I have the following networking setup: - eth0 and eth1 corresponding to the physical ports on the host NIC - bond0 which enslaves eth0 + eth1 - br0 which attaches bond0 - xenbr0 - xenbr5 all of which are internal only networks (10.0.0.0; 10.1.1.0; etc) Br0 is used both for the host to access the outside world as well as DomUs acting as gateway machines for each xenbr network. For example the DomU named Gateway0 will have eth0 attached to br0 giving it connectivity to th...

Hi, does somebody know, if there is any documentation available on how to set mac addresses on virtual bridges / virtual interfaces? Keeping track of every mac in the particular segments is really impractical.

Hi I''m testing around with xen 3.0 snapshot from last week. And i''m now having a problem with a xenbr which is based on a vlan if (dot1q). this is all in dom0 os: debian testing network: tg3 I can start the bridge based on my normal physical eth0 which is working without any problems. My clan without bridge is also working. I can start the bridge based on a vlan if with help of the following com...

...ever I could "google" on this topic, I didn`t find any solution: openSuSE 10.2 (out of the box), xenkernel, running on HP Proliant DL360G5 (dual internal networking, plus additional 4-port adapter) gives me eth0 - eth5, but only peth0 - peth3 (as well as vif0 - vif3 and consequentely xenbr0 - xenbr3). I increased the number of loopback-devices to 64 ... no result Whenever I try to "/etc/xen/scripts/network-bridge start vifnum=4" I get a message regarding to a "nonexisting veth4" ... What am I missing Thanks for your time Joe _______________________________...

Hello everybody, Here again with a Xenbr0 bridge problem I''m a Gentoo user, xen-sources-2.6.34 and I always used the bridge from eth0 to xenbr0. Here''s what I get at boot time: * Bringing up interface eth0 * null [...] * Starting Xen control daemon ... And the bridge doesn''t come up. The normal behaviour s...

The network-bridge script is fragile because of how grep is used. As one example, if I already have "xenbridge", I can''t create "xenbr". (It''s actually worse than that, because it''s even grepping the header output by brctl show.) Assuming dom0 is on Linux with /sys mounted (is that a safe assumption?) we can check for the existence of a bridge, and check if a...

...nnect, and public IPs as follows; eth0 - public (routable and registered in DNS) eth1 - private (not routable, uses a seperate network subnet for 10.10.0.XXX) eth2 - RAC (routable and registered in DNS) Right now, all of the guest OS nics are being connected to eth0 of the physical host, using xenbr0. I know that an entry needs to be made in /etc/xen/vm/xen-host-name config file that looks like; vif = [ ''mac=00:16:3e:66:99:23, bridge=xenbr0'', ''mac=00:16:3f:66:93:3d, bridge=xenbr1'' ] But I am unfamiliar with how to initially setup and configure additiona...

Hi Everyone, In my HVM guest''s config file, I have given my guest 3 interface. I have called them fw1, fw2 and fw3. I have joined each interface to a bridge on the Dom0. This does appear when I do a "brctl show". However, there are 3 other interfaces also added called tapx.0,tapx.1 and tapx.2 (Where x is the domain ID for the guest). Furthermore, I am only able to run

...ets 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 nic of the host), vif23.2 (vif of guest VM running in domain 23). Sniffing the packet just outside the physical NIC does show that it has the vlan tag, but tcpdump on eth3 shows that the vlan tag has been stripped. Any ideas pls ? Looks lik...

I created my first Xen VM that didn't use a static IP address. It grabs an IP from the 198.168.122.0 subnet (from I don't know where). I would rather want it to use my DHCP server. How can I achieve this? Kai -- Kai Sch?tzl, Berlin, Germany Get your web at Conactive Internet Services: http://www.conactive.com

...I see links here: http://packages.qa.debian.org/l/linux-2.6.html But they don't work, e.g: http://packages.debian.org/search?keywords=linux-modules-2.6.26-1-xen-amd64 I uploaded the amd64-packages to my site: http://www.vandervlis.nl/xen/ They are working for me (I have only problems with the xenbr devices). I don't know it's possible to get them in Etch. But for that case we need to test them, I think. With regards, Paul van der Vlis. -- http://www.vandervlis.nl/
