similar to: dealing with "eth0: received packet with own address as source address"

This patch adds an ACM hook into the network scripts (/etc/xen/scripts). It adds iptables rules that enforce mandatory access control on network packets exchanged between virtual interfaces. If ACM is active, this patch sets the default FORWARD policy in Dom0 to DROP and adds iptables ACCEPT rules between vifs that belong to domains that are permitted to share (determined by using the

Hi, I would like to know if somebody can point me out how to configure several DomUs in a private LAN (for example 192.168.100.0/24) and one DomU with two interfaces (one - 192.168.100.0/24 and two - internet). So far I have enabled in xend-config.sxp: (network-script network-route) (vif-script vif-route) My config files have: /mnt/VM/1.cfg:vif = [''ip=192.168.1.3'']

Hi, we''re running 4 xen servers on our network with multiple network cards. During HighLoad we experince degeneration of inbound network traffic through our loadbalancer. I might found a reason for it, in Dom0 dmesg output looks as follows: [1157421.975910] eth0: received packet with own address as source address [1157421.975957] eth0: received packet with own address as source

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

Package: xcp-xapi Version: 1.3.2-14 Severity: important I chose the Open vSwitch (ovs) networking mode when I installed XCP # cat /etc/xcp/network.conf openvswitch Whenever I boot a VM, I notice that the vif interface is created (e.g. vif1.0) on dom0, and the vif is added to the ovs bridge (I can see it in the output of ovs-vsctl show) However, there is no connectivity, I can't ping the

Hi folks, I read quite some posts about "Destination host unreachable" problems before, but none could help me to solve my issue. So here we go: This is what I am using: SUSE Linux Enterprise Desktop 10 SP1 - Current with all updates Network configuration of my dom0: foobar:~ # ip a 1: lo: <LOOPBACK,UP> mtu 16436 qdisc noqueue link/loopback 00:00:00:00:00:00 brd

My domains dont see any traffic until you try to connect out from within the domain. Tried this several times and it was consistent. I have no firewall either. running each domain on different cpu probably doesn''t help, although Im no network expert. Here is some info. ================ [root@a root]# xm info system : Linux host : a.b.com release

Here is the situation. I have a xen system with 2 drives setup in a RAID1. I pulled one drive and put it into an identical server. Now, when I boot up the new server, peth1 is not created. [root@dom0 ~]# ifconfig | grep Link eth1 Link encap:Ethernet HWaddr 00:14:38:A7:55:C2 inet6 addr: fe80::214:38ff:fea7:55c2/64 Scope:Link lo Link encap:Local Loopback vif1.0 Link

Pardon me for a long detailed post but this looks pretty serious. The bottom line is that, when I attempt to shut down or reboot my simple xen-2.0.7 server running FC3 with two domUs, shutting down xendomains appears to send python into an infinite loop. This may be due to a serious misconfiguration on my part but it is certainly a big problem. If we shutdown the domUs manually first, the

Yes, I saw that problem and removing the vif line or changing it to vif0 fixed it for me.

Hello, I am having big problems with Xen virtual network interfaces. First I tried typical bridge support, no luck. The packets sent from dom0 to domU seemed to disappear somewhere. Then, to debug the problem I have set up a simple point-to-point link and still have the same problem. I am using Xen 3.0.4-1 and Linux 2.6.16.x in both dom0 and domU. I have tried kernel 2.6.16.35 and 2.6.16.41. I

Hi list, i''ve been migrating our RAID1 system onto bigger drives. Therefor I''ve setup a new dom0 with a 2.6.32-5-xen-amd64 kernel and Xen in version 4.0, because there was a 2.6.19 kernel and xen 3.0.1 causing problems time by time. My main problem is, that the domU running our intranet services (webserver, mail, databases etc) is not responding or rejecting each attempt to

Hello everybody, I have an odd problem with iptables using a Xen bridge setup. I don''t know if it would be better to post to netfilter Mailing-List. But I hope someone here know how to solve it. If it''s OT here, please let me know. I''ll try to do a little bit ASCII-Graphics to explain the topo better: _________ ________

Hello everyone! I''m new with Xen and i''ve been dealing with the same error the last week. I''m pretty much lost, i don''t know what else to do so i ask for your help. In my case i installed Xen on a amd64 Pc, with Gentoo. I installed the following packages: xen, xen-tools and xen-sources from the gentoo repositories. I''m using 2.6.31-xen-r10 gentoo

Hi, I''ve bit the bullet and gone with Xen, but I get some odd networking. Basically, this was the original idea. eth0 external eth1 internal create bridge br0 for eth0 create bridge br1 for eth1 Strip IP addresses for eth0 and eth1 and assign to br0 and br1 respectively. Worked great in a non-xen kernel under Fedora 8 in KVM/Qemu. Booting into Xen, my eth1 becomes eth2, I also get

Hi, I thought I'd query this here before opening a bug I installed XCP wheezy and imported a couple of my domU instances I chose to use Open vSwitch (ovs) networking mode I notice that each vif is created (e.g. vif1.0, vif2.0) when the domU boots. However, they are not bridged. As a hack, I just do brctl addif xenbr0 vif1.0 and then my domU is reachable. But I realise I should not

Hello, The basic details of my host and XEN configuration and network configuration all appear below. Whilst I have come this far, a lot of it has been intuitive so I now have plenty of questions. Firstly I would like some help and clarification with regard to ebtables and especially how it works in a Virtualized environment on Novell SUSE 10 SP1 (1) ebtables Installation ebtables was not

Hello folks, I used to work with bridging for my xen networks, but my very last hosting provider doesn''t support multiple mac address on the switch port. So I''m trying to configure some virtual servers on xen 3.2.1 using the network-route and vif-route method instead of bridge. Everything works well, on the virtual server except the network. In the VM definition file, I have :

Hi, I have taken the long and winding road and indeed it lead me to your door. I need your help, please. My Xen includes 2 guests. Xen itself (10.2.0.52) gets free access to the outside world and to its guests. Both guests however (10.2.0.54/10.2.0.55) see each other but stay under house arrest! Not a single ping manages to go past the bridge (xenbr0) and get an answer from the default gateway
