I just tried to setup another domain on a server running 1 domain. When i try to start the domain it gives me an error Error: Device 0 (vif) could not be connected. Backend device not found. The entry in my xen config file for the disks is disk = [''phy:/dev/xen001/xen2-fun,sda1,w'',''phy:/dev/xen001/xen2-fun-swap,sda2,w''] Looking at /var/log/xend.log, i found

Hi, so here is finally my upgrade report for my testsystem.

I have built a dom 0 using a Gentoo Linux kernel. All is up and running with no errors. I downloaded a Centos 4.4 image from the web and when I rum xm I get an error 22. Does anyone know what I am doing wrong and/or where I can find more documentation on running unmodified VMX guest domains. The Xen 3.0 Users Manual is out of date. Here is the control file: sun temp # cat

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi together, last week I played around with XEN 2.0.5 and a Spirent performance test system.

Hello, I''m trying to deploy Xen in a Gentoo machine (Macbook Core 2 Duo), but I''m having a lot of questions and issues about installation and operation of Xen, mainly with backend drivers. The info is: - Machine: Macbook Core 2 Duo, it''s hardware is well known, but if needed I''ll post later my lspci. It has T7200 Core 2 Duo with Intel VT,

Thanks for your answers... But IMHO it''s hacky and error-prone to rely on the name of the host to determine if it''s a domU or a dom0 (or an unmodified kernel) :( I don''t like that much neither changing the name of the kernel :-/ I need to be able to determine, as a normal user (that is: non-root), if I''m running in a domU or not (I can already tell if

I''m running Xen 3.0.2 on a system that''s based on Slackware 10.2 as Dom0. DomU is also slackware 10.2. Am using the kernel that came with 3.0.2 - no custom config, just a "make world", etc.. Did have to add grub of course. When I start up xend, I get the following on /var/adm/messages: Apr 23 21:04:11 rc25 kernel: Bridge firewalling registered Apr 23 21:04:11 rc25

Hello all, I post again a question I asked few weeks ago : when you change the /boot/grub/grub.conf of a domU, the modification is not taken into account by pygrub, until you reboot the dom0. Restarting xend has no effect, nor deleting the temporary kernel and ramdisk located in /var/lib/xen. This morning I had to reinstall one of my old domUs, the grub.conf changed and the domU did not

I have a server with dual etherports, eth0 and eth1. Before starting xend, I can connect to the server (dom0) on both IP''s. I have Xen configured so that it sets up the network-bridge on eth1; ie, in /etc/xen/xend-config.sxp: (network-script ''network-bridge netdev=eth1'') When I start xend, the bridge starts up on eth1, and then I can''t connect to that

Hello, Where can I find a link (or docs) to *working* network config for xen 4.1.2? My tests (s. below) were not successful. Thank you in advance for any hints.

Hi all, I am running Xen 3.0.2-2 (taken from XenSource) with Linux kernel 2.6.16 (taken from Debian Sid), I compiled Xen and 2 kernels (dom0 and domU).

Hi, I''ve been having troubles with bridge networking in Xen3. RHEL4 is running in dom0 and Debian sarge in domU. Both domains get their IPs from an external DHCP server. dom0 starts up OK and gets its IP from the server. (all networking services work fine; in and out) domU starts up OK and sometimes gets its IP while sometimes fails to get the IP. In any case, after logging into domU

Greetings! Trying to to run a xen3 domU on a xen4 dem0 I run into problems. The xen server ''XEN1''(dom0) is openSUSE-11.3 (kernel 2.6.34) and xen-4.0.1. With qemu I created an image ''M08.raw'' from the SUSE-9.3 (kernel 2.6.11) and XEN-3.0 installation CD''s. The XEN modules were included in the installation. In M08.raw/boot I configured grub/menu.lst:

Hi folks, I am trying to get antispoofing running on xen3 (based on Debian Sarge). This is what I have done to enable it: 1. I have compiled a dom0 kernel with CONFIG_NETFILTER_XT_MATCH_PHYSDEV=m 2. I made sure this module is loaded: lsmod gives xt_physdev (among others). 3a. I have changed the line "(network-script network-bridge)" to "(network-script network-bridge

Hi all, This is a dom0 NAT question. /etc/xen/xend-config.sxp (network-script my-network-bridge) (vif-script vif-bridge) there are two physical network cards on the box and my-network-bridge creates two bridges. domU''s use these bridges. I have some windows pc''s connected to one of the nics and I would like to use dom0 route their traffic and do SNAT. (firewall/router setup)
