Hi, This is my setting: I have a Logical Volume /dev/VG/suse with Suse installed. I have added it to the grub and I can boot it and works perfectly fine. Now I am running /dev/VG/root which is running Xen0. I have created a Xen config file to boot a VM with disk: /dev/VG/suse. In other words I want to boot /dev/VG/suse as a virtual machine. Below is what I am getting at boot time :

Hi, I have a strange problem with my networking setup. I read all forums around the world where people had similar problems, but couldn''t find a solution. I have an Attansic L1 gigeth chip on my mainboard. This chip works OK in stock Ubuntu Gutsy (development) 2.6.22-9-generic kernel. When I boot into Xen, and after the bridge is created, the network stops working. Some info: - If I

Hi, I am using Xen 4.1.1 with Linux 3.0.1 kernel. Previously (Xen 3.4.4 and linux kernel 2.6.18) Xen by default created veth0 <--> vif0.0 pair in dom0. With Xen 4.1.1 these pairs are missing in dom0. Using command ''ip link add type veth'' I can create veth0 and veth1 but vif0.0 is still missing in dom0. (When new domU created I can see vif1.x created) Could you please help

Hello you all out there Does anybody know the definite guide to create a dummy ethernet device? So, what I want to have is an ethernet device, without a physical link, or so called a dummy device. My goal is to have apache with mod_proxy and balancer running on peth0 in dom0. Apache is spreading my connection to the backend domU''s, where the webservices are running. The connection

Hello, Despite of reading a lot of descriptions I don''t understand the network configuration. I simply have too little experience. I work remote with the machine via ssh. My dom0 is running. I copied an existing installation into a LV and created the following file: # cat /etc/xen/domu-sarge # -*- mode: python; -*- kernel = "/boot/vmlinuz-2.6.18-4-xen-686" #kernel =

Hello All, I'm trying to figure out why xen-utils-common 3.2 doesn't suport bridging on multiple interfaces. I've been digging around /etc/xen/scripts/network-bridges. And modified it so that during boot, when executed the script writes into /tmp/netbr file, but I commented out code that actually creates bridges. I discovered that this script is called three times during boot, I

I have a new x3655 IBM and whenever the /etc/xen/scripts/network-bridge script starts, the ethernet would no longer work. This post isn''t about the cause, but the fix. I did a lot of tcpdumps and Googling, but I''ll spare you that. All they do is prove that yes, there is an issue. :) I tried Debian 4.0 i386/amd64 and Ubuntu 7.04 Server i386/amd64 and they all exhibit the

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
