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 all, I have a very strange situation, which I can''t explain. On a Core 2Quad server with 8GB RAM, we have 10 xen domU''s, as follows: vps.animalsaregreat.info login: root@zaxen01:[~]$ xm list Name ID Mem(MiB) VCPUs State Time(s) Domain-0 0 512 4 r----- 232.2 actionco.vm

Well where do I start...I have a domU (ubuntu) booting and appears well but I don''t have an eth0 listed at all, dom) looks good.

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

I''ve looked everywhere for the error message I''ve posted in the title, doesn''t seem like anyone else has it (lots of missing hotplugs scripts). We''re using network-nat. ifconfig -a outputs this: eth0 Link encap:Ethernet HWaddr 00:19:99:a8:f4:5c inet addr:X.X.X.X Bcast:X.X.X.X Mask:255.255.255.255 inet6 addr: X::X:X:X:X/64 Scope:Link

Hello. I need your help, DomU xen network diconnects randomly, how do you monitoring this?

Hi, I tried this post on the Xen list first with no answer. I have 4 machines and 3 of which (all different) have no network access when booted into Xen. I tried using Fedora Core 8 and it produced the same results. Is it normal for the virbr0 interface to take an arbitrary IP? How does it decide what to use? An ifconfig when booted into Xen shows the following: eth0 Link encap:Ethernet

Hello. I''ve just started with Xen and configuring Dom0. My hardware is Core2Duo based Xeon server and I installed Debian etch for amd64 architecture.

I'm recording TCP network throughput performance between Dom0 IP stack and all my guest domains (currently 6 running simultaneously). All guests are running simultaneously, but I only ever transmit between Dom0 and one of the DomUs while the other five are idle.

Hi, I have 3 xen box with 2-3 VM on each. Each server has 2 nic (1 for external and 1 for internal network). All VMs are webserver and they mount a nfs filesystem.

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'']

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 folks, I''ve been trying to work out this situation for a few days now without much success and dug all over the archives for similar issues, none of which seem to relate exactly. I installed Debian Etch and the Xen (3.03) kernels / binaries on a Dell server. It works fantastic with all the default configurations with one strange flaw - as soon as the /etc/xen/scripts/network-bridge
