Hello, I''m new to Xen (and this mailing-list) and facing some problems with the network. I''m stuck and don''t know how to continue. And Google isn''t very helpful either... My setup: - Ubuntu 7.10 for dom0 and Debian 4.0 for all domU - 4 physical NIC (DHCP from my ISP, internal LAN, DMZ & WLAN) - 1 Dom as firewall/router - 1 domU with internal services

Hi, I''m using Xen 3.0.3 on two servers with Debian Etch (amd64). These servers have 10 nics (2 onboard and 8 in two 4-port cards) so that every vm can have its own interface. This worked so far with the Xen Version from Etch with a wrapper script wich started 10 bridges at boot time. But now I''ve updated Xen on one of these server to Xen 3.2.0 from backports.org and now the

Hi! I have a problem with my new Xen setup. I have installed Debian etch with netinstall and I''m using 2.6.18-6-xen-amd64 kernel in my dom0 and 3.0.3-0-4 version xen hypervisor. I''m using four network cards on my system and using three of them as xen bridges and dom0 is using the fourth one only for it''s own. So basicly both of my virtual servers use a network card

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 all, I''m searching for a tutorial how to setup multiple network cards with xen network bridge setup in debian lenny. My problem is, bridges seams only to work if i put an ip adress in dom0 to them.

Hi There, I have a bit of an odd issue. I am testing Xen 3.0.2 on a machine before fully migrating to it from 2.0.7. The host OS is Ubuntu 6.06, and I am running the pre-compiled Xen code (kernel, tools) from the Xen site. I have two NICs, both if which I amhidung from Dom0 via the ''pciback.hide'' grub entry. I am have the bridges setup in the

Hi, I have a linux router with 4 ethernet cards; eth0 through eth3. Basically, all I want to do is route all traffic from eth2 to eth0, and all traffic from eth1 to eth3. I''ve looked through the LARTC how-to, specifically at chapter 4, about multiple providers. However, I am still a bit confused, and not sure how to set up my routing tables, as my scenario differs from the one in the

hi, after rebooting my host, i can''t have anymore the networking: here''s my output of /etc/init.d/networking restart Reconfiguring network interfaces...SIOCSIFADDR: No such device eth0: ERROR while getting interface flags: No such device SIOCSIFNETMASK: No such device eth0: ERROR while getting interface flags: No such device Failed to bring up eth0. done. cat

I have a setup with two Internet providers. One circuit (net0 == eth1) is used primarily for employees and tunnels to other sites. The other (net1 == eth2) is for the production machines that customers access. Everythung works in teh sense that packets get to where they are sent (mostly) but I recently I had a sniffer on the system and noticed a problem I cannot solve. traffic coming in

Package: xen-utils-4.17 Version: 4.17.1+2-gb773c48e36-1 Severity: important Dear Maintainers, On one of our domUs we discovered that the network interface names were wrongly assigned since recreating the domU after an upgrade to bookworm. If over 10 network interfaces are configured the mapping (dom0) vifX.10 <-> eth10 (domU) does not apply anymore. Instead the interfaces on dom0 are

Hi, I have been a shorewall user for a long time now, and it has been working flawlessly. I have now changed ISP and my new DSL connection is PPPoE. My setup is as follows: internet <--------> 3com812 Officeconnect (bridge mode) <----> eth0 <-------> linux box <----> eth1, eth2, eth3, eth4 <---> other internal networks Things are working fine, but the link is

I''m attempting to migrate from vmware to xen, however I need to be able to run more than one bridge. Think of it this way: xen0 xenU-1 xenU-2 xenU-3 ------------------------------------------------------------------------ Inside_bridge_1: eth0 vm1_eth0 vm2_eth0 virtual_switch_2: vm1_eth1 vm2_eth1 vm3_eth1 Outside_bridge_3: eth1 vm2_eth2 vm3_eth0 Now, I can modify the existing

Hi all, i have a xen 4.3 installation and would like to have a bridge bond szenario: *** eth0 eth1 | | bond0 | br0 | vif = [ ''bridge=br0,mac=xx:xx:xx:xx:xx:xx'' ] *** With the network script in debian wheezy *** /etc/network/interfaces auto bond0 iface bond0 inet manual slaves eth0 eth1

Hi All, I''m using xen 3.0 on CentOS 5 with VLAN. #vconfig add eth0 100 #/etc/xen/script/network- bridge start vifnum=1 netdev=eth0 bridge=xenbr0.100 I know that after xen 3.2 the procedure of bridge configuration is changed. What is the correct command to set bridge interface to vlan? Yukio

I''m running a ubuntu 9.04 64 bit dom0 with kernel 2.6.29.6 and xen 3.4.0. My eth0 is bridged to br0 and to my guest VMs. The dom0 is running a dhcp server on br0 which is able to provide leases to physical machines on eth0, and also to a windows xp domU which is bridged to br0. However my open solaris 2009.6 domU is unable to obtain a dhcp lease. On the opensolaris side I can see this:

(If this is a double post, I apologize, my email client crashed when I first sent it) I need some help to configure a secure network on my Xen server. I have been looking online and it seems a I need a routed network. But I am having a terrible time implementing it. My setup: Xen 3.4.2 CentOS 5.5 Dom0 1 NIC (eth0) All guests will be HVM What I want to do is something similar to a firewall

Hi, We would like to use VLAN tagged packets to be sent/received by the guest VMs running on xen hypervisor. Does xen bridging support vlan tagged packets arriving on the physical nic from outside of the xen host to be passed through with the vlan tag to the vif of the guest with the guest VM receiving the tagged packet ? We have a xenbr configured with two interfaces - eth3 (physical

Hello everyone, I have been able to get windows xp to run under a virtual machine, but i cannot get any network access. My desktop is connected to a university network, and we are only given 1 ip address. so i understand i have to use routing instead of bridging, right? i have commented the two lines for bridge and enabled routing in /etc/xen/xend-config.sxp next i inserted a line: vif

I have a OpenSuse 10.3 with xen 3.1.0 running and it''s been running fine for a few months. This past weekend it suddenly started to act up and after some troubleshooting I can now say that it seems like the guests(domU) loose the outgoing network pipe, from the console I can see that the TX counter is stuck at the same value but it''s no errors. It behaves as if whatever I try to
