge and attaching a physical nic to it. ******Steps mentioned in http://wiki.xensource.com/xenwiki/XenNetworking#head-d5446face7e308f577e5aee1c72cf9d156903722 ***************** if you want to use multiple bridges, you must create them yourself, either manually, or via your own startup script, or via a custom script to replace network-bridge. For example: $ cd /etc/xen/scripts $ cp network-bridge network-cus...

Hi list, following my last mail I added a small jpg to clarify my request... How do I have to configure my dumm0 to enable communication between my firewall domU and my dom0. As mentioned I can ping/ssh from outside to domU (FW), I can ping ssh from there to domU(2.1) and domU(2.2). But I can''t get through to dom0. As most of the basic understanding is missing on my side even a

Hi. I have another question, hopefully easier than my last: Do all physical interfaces in dom0 need to have an IP addresse in order to be used as a bridge by guest domains? I thought that the interface would have to merely be "up" but not necessarily have an IP address configured since bridging is done at layer 2. But alas, if I don''t configure an IP address on dom0 the bridge

Hi, Ive built a new server using xen debian lenny packages. Im trying to firewall dom 0 which i can do ok but it then blocks access to the dom Us. Has anyone managed to do this successfully?

Have 4 xen servers with windows domains. 2 work OK and 2 have xp domains with slow network performance. Doing most of the testing on a xen system that currently is not in production. Running xen 4.0 with 2.6.32 kernel from lenny backports. Have xp service pack3 freshly installed with no updates. Installed gplpv gplpv_XP_0.11.0.213.msi hdtack gives 60mb/sec which is good iperf gives ~15Mbits/sec

Hi *, having built Xen 4.1.0 and running my Dom0 on Slackware 13.1, I''m trying to assign different physical network interfaces to different DomU guests: vif = [ ''bridge=ethX'' ] in the DomU configuration files. My /etc/xen/scripts/network-bridge script, however, doesn''t create more than one bridge: root@cen:~# /etc/xen/scripts/network-bridge start

...ow the interface that dom0 uses. It''s possible that I have remnants of my attempt to get Xen working from rpm''s on this system. I don''t know if that would screw anything up or not. Is there an up-to-date reference for how Xen networking is done? I''ve read the XenNetworking Wiki page through repeatedly and can''t glean the appropriate trouble-shooting information from it. In the VM I''ve tried configuring it for DHCP and giving it a static IP. Neither do anything. Should I just format the computer and start from scratch? I''m at my wit'...

Hi I would like to add some documentation to the xensource wiki. In particular I would like to add some notes on setting up firewalling on a Xen machine using a SuSE 9.3 dom0. (this is the Distribution I am familiar with) I can''t see an appropriate place linked off the front page to add this stuff. Also I can''t edit the front page itself to add a new catagory because it is

I''m using 3.0.2-3 and have gotten a matching user report from someone using 3.0.1. After powering off a VM, changing its MAC address and rebooting, it becomes unreachable. I made sure all ARP caches expired first before trying to contact the VM. Looking at the network traffic shows the ARP who-has query hanging indefinitely. "brctl showmacs xenbr0" also shows the old,

Hello all, so, while in my last experience with Xen I got many problems with network setup, I was looking for a network tutorial. I''ve already read http://wiki.xensource.com/xenwiki/XenNetworking . It''s a good background, btw I have to setup domU using a valid external IP. dom0 is: ip: 90.90.90.210 / 255.255.255.192 gw 90.90.90.193 domU (should be): 90.90.90.211 / 255.255.255.192 gw 90.90.90.193 In domU gateway should be external valid gateway or the dom0 ip?

...policy? I notice when domains are created it adds the extra rules to the FORWARD chain, to allow traffic to the guests. However, if iptables is restarted, all these rules are lost.
