similar to: network-bridge breaks networking when eth0:1 is added

I want to add the following route command route add -net 192.168.2.0/27 gw 192.168.2.3 via the normal network setup. The result should be the following routing table (the first line): 192.168.2.0/27 via 192.168.2.3 dev xenbr1 scope link 192.168.2.0/27 dev eth2 proto kernel scope link src 192.168.2.4 192.168.2.0/27 dev xenbr1 proto kernel scope link src 192.168.2.3 192.168.1.0/24 dev xenbr0

Hi, I've been using CentOS & Xen on a server that has 2 VM's configured. The default configuration includes one physical iface that is propagated (by a default bridge) to the VM's. Since I wanted to configure additional physical iface, define a new bridge and propagate it to the viface-s of the VM's, i configured the bridge/phys. iface and brought it up (here are

I am fairly new to xen and am trying to build a new guest using virt-manager. When I get to the screen where you can choose virtual or shared physical device there are no physical devices to choose from. Is there some step that I have missed while setting up my Dom0? -Joel Coopersmith Sr. Systems and Networking Analyst joel.coopersmith@accenture.com

Hi, until now, i have been using Xen 3.0.2. Now i upgraded to Xen 3.0.4. Can anybody confirm, that the ordner in the config files for the network interfaces has not changed? My config file used to read: vif = [ ''bridge=xenbr0'', ''bridge=xenbr1'' ] So inside the DomU, eth0 was attached to xenbr0 on the host and eth1 was attached to xenbr1. Now i upgraded to

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

As I received no response on the general CentOS list, I'll repost it here as the question is about Xen virtual machine routing. This is my network setup: http://pastebin.com/kyWpTQYU Lets assume my dom0's eth2 public ip is 1.2.3.33 and my dmz network 11.22.33.96/255.255.255.224 . I have created NAT from my LAN with iptables. You can see my /etc/sysconfig/iptables here:

I''m trying to get DHCP working with DomU clients. I don''t want to use libvirtd. There''s a dhcpd on the machine and it works fine for all clients in the network, but not for DomUs. If I set a static IP on the DomU all networking for them is fine, so there''s no general networking problem. I use the xen 3.2 packages for CentOS on CentOS 5.1. There was a public

Hi, I'm wondering about the impact of using both dom0 and domU's on a server at the same time. I'm worried about the performance impact of running a Mysql server in a domU and now I'm thinking about moving the Mysql part of a LAMP setup into dom0 and running a few Apache guests as domUs. Since the Apaches will serve mostly from an NFS share they won't have much impact on

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''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

I installed 64-bit xen 3.1.0 (from xensource.com tarballs) on three new machines today, using a configuration setup that I''ve used successfully many times before. However, I encountered a new problem. These are Dell Poweredge 1950 servers, by the way. >From lspci 04:00.0 Ethernet controller: Broadcom Corporation NetXtreme II BCM5708 Gigabit Ethernet (rev 12) 08:00.0 Ethernet

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, I''ve set up identical (what I think) machines using SLES 10 x86_64, but a new one of those is saying frequently in /var/log/messages: kernel: bond0: received packet with own address as source address A short summary of ifconfig looks like this: bond0 Link encap:Ethernet HWaddr 00:14:4F:2A:12:9C inet addr:132.199.176.78 Bcast:132.199.255.255 Mask:255.255.0.0 eth0

Hello, I have been playing with the XCP for a while now, and must say I''m very exited about the technology. I had no prior experience with Xen so it has taken me a while to understand the concepts, but now I feel most important issues are solved and I''ve purchased some hardware to build my (tiny) cloud on. The box is a Supermicro 1026TT-IBXF, so I have 2 x Ethernet and 1 x

I have a Xen DomU configuration that was made in the days before libvirt and virt-install. In this configuration I have: vif = [ ''mac=00:16:3e:05:06:01, bridge=xenbr0'', ''mac=00:16:3e:05:06:0a, bridge=xenbr1'' ] and then in xend-config.sxp I define (network-script my-network-bridge) where my-network-bridge is in the scripts directory and looks like this:

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.

My test box has an AMD dual core processor in it, giving me 2 physical cpu''s. If I overcommit the vcpu''s (eg vcpus=4) to simulate a 4 cpu machine, how accurate a simulation should it be (apart from performance sucking badly)?

I''ve attached a python script that collects stats from DomUs (HVM and PVM). I hope this would be useful for somebody else.

Hello, i am creating my XEN VM with virt-install (see below). When I create new images i do first an "df -h" to see if there is still enough space left on the drive. Are the XEN images pre allocated or does XEN only use that space that really is used by the VM inside the image? I know have the Problem that an "du -h" inside my /VM folder gives me nearly a higher number that

I realize this might be one of those religious topics, but is there any good rule of thumb as to how to setup storage for a Xen domU? Without really knowing any better, I''m basically going to make a disk image of the OS and the create a ''data'' partition on my raid 5 volume for each virtual machine. This is for use at home, so in reality it probably doesn''t
